1. High quality light aluminum bricks is one of ideal insulating refractory, has high crushing strength, low thermal conductivity, heat preservation performance is good, price is low.It is now widely used in ceramic tunnel kiln, roller kiln, shuttle kiln, kiln wall body, as well as for all sorts of coking furnace and heating furnace of steel industry and other thermal technology equipment, heat treatment of lining material, etc., has a broad market prospect.
2. High alumina brick is divided into three grades according to the alumina content. The alumina content and high temperature resistance of high alumina brick are guaranteed by adjusting the proportion of high alumina and bonding clay, so as to meet different use conditions and requirements.
