This paper describes an approach to furnace charge calculation for melting processes, achieve a specified target melt in crucible or induction furnaces with minimum material cost. There has been challenge the problem regarding loss, contaminations, and unwanted physiochemical reactions during process. Those put high degree of complexity, non-linearity, uncertainty on calculations. The current s...

The purpose of this paper is to show the results of some work at the IRC in Materials for High Performance Applications at the University of Birmingham into the effect of processing and process parameters on the microstructure, macrostructure and chemistry of 100 mm diameter single plasma-melted ingots of a gamma-based titanium aluminide (Ti-48at%Al-2at%Mn-2at%Nb). The microstructure of the aqm...

In this work, a numerical analysis was performed about the effect of flat-flame burner incidence degree on heat transfer an industrial scale frit melting furnace, which uses natural gas oxy-combustion burner. The thermal performance furnace evaluated by predicting temperature distributions, recirculation combustion gases, and flow to load, using three different geometrical configurations, diffe...

This paper describes Microwave Activated Combustion Synthesis (MACS) of intermetallics of technical importance in the Co-Si binary system. These materials have important electronic applications as thin films. Bulk CoSi2 is required for use as a target for the production of thin films in sputtering processes. Sputtering targets are generally processed either by a powder route, casting or mechani...

The paper presents the results of a comprehensive study thermophysical properties 21 samples skull and refractory lining collected after blowing out blast furnace No. 6 (EVRAZ NTMK). open porosity, apparent density, melting point, thermal coefficient linear expansion (TCLE), diffusivity, heat capacity are determined, their conductivity is calculated. coefficients standard approximation equation...

In order to reduce energy consumption in the blast furnace ironmaking process, it is important promote not only rapid reduction of ore but also carburization and melting metallic iron. this study, use carbon-iron composite which an agglomerate fine iron carbonaceous material was focused on, effects type slag content on were examined.

In reactor furnace, due to high temperature and high pressure, data can be measured only near the furnace wall. In this paper, the way to estimate temperature distribution in a reactor furnace using measured data near the furnace walls and to control temperature distribution to the desired temperature distribution was studied. In the estimation, SQP method is employed using measured data near t...
