Present Trend on Refractory uses for Reheating Furnaces

Abstract

The Reheating Furnaces play an important role in proce-ssing steel and its alloys for the production of finished products. The steel ingots, slabs or bars are heated in these furnaces to an even temperature throughout their body so that they can be properly rolled or pressed into strip, plate, rod, angle or any other shape as required. The temperature generally varies from 1130° to 1425°C, depending upon the quality of the steel, size of the product, etc Although the consumption of refractories per tonne of steel for the reheating furnaces Is not much, the object for the consumers is to have better and better refractories for getting longer life with less number of shutdowns for intermediate repairs. This will ultimately lead to reduced cost for refractories.
