Abstract:

This paper studies the process adaptability of reclaimed clay sand with core sand, and discovers that the reclaimed clay sand with furan resin self-setting sand can be used to mix the water-glass sand and hot core box sand; but it can not be used to mix the cold core box sand and coated sand. The reclaimed clay sand with water-glass sand can not be used to mix the hot core box sand, cold core box sand and coated sand; the reclaimed clay sand with hot core box sand can be used to mix the water-glass sand, cold core box sand and coated sand; the reclaimed clay sand with cold core box sand can be used to mix the water-glass sand, coated sand and hot core box sand. The reclaimed clay sand with coated sand can be used to mix the water-glass sand, but when it is used to mix the hot core box sand and cold core box sand, it can meet general requirements of the casting production; the completely reclaimed clay sand can not be used to mix the resin self-setting sand.

Abstract:

The technological adaptability of the reclaimed sand applied in the chemical bonded sand was studied in this paper. The reclaimed sand can be obtained by the process of high-temperature baking followed by mechanical reclamation and separation of micro-powder. The reclaimed green sand which containing different types of chemical bonded core sand were applied in corresponding system of chemical bonded sand process, such as the process of cold-box sand, hot-box sand, precoated sand, sodium silicate sand and self-hardening sand. Through technological experiments, it can be found that the tensile strength value of the precoated sand and sodium silicate sand which were prepared using reclaimed sand can be equal or slightly higher than that of prepared using the base sand, the tensile strength value of the cold-box sand, the hot-box sand and the self-hardening sand which was prepared using the reclaimed sand are lower than that of prepared using the base sand. Compared with the chemical bonded sand requirements in the foundry practice, the cold-box sand, the hot-box sand, the precoated sand which was prepared using the reclaimed sand can still meet the casting process needs, but the self-hardening sand which was prepared using the reclaimed sand cannot meet the casting process needs.

Abstract:

Highlights The drying effect in the drying layer is affected by the status of the flow field. The angular box of the drying oven is optimized to improve the drying effect. The structure of the variable-section angular box significantly reduced unevenness and improved the drying effect. Abstract . Dryers are subject to problems as they are unable to fully and uniformly dry grain. Considering the mixed-flow drying process and improving the drying uniformity, this study conducted a numerical simulation of the hot air temperature field, velocity field, and pressure field with ordinary equal cross-section. The dryer was optimized by a variable-section angular box structure for simulation analysis and experimental verification. The results demonstrated the following: the optimized variable cross-section angular box can improve the uniformity of the overall flow of hot air in the drying box; that is, it diffuses uniformly in the temperature, speed, and pressure field of hot air. A comparative analysis of equal cross-section and variable cross-section angled tubes indicated that the unevenness coefficient of the tubes’ wind field of the same section was reduced from 81.31% to 66.8%, 51.19% to 32.78%, and 56.98% to 42.57%, which significantly reduced unevenness and improved the drying effect. Keywords: Angular box, Flow field distribution uniformity, Grain drying, Numerical simulation.

Abstract:

The determination of the thermal performance of hybrid insulation assemblies that include an enclosed reflective airspace and a separate layer of insulation is being done using a hot-box test facility operated in accordance with ASTM C1224, the Standard Specification for Reflective Insulation. The thermal resistance determination of the insulated region requires a hot-box test with known thermal insulation to determine heat flow through the framing. Factors that affect the result for the hybrid insulation assembly will be discussed along with results obtained using the ASTM C1224 protocol. The thermal resistance obtained using the hot-box apparatus will be compared with calculated values obtained from published correlations. The uncertainty in the hybrid insulation assembly and the enclosed reflective airspace due to uncertainty in the thermal resistance of the calibration material are of particular interest.

