LRF is the furnace in which the quality of liquid steel is improved by refining and heating. The chemical composition and physical properties are responsible for the quality of the steel. Sulphur (S) and Phosphorous (P) are two crucial elements in steel whose proportions need to be controlled to make high quality steel. In LRF, the steel is refined in terms of Sulphur (S) and Phosphorous (P) in the induction route. Additionally, LRF treatment helps float inclusions in steel and removes dissolved gases. All these operations help to produce better quality steel.
