Arc Furnace: Ladle Refining Furnace (LRF)
Usually small furnaces are Spout Type and Furnaces above 20 Tons are EBT Type, where slag free metal is tapped. EAF route is mainly for Plain Carbon & Alloy Steel making for automobile industries and also high alloy steel grades. The heat after tapping is processed at LRF for final chemistry and temperature. After LRF the heat is transferred to VD for removal of Hydrogen and other impurities. After VD operation trimming alloy adjustment may be done and heat is sent for casting to CCM. The Caster is most important area which can improve or deteriorate the steel quality related to physical and Structre of steel. For Stainless Steel VOD or AOD can installed in line with EAF.
SMRC's Design solutions for Ladle Refining Furnace are increasingly being installed in basic oxygen plants as well as in electric arc furnace melt shops. SMRC as solutions for every ladle furnace application. To cutomised design SMRC's ladle furnaces fits in tightest space requirements and fulfill both the requirements of special steel plants with long and intensive metallurgical treatments as well as high performance and short time treatment cycles in BOF steel plants. In any case special attention is paid to ensure easy and low maintenance requirements in order to guarantee long and trouble free operation.