Abstract:

The green sand containing hot-box resin sand was reclaimed by the process of calcination followed by mechanical reclamation. The reclaimed sands were reused in the hot-box process. The grain size distribution, the shape factor, the clay content and the acid demand value were determined. The results show that the acid demand value of the reclaimed sand is higher than that of the base sand. Compared with the base sand, the grain size of the reclaimed sand is almost no difference. It can also be observed that the tensile strength of the molding sand is influenced by the acid demand value and clay content, but the reclaimed sand can still meet the casting process needs. In addition, the reclaimed green sand is satisfactory for hot-box process.

Abstract:

In this paper, a novel integrated measuring and control system for hot box experiments is presented. The system, based on a general-purpose microcontroller and on a wireless sensors network, is able to fully control the thermal phenomena inside the chambers, as well as the heat flux that involves the specimen wall. Thanks to the continuous measurements of air and surfaces temperatures and energy input into the hot chamber, the thermal behavior of each hot box component is analyzed. A specific algorithm allows the post-process of the measured data for evaluating the specimen wall thermal quantities and for creating 2D and 3D thermal models of each component. The system reliability is tested on a real case represented by a double insulating X-lam wall. The results of the 72 h experiment show the system’s capability to maintain stable temperature set points inside the chambers and to log the temperatures measured by the 135 probes, allowing to know both the U-value of the sample (equal to 0.216 ± 0.01 W/m2K) and the thermal models of all the hot box components. The U-value obtained via hot box method has been compared with the values gathered through theoretical calculation and heat flow meter measurements, showing differences of less than 20%. Finally, thanks to the data postprocessing, the 2D and 3D thermal models of the specimen wall and of the chambers have been recreated.

Abstract:

One of the methods used for determining of the thermal conductivity coefficient value of building materials is the Calibrated and Guarded Hot Box method. This method is based on the principle of measuring the heat flux density that passes through the test specimen at a temperature difference between warm and cool parts of the measuring box. For measuring of thermal conductivity coefficient is at the Faculty of Civil Engineering of VŠB-TUO used the Cool Box. Measuring in Cool Box uses the same principle of measuring as Calibrated and Guarded Hot Box. For creating temperature difference during the measurements at the Cool Box is not used heat, but cold. Measurement of the thermal conductivity coefficient by a Cool Box is very complex in terms of measurement accuracy. That the resulting values as accurate as possible, it is necessary to calibrate itself refrigerated cabinets and all sensors that are used for measurements. This paper describes the principles of calibration of Cool Box and other components, which are used for measuring the thermal conductivity coefficient of selected natural building materials. Determination of the thermal insulation properties of selected materials is part of a long-term research focused on conventional and unconventional natural building materials.

Abstract:

This paper presents the results of experimental and numerical studies of the hot distortion phenomenon in the phenolic urethane cold box systems used in metal casting. Dual Pushrod Dilatometry has been used to measure a thermal expansion/contraction of phenolic urethane cold box sand core specimens at temperatures ranging from 20°C to 600°C. High temperature tensile tests showed that the tensile strength of the phenolic urethane cold box sand cores is significantly affected by the bench life, temperature and binders level. High temperature hot distortion furnace tests on cylindrical cores showed that some coatings increase the temperature limit when distortion starts, but application of coating cannot prevent distortion. The hot distortion test during metal casting showed that regardless of the application of coating, the type of coating, and anti-veining additives, all cores with density greater than the density of the molten metal (magnesium alloy) were significantly distorted. Numerical simulations of the liquid metal flow around the cylindrical sand core and analysis of dynamic forces acting on the core during the fill process showed that a buoyancy force is the major contributor to the hot distortion. It is concluded that the one of the solutions in preventing the hot distortion of sand cores is optimizing their weight, which will balance the buoyancy force and will bring the resultant force to the minimum. The hot distortion test castings using optimized sand cores with density almost equal to the density of the molten magnesium proved our predictions, and hot distortion has been prevented.

