The use of refractory cement in boiler construction is also very large, and refractory cement is also a refractory castable that we need most. Refractory cement is also called aluminate cement. The raw material of aluminate cement is bauxite and limestone. It is made of calcined, with calcium aluminate as the main component, clinker with alumina content of about 50%, and then ground into hydraulic cementitious material, which is also a kind of special cement. The thermal stability of refractory cement is good. The aggregate is almost all clinker. The expansion and the shrinkage of the cement are low. Therefore, the thermal expansion of the masonry is smaller than that of the brick, the temperature stress is relatively small, and the structure is also various. Reticulated, needle-like, chain-like crystalline phase, strong resistance to air temperature, for example, used to cast soaking furnace mouth and furnace cover, the furnace age can be extended to one and a half years; and the fire resistance of refractory bricks and the same The texture of the refractory brick is similar, but because the refractory cement does not have a net more sintering, the initial blasting shrinks larger, so the load softening point is slightly lower than the refractory brick, but as a whole, the refractory cement is still due to the refractory brick.

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.
