Abstract

This article is focused on the processes in the second step which is about melting the raw materials and achieving the desired chemical analysis and temperature of the steel required for the third step in steel production-Casting and Solidification. The temperature of the electrodes (mainly the cathode) reaches 2700–3300°C.Ionization occurs due to the high temperature of the arc. That's way, good electrical conductivity occurs between the electrode. After the liquefaction process was completed at the specified time and the furnace temperature was sufficient after the metal was liquefied, a certain amount of aluminum alloy was added to the furnace to improve the fluidity of the liquid metal, and the liquid metal sand was poured into a clay mold.