Abstract:

In this paper, four typical building roof modules, i.e., sedum linear module, lightweight planting soil module, water-retaining board module and XPS module, were experimentally investigated by using the guarded hot box under real weather condition in Guangzhou, China. The testing results were compared and analyzed regarding to three main properties of the roof module, i.e., the top and bottom surface temperatures of the modules, air temperature inside the inner box of the guarded hot box and temperature attenuation characteristics for the thermal insulation of the modules. It was found that the sedum linear module performed well in the thermal insulation property under the typical summer weather condition. The analysis results could be used to assist in the application of the green roof module, and contribute to the energy conservation of the buildings.

Abstract:

For achieving the maximum energy efficiency of Building-integrated Photovoltaics (BIPV) buildings, the Solar Heat Gain (SHG) through the BIPV modules should be measured accurately. A solar calorimetry hot box was designed to test the SHG through the BIPV modules in this paper, which could measure the incoming solar and long-wave radiation various BIPV module configurations. Combined with the electric energy production, a new concept of ratio of solar heat gain to power energy generation efficiency was presented in this paper, which can be characterized as the design indicator of BIPV module’s energy efficiency level for BIPV buildings cooling in hot summer. The influence of indoor climate environment parameters on the electric energy output efficiencies of BIPV modules can be conducted by the solar calorimetry hot box.

Abstract:

The main purpose of the HeLLo project is to contribute to data available on the literature on the real hygrothermal behavior of historic walls and the suitability of insulation technologies. Furthermore, it also aims at minimizing the energy simulation errors at the design phase and at improving their conservation features. In this framework, one of the preliminary activities of the study is the creation of a real in situ hot box to measure and analyze different insulation technologies applied to a real historic wall, to quantify the hygrothermal performance of a masonry building. Inside this box, ‘traditional’ experiments can be carried out: recording heat flux, surface temperature, and air temperatures, as well as relative humidity values through the use of a new sensing system (composed of thermocouples and temperature/relative humidity combined sensors). Within this paper, the process of development, construction, and validation of this new metering box is exhibited. The new hot box, specifically studied for historic case studies, when compared to other boxes, presents other advantages compared to previous examples, widely exemplified.

Abstract:

This study used observations of crime strategy meetings and interviews with police commanders to “get inside the black box of hot spots policing.” The findings focus on what the studied police commanders believed they were doing and why they believed those tactics would be effective during hot spots policing implemented under non-experimental conditions. An example causal model for the effectiveness of hot spots policing that emerged from the data is presented. While the commanders’ views aligned with commonly used policing tactics and crime control theories, their underlying theoretical rationale is complex. The presented model provides one causal model that could be tested in future hot spots policing evaluations, and a discussion is presented of how the study’s methodology can be applied in other jurisdictions to define localized causal models and improve hot spot policing evaluations.

Abstract:

The negative effects of violent content in movies have recently been a hot topic among both researchers and the general public. Despite growing concern, violence in movies has persisted over time. Few studies have examined why this pattern continues. To fill this gap in the literature, we examine how Motion Picture Association of America (MPAA) movie rating descriptors predict ticket sales of 2,094 movies from 1992 to 2012. We test the validity of three theoretical models: (1) the reflective model, (2) the reactance model, and (3) the market model. We find that violent content is linked neither to violence in the broader U.S. culture (i.e., the reflective model) nor to a psychological reactance by adolescents (i.e., the reactance model). Rather, we find, especially among PG-13 (parents strongly cautioned) movies, that violent content leads to increased ticket sales, suggesting that market demand (i.e., audience preferences) is responsible for continued violent content. We discuss the implications of our findings.

Abstract:

The production technology for automotive foundry castings has developed significantly during the past decade. The production of cylinder hats with more and more complex designs could be rather challenging for core makers. Heating might cause the annealing of the core, thus, the buoyancy of the molten metal increases which might cause the movement of the core. The heat distortion of the cores was examined with a Hot Distortion Tester. A universal Instron 5982 device was used for bending, wedge penetration strength and cold and hot compression tests. The test bars were prepared with cold- and hot-box processes using DMPA (Dimethylpropyl-amine) under laboratory conditions. The tests showed that the decrease of the bending strength is proportional to the amount of additives. The compression test results showed that the test bars produced with cold-box compression have the lowest and the ones with furan resin mixtures have the highest compressive strength.

