Low Creep Clay Brick

Introduction

It is a kind of new type refractory brick with features of high load and low creep used for fire wall of roasting furnace, researched and developed by our company who commissioned by Zhengzhou Non-ferrous Metal Research institute Co., Ltd of China Aluminum Corp., its biggest characteristic is to solve the problem of the current refractory materials of low refractoriness under load, low hot modulus of rupture, brick size shrinkage and wall cracks in large in use, and large creep rate at high temperature, meanwhile this new type refractory brick has the best heat conduction in fire wall in use,
