Difference between converter steelmaking and electric arc furnace steelmaking

Converter steelmaking is the process of converting molten iron from the blast furnace into oxygen. The furnace body can rotate. The steel plate is used as the shell, and the refractory material is used as the lining. During converter steelmaking, there is no need to heat the molten iron, because the molten iron itself is high temperature, and the oxidation reaction of heating continues inside.

Electric arc furnace's future technical direction

With the goal of "high efficiency, low consumption, green and intelligent", steel enterprises need to select appropriate electric furnace type and production technology. The raw material of converter process is mainly liquid molten iron, the raw material of electric furnace process is mainly solid scrap, and the final product form is liquid steel. The different transformation of physical and chemical forms determines the different control methods.

Electric arc furnace's slag-free tapping technology

In the late 1970s, Krupp Stahl AG developed a simple steel slag separation technology, that is, according to the siphon principle, the original horizontal tapping hole of the electric arc furnace​ was changed to an inclined type. The inner end is buried in the molten steel to a certain depth, and the outer end of the furnace is higher than the molten steel level.
