Use fo Castables and high alumina refractories for lining reheating furnaces

Reheating furnaces are used for intermediate heating of steel blooms, ingots, billets and slabs during their final finishing process. These furnaces are of two types i.e. batch type and continuous type. Batch furnaces are gene-rally simple box type used for heating prior to forging and shaping. Such furnaces should be able to withstand required operating temperature, frequent heating and cool-ing and abrasion due to stock handling.
