Electrotherm (Ladle) Refining Furnaces – …

Electrotherm Refining Furnace (ERF™) is specially designed metallurgical equipment to de-phosphorize steel besides preforming other processes as done by LRF. It facilitates tapping at lower temperature, which in turn increases production and refractory life of melting equipment and reduces power consumption, thereby reducing the cost of steel making.

Ladle Refining Furnace | Secondary Metallurgy | …

Ladle Refining Furnace Large ladles are used in most metal-melting operations to transfer molten metal from melting furnaces to refining or pouring stations. The LRF also acts as a buffer between the steel making furnace and the continuous caster, reducing casting costs and allowing greater flexibility in steel making operations.
