high refractoriness Brick brief introduction
Magnesite Carbon brick is a kind of basic refractory which is made from magnesite, graphite as raw material, resin as binder, with high pressure moulding and low temperature treatment.
As one kind of compound refractories, it make magnesite good slag erosion risistance and graphite high thermal conductivity and low dilatability mixed together. Thus BOF Brick has features of high refractoriness, good thermal shock resistance,erosion resistance, and has good performance in I&S industry, including BOF, EAF, LF.
basic refractory brick series have the advantages of good performance, long life and low cost. And long supply experience can make sure that we can give our customer total solutions
Alumina Magnesia Carbon brick has same production process, the main raw materials are fused alumina or bauxite, so it has better strength and refractoriness under load, but the slag resistance is not as good as magnesia Carbon bricks.
Magnesia Alumina brick(HLML)is made of high quality magnesia and alumina It has good performance under high temperature and high thermal shock resistance. It is widely used non-ferrous furnaces.
Magnisia-Alumina Spinel brick(HLMLJ)is made of high quality magnesia and synthetic magnesia alumina spinel clinker. It has good high-temperature performance, thermal shock resistance and strong slag resistance. The main applications are transition zone in cement rotary kilns glass tank regenerators and lime kilns.
