Abstract

PURPOSE: In the smelting process in an arc furnace for the steel manufacture, the stage from the oxidizing refining process to the tapping is divided into two temperature control time zones, namely pre-and post-ferro-alloy charge, and by automatically controlling the temperature of molten steel, the control of the temperature of tapping is facilitated, and the improvement of the operation efficiency is planned.