Abstract:

Abstract Mechanization of the process of core making with the use of inorganic and organic binders is based, almost solely, on core blowing machines. Presently the core blowing machines are equipped with tools and devices that allow for application of different technologies of core making. Cold-box, hot-box and warm-air technologies require that core blowing machines shall be additionally equipped with either core-box pre-heating system or gas purging and neutralization system, or hot air purging systems. Considering the possibility of using varied, the most advantageous technologies of core making, the production of universal core blowing machines equipped with replaceable devices has been undertaken in Poland. The universal core blowing systems allow for mechanization of core making process also with the use of sand, bonded by modern, eco-friendly binder systems. The paper presents selected results-based evaluation of core blowing process showing the scope of conducted design and implementation works.

Abstract:

This article considers the working practices of British cinema's only major female film producer during the early-to-mid post-Second World War era, Betty E. Box (1915–99). Via reference to her extensive archive at the British Film Institute and the films Campbell's Kingdom (1957), The Wind Cannot Read (1958) and Hot Enough for June (1964), the article charts how Box initially envisaged multi-generational casting for roles that were eventually taken by long-term collaborator Dirk Bogarde. It considers the manner in which she approached the diplomatic complexities of location shooting, with particular focus on Ralph Thomas's military romance The Wind Cannot Read, the first British film to be shot in India for twenty years at the time of its production. The reasoning for Box's ongoing absence, as a female creative figure, from scholarship addressing British cinema, and film production more generally, will also be addressed.

Abstract:

A versatile hot box-cold box test facility called HAMSTER enables to evaluate the energy and hygrothermal performance of up to 3m high, 3m wide and 3.6m deep building test elements including walls, flat or pitched roofs and floors. This equipment allows for the precise measurement of thermal performance according to standards. It also allows for the study of heat, air and moisture phenomena taking place in building elements under realistic climatic conditions including the effects of rain, sun or wind. Interior and exterior climates are simulated in, respectively, the hot and cold chambers by controlling the temperature, relative humidity, pressure difference between both chambers, infra-red or solar simulator heating and water spraying in the cold chamber. Critical issues that have been solved during the design and construction phases in order to reach both the required performances and the versatility of the test facility are discussed.

Abstract:

A prototype of photovoltaic semiconductor cooling box was designed based on the demand of energy saving and environmental protection. This paper presents the composition and working principle of the prototype. The data of the lowest internal temperature of the cooling box was gained by measuring the actual operational performance of the system at different ambient temperatures. And according to the experimental results, the coefficient of performance of the system was derived. The obtained results showed that the minimum air temperature inside the cooling box can be maintained within 6~10°Cand the coefficient of performance can reach up to 0. 28~0.32 in the hot summer days.

Abstract:

The production rate of scalar-particle pairs from finite temperature (T) plasma of massless-scalar particles confined in a cubic box of volume V is calculated. The Dirichlet boundary conditions are imposed on the wall of the box. The finite volume effect is found to be quite large at T=(2−3)×102 MeV and V=[(1−5)×10−13 cm ]3, the numerical values which have been estimated for the quark-gluon plasma produced in heavy-ion collisions at CERN SPS and LHC energies.

Abstract:

A new model of the refrigerator with refrigeration and constant temperature and hot water has been trial-produced. The new refrigerator can not only keep refrigerated food quality, but also be used for heating or keeping food temperature constant, and supply hot water for us. The subsystems of condenser have been analyzed and designed including air-cooled method and water-cooled method. According to the theoretical calculation, the temperature in constant temperature box can keep about 50°C and 18.46 Kg hot water can be provided per hour.
