Product description
Magnesia spinel brick produced by CH Refractories is a kind of high temperature refractory material with very high temperature resistance. Under continuous high temperature conditions, the properties of the material will not be greatly affected.
Magnesia spinel brick can still maintain good stability under the condition of strong acid, alkali and other corrosive media. This material can be used in harsh environments and will not be damaged by corrosion.
Magnesia spinel brick has high compressive strength and can withstand greater impact force and external pressure. Under high temperature conditions, the compressive strength of the material still shows good stability.
The thermal shock stability of magnesia alumina spinel brick is very good and will not be affected by sudden temperature changes. It can be used in harsh high temperature environment.
Application:
Because magnesia spinel brick has good fire resistance and carbonization, it is also widely used in metallurgy, thermal power generation and other fields.
