Effect of Heating Unit Lining Warm-Up Regimes and Refractory Storage Duration on Refractory Lining Life

摘要

Measures are developed for improving heating unit (converter) lining life. This task is resolved by studying the mechanism of heating unit lining breakdown during heating and cooling, changes in thermophysical properties of refractories of different composition, and also refractories impregnated with copper-nickel matte. Lining drying and heating schedules are studied. Measures developed on the basis of results obtained with proving under industrial conditions make it possible to increase converter lining life by 25 - 30% without special material consumption.
