In the traditional smelting process, the
existence of the reduction period shows the characteristics of EAF
steelmaking. The main difference of modern EAF smelting process is that
the reduction period is moved outside the furnace.
The main tasks of the reduction period:
Deoxidation to the requirement---- deoxidation;
Desulfurization to a certain value----desulfurization;
Adjust the temperature----adjust the temperature.
Among them: deoxidation is the core, temperature is the condition, and slag forming is the guarantee.
