Abstract:

Recent research in the process of die casting production of aluminium alloys which are nowadays deeply implemented in the rapidly developing automobile, shipping and airline industry aims to increase the manufacture and quality properties of the casting in order to obtain its high mechanical properties at acceptable economic costs. In terms of ensuring the quality indicators in the production of aluminium castings it is necessary to pay close attention to internal structural quality of the castings characterized by type and extent of foundry defects (cavities, Al2O3 particles, internal cold la

With the help of innovations at an industrial enterprise, it is possible to increase labor efficiency and reduce the resource intensity of production. The relevance of the development of the technology of metal casting in sand molds, as the most common casting process, is justified by the fact that up to 80 % of the tonnage of castings is produced in such molds, including special types of casting in molds from sand materials. 60-70 % of the equipment capacities, areas, and personnel of foundry shops are attributed to molding processes, including mixing and rod production.

The article is devoted to the developing of a methodology for determining the duration of the technological cycle of cooling castings during the aerodynamic movement of dispersed refractory in containers of foundry rotary-conveyor lines. The use of rotary-conveyor lines is an effective solution for increasing the productivity of foundry technologies. To comply with the principles of construction of rotary-conveyor lines, the cooling time of castings in a mold, as one of the longest technological processes, must be minimized. This can be achieved by forced cooling of castings using the aerodyna

Foundry in developing nations endures from low quality and low output due to the incidence of defects that may occupy single or multiple causes. Hence casting is a process of uncertainty.

Abstract:

Each casting produced in a foundry is a research experiment, since no two castings have the exactly same values of their geometric, material and process parameters. By the time, castings are inspected the link to the originating (influencing) parameters is lost, since they are never systematically recorded and correlated with quality characteristics. Thus, a valuable opportunity to improve casting quality is lost. In this work, we present a systematic approach for classifying casting defects by correlating them with the originating parameters; the proposed classification approach is hierarchic

The traditional method has been used to the foundry technique for the cast-steel casting. And the commercial foundry simulation software was used to validate the rationality of the foundry technique. Four side risers and some cylindrical chills were used to decrease the shrinkages which would occur in casting. The results show that the risers could not feed the casting effectively because of the limited feeding distance. A top riser was introduced to eliminate the defects, the simulation results show that still some shrinkages occurred because the heat effect between risers. The side risers we

Abstract:

High-temperature heat shock is caused by pouring a liquid alloy (cast iron in this case) into cavity of a wet sand mould. In the mould material, thermal-chemical-physical phenomena of very high intensity occur. These phenomena are important in metal alloys casting only insofar as they influence quality of a casting (dynamics od solidification and casting’s structure, gas and shrinkage defects). This quality can be forecasted using simulation codes dedicated for the foundry branch. The most important phenomena are subject of hard and/or soft modeling.

The evaporative casting method is to use Styrofoam as a pattern dumped in the printed sand. This method will produce castings that match the pattern of Styrofoam made.

Abstract:

Foundry sand, an indispensable component of the metal casting process, is discarded after a number of metal casting operations. Virgin sand is then required for any new casting processes, and the spent foundry sand is treated as waste, resulting in huge amounts of discarded sand being either stockpiled or dumped into landfills. This results in a wide scale consumption of natural resources despite the fact that this “waste” can be recycled as a viable resource in various engineering processes. To this end, this study represents a detailed investigation into the possible uses for waste foundry s
