Magnesia Brick

Magnesia bricks

Application
It is mainly used for basic open hearth furnace, electric furnace bottom and wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and lining of cement rotary kiln, furnace bottom and wall of heating furnace, lattice brick of regenerative chamber of glass kiln, etc.

Production process
Sintered magnesia brick is made of magnesia brick as raw material, after crushing, batching, mixing and molding, it is fired at a high temperature of 1550 ~ 1600℃, and the sintering temperature of high purity products is above 1750℃.Unpoured magnesia brick is made by mixing, forming and drying with appropriate chemical binder in magnesia.Magnesium bricks • Instructions for use

Magnesium brick is made of more than 87% sintered magnesite as raw material, with magnesite as the main crystal phase in the products, and alkaline refractory materials combined with silicate.Because its matrix binding component is mainly CMS-M2S system, its softening temperature under load is not high, and its thermal shock resistance is poor, therefore, its application scope is relatively narrow.Some important properties of magnesia brick mainly depend on the properties of raw materials, the mineral composition and microstructure formed in the product, and are closely related to the density of the product.
