Product Description
Magnesia chrome brick is mainly made from sintered magnesia and chrome-oxide, by high pressure shaping and chrome-oxide,by high pressure shaping and high temperature firing.According to different requirements the contents of the Cr2O3 can be changed. The product has good specifications for the shock resistance and high temperature performance. It's characterized by the small thermal expansion.The good thermal shock resistance and slag resistance.It is widely used for many industrial furnaces and kilns such as cement kilns,open-hearth furnace and melting furnace for nan-ferrous metals.Extra high temperature firing direct bonded,rebounded,rebounded and semirebonded magnesia-chrome brick,which are made from purity material all or part of the material that is synthesizeed through fusion,pressed with fine ingredients and high pressure and sintered by extra high temperature.
