Ladle Refining Furnace (LRF) was introduced in the line of steel melting shop for different purpose.

Initially with the help of Oxygen Lancing inside the liquid metal in the LRF, Carbon is reduced to a desired level so it is also called Decarboriser. Facility of Inert Gas Purging ensures homogeneity as well as reduction of entrapped gas in the liquid metal. Different alloys are added in the process to maintain required chemistry of the metal before taking it into the solid form.

LRF is also used as a holding furnace in case casting sources required some attention before casting of the liquid metal. Liquid metal can be taken in LRF from any melting source to process the metal in a different station with the short circuiting arrangement by means of electrodes i.e. by arcing on the surface of the liquid metal.
