Silicon Mullite brick

Description

Silicon Mullite brick

 
 Silica mullite Combonded Brick is composed of two parts: working layer and insulating layer, which is a new type refractory brick. Working layer of high-quality aluminum bauxite, silicon carbide as the main raw materials, thermal insulation layer using low thermal conductivity of the aluminum silicate materials, through high-pressure molding and special firing process and the production, and the combination of the two parts of the surface jagged form a composite brick.  
 The working layer of silica mullite combonded brick has the characteristics of strong abrasion resistance, High anti-erosion ability, strong anti-spalling performance and not suitable for hanging kiln skin at high temperature.Thermal insulation layer has the characteristics of low thermal conductivity, can achieve lower carcass temperature, Energy saving dual function, can greatly prolong the life of Rotary kiln,is a new type of dry cement kiln Cooling belt, The transition zone ideal lining material.
