Abstract:

The melting of scrap and hot briquetted iron (HBI) in an AC electric arc furnace (EAF) is simulated by an advanced 3D computational fluid dynamics (CFD) model that captures the arc heating, the scrap/HBI melting process, and the solid collapse mechanisms. The CFD model is used to simulate a scenario where charge layering and EAF power profiles are provided by a real EAF operation. CFD simulation of the EAF operation shows proper prediction of the charge melting when compared with standard industry practice. Namely, the CFD model predicts a 32.5%/67.5% ratio of solid/liquid steel at the beginni

The measurements of injected charge mobility in solid parahydrogen reveal that the mobility of negative charges along the solid-liquid interface decreases with increasing temperature, while the mobility of positive charges increases. This points towards a considerable difference in the structure of charges of opposite polarities in para-H2 hcp crystals.

The melting of large-diameter crystals using an orbital solar concentrator is studied numerically. In the proposed configuration, a parabolic dish imaging concentrator is used to focus the sun’s radiation onto an ampoule which holds the solid charge material to be processed. The charge will start melting in the vicinity of the focal height, after which it is translated in order for the melt to resolidify as a single crystal. A ray-trace method has been developed to determine the incident concentrated solar heat flux on the ampoule’s surface for both perfectly aligned and misaligned configurati

The article presents the results stemming from the calculation of the arc efficiency of arc steel melting furnaces during melting of scrap and metallized pellets. Furnaces that use metallized pellets are characterized by less arc efficiency and a higher electric energy consumption than similar pellet furnaces.

The results show that a positive linear relationship exists between the slag melting behavior and the melting–dropping property of the corresponding charge.

Abstract Charge ordering is one of the interesting phenomena exhibited by doped rare earth manganites. Along with the application of a high magnetic field and variation of composition and temperature, the intrinsic method of size reduction to nanoscale is a much investigated method of ‘melting’ the charge order. However, the question of complete melting of charge order versus the melting of only the long range charge order is not yet fully settled. Investigating small enough and monodisperse nanoparticles should help clarify the point. We have prepared nanoparticles of La0.375Ca0,625MnO3, Nd0.

These problems could be related to the snow melting that was going on.

Abstract:

In this study, the melting of different types of phase change materials in a heat exchanger, the effect of porosity, triangular fins, and the addition of aluminum oxide, titanium oxide, and copper oxide, nanoparticles on the thermal behavior of four types of materials are studied numerically. The enthalpy porosity method is used during the melting process. The main heat transfer fluid is non-Newtonian and the tube is filled with a porous medium. The nanoparticle volume fraction is varied from 0 to 10%, the fin height is considered from 0 to 6 mm, and the porosity is considered equal to 0.8991,

Abstract:

A model for calculating phase equilibria between a liquid and a crystal is proposed, which makes it possible to evaluate the melting points of ionic compounds. The dependence of the melting temperatures of alkali halides on the cation-anion composition can be described in terms of ionic radii and polarizabilities using thermodynamic perturbation theory for the molten phase. The chemical potential of the crystal phase contains the Born-Mayer formula for the electrostatic part of the energy and the Debye formula for the vibration contribution. The full system of equations describing the equilibr

<strong>ABSTRACT </strong> The cupola is a refractory lined shaft furnace and the basic fuel is coke. The main objective of the present work is the utilization of waste material (Rice husk briquette) of low C.V. to 50% eq. of split coke charge. Bed coke remains unaltered due to breakdown of rice husk briquette on heating in a cupola. The experiment was carried out in a single blast cupola 23-inch internal diameter (ID). Four charges were tested out of eight charges. There was no change in composition, melting rate, spout temperature, and slag chemistry, but SO<sub>2 </sub>emission was reduced

Abstract:

Stainless steel is mostly manufactured by Electric Arc Furnace Argon Oxygen Decarburization route utilising 100% solid charge of steel scrap/DRI/stainless steel scrap and ferroalloys.The process consumes around 415/450 KWH of power per ton of stainless steel.In the state of Odisha, we are endowed with both iron and chromite ores,which offer opportunity for use of molten pig iron and liquid ferrochrome for energy efficient stainless steel making for a plant located there. This paper analyses potential for energy conservation in EAF for three different grades of stainless steel belonging to AISI

Abstract:

In the present study, the performance of a heat storage unit consisting of number of vertical cylindrical capsules filled with phase change materials, with air flowing across them for heat exchange has been analyzed. Earlier theoretical models did not consider temperature distribution in the radial direction within the capsules, an assumption that limits their applications for small diameter capsules. The mathematical model developed in this work is based on solving the heat conduction equation in both melt and solid phases in cylindrical coordinates, taking into account the radial temperature

For the smelting ferrotungsten of raw materials (mineral) took us to calculate the charge for each experiment. To optimize the process of obtaining ferrotungsten of wolframite carried out the following activities: to reduce speed and combustion temperature. A change batch positive impact on the development of the combustion process. Experimental results have shown the effectiveness of the introduction of aluminium additives in excess of stoichiometry because the explosive burning regime turned into stationary. In this work the charge calculated on 300 g volframite concentrate so that as a resu
