Description

Product Description

Magnesia spinel brick is a kind of basic refractory material which is manufactured by using magnesia and alumina oxide powder or bauxite as raw materials. The thermal shock resistance of magnesia alumina brick is better than that of magnesia bricks, and the refractoriness is above 1580°C, with high corrosion resistance to basic melting slag. It is mainly applied to the top of steel making open-hearth furnace and EAF, high temperature tunnel kiln, large-scale cement rotary kiln and non-ferrous metal smelting furnaces,etc.
Magnesia hercynite brick was prepared with hercynite as raw materials. The application results showed that the cement kiln coating formed rapidly and stability when using magnesia-hercynite brick. The magnesia-hercynite brick had low thermal conductivity and long service life, and its overall performance was better than magnesia-chrome brick. The magnesia-hercynite brick could satisfy the chrome free requirement of burning zone of large-scale rotary kiln.
