Magnesia Spinel Brick
Magnesia spinel bricks are refractory products made of periclase and magnesia alumina spinel ,which can improve the heat stability of common magnesia brick. The thermal shock resistance of magnesia spinel bricks, and the refractoriness is above 1580℃, with high corrosion resistance to basic melting slag.
1.Excellent heat stability
2.Better anti-stripping performance
3.Excellent Thermal Shock Resistance
4.Good corrosion resistance
5.Good Performance under Thermal and Mechanical Loads
Magnesia Spinel Brick Description
Magnesia spinel brick takes good quality fused magnesite and fused mgo clinker as raw material, formed under high pressure,burned in high temperature. In order to form direct bonded, the SiO2 content in raw materials is best to low, and that the sintering temperature must be raised to about 1700ºC.
The Application Of Magnesia Spinel Brick
Magnesia spinel brick widely used in steel refractories, used for the production of ladle castable material, greatly improve the corrosion resistance of steel lining.
Magnesia spinel brick can be used in the air, without any protective atmosphere, widly used in metallurgy, ceramics, glass, machinery, semiconductor, scientific.
Magnesia spinel brick with good thermal stability, it is mainly used for burning zone and transition zone of cement kiln, also some other industrial furnaces.
