Specifications
Refractory Bricks magnesia chrome bricks are mainly made from sintered magnesia and chrome-oxide after high pressure shaped
Refractory Bricks magnesia chrome bricks are mainly made from sintered magnesia and chrome-oxide, by high pressure shaping and high temperature firing. According to different requirements, the contents of the Cr2O3 can be changed.
Features;
Magnesite-ferrum spinel brick and synthetic magnesite-ferrum-alumina spinel brick are made of high purified magnesite clinker and ferrum-alumina spinel clinker at strictly controlled temperature and sintered atmosphere,which enables the product to have good flexibility and temperature vibration. The performances of attaching kiln wall and corrosion resistance are better good quality magnesite chrome brick.the product is update product for lining of large dry cement rotary kilns.
