The goal of the latest strategy in glass companies is to decrease the cost of production while maintaining or increasing the glass quality. There are several perspective ways leading to this goal: Optimization of the heating system, Modification of the furnace design, or Installing the new advanced control system. Optimization of the heating system can be achieved by installing modern burner sy...

this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

Bottom-blowing, as widely adopted in electric arc furnace (EAF) steelmaking technology, stir the molten bath by blowing inert gas (Ar, N2) from the bottom of EAF to promote fluid flow and uneven metallurgical reaction in the molten bath. However, for eccentric structure design of electric arc furnace, the problem still exists in EBT(Eccentric Bottom Tapping)area. In this study, by the analysis ...

This paper provides results from a series of projects investigating the application of PLS to provide process engineering solutions in the steel industry. These applications involve the prediction of final product quality in a LD converter, the prediction of NOx in a reheating furnace and an analysis of the effects that changing scrap types have on final product quality in an electric arc furna...

Electric arc furnace baghouse dust (EAFD), a waste by-product of the steelmaking process, contains the elements that are volatilized from the charge during the melting (Cr, Pb, Zn, Cu and Cd). The results of leaching tests show that the concentration of these elements exceeds the regulatory limits. Consequently, EAFD cannot be disposed of in ordinary landfill sites without stabilization of the ...

In recent years many different ways have been investigated by steel producers to increase ductility, impact strength and formability of steels. More important ways are steels with very low amounts of inclusion, small size inclusions and modified inclusions. In this study, experiments have been performed on the API-X42 steel produced by the electric arc furnace in Mobarekeh Steel Co. After the p...

Now-a-days it has become quite common to use modern electric heating devices in the place of conventional ones. A stud was conducted to standardize the temperature for the preparation of Pravala Bhasma by using Electric Muffle furnace (EMF) The details are presented in this article.
