Product Description
Description For High Alumina Refractory Brick Fire Clay Silica Checker Brick For Steel Furnaces with Low Creep Rate
Refractory Checker Bricks are made from silica,clinker clay or bauxite by mixing, forming, drying, sintering, and proportioning. The checker brick is a kind of heat-exchange capacity, large heat storage area, smooth ventilation, low resistance and other heat-carrying heat storage body, with good volume stability, high temperature creep performance, high density and low porosity and other excellent characteristics.
According to the structure, there are 7, 9, 19, 31 and 37-hole high-efficiency checker bricks, and the materials are silica, clay, high alumina, etc.The size is precise, providing kinds of shapes according to customer's drawing
