Traditional Ladle Refining Furnace (LRF) is used to de-sulphurize steel, adjust its chemical composition and raise the temperature of molten metal besides as a buffer between the melting and casting equipment. Electrotherm Refining Furnace (ERF™) is specially designed metallurgical equipment to de-phosphorize steel besides performing other processes as done by LRF. It facilitates tapping at a lower temperature, which in turn increases production and refractory life of melting equipment and reduces power consumption, thereby reducing the cost of steelmaking. ERF provides greater flexibility to steelmakers in overall plant operation.
The concept is user-friendly and can produce high-quality structural steel, low alloy steel, and other value-added steels through the Induction Furnace – ERF route using even a very high percentage of sponge Iron / DRI as raw material.
