A fire brick is a block of refractory ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces.
refractory fire brick characterized by good mechanical property at
high temperature
Low thermal conductivity
high stength
refractory fire brick is made from high-grade and high purity refractory powers and materials. During the process of production, organic and multiple filling materials are injected according to the required proportion.
In addition, we also produce a various of refractory bricks based on the customer’s requirement, such as fireclay bricks, high alumina bricks,Mg-C bricks, Mg-Cr bricks, corundum bricks and so on.
Well come your detailed inquiry.
