Magnesia-dolomite bricks are made from qualified magnesite and dolomite as the raw materials that are processed through secondary-burning (calcinations, fine grinding, briquetting, dead burned). The MgO/CaO ratio is taken as the kind of Mag-dolomite brick or unshaped monolithics in accordance with customers requirement. Pitch or paraffin impregnation pressed by vacuum is needed after burned under high temperature. They have the features of high temperature performance and resistance to slag and widely used in the secondary refining vessels as VOD, AOD; permanent linings or bottom of convertor; ladle and also the cement kiln.

Definition of Magnesia-Dolomite Brick

Magnesia-dolomite brick is a kind of basic refractory product with the high content of magnesia oxide. The  mass ratio of CaO and MgO is less than1.39 , its production process is similar to the dolomite brick. It mainly used in steel refining furnace, iron-melting furnace and cement kiln.

Application of Magnesia-Dolomite Brick

1, Basic open-hearth furnace, electric furnace bottom and lining

2,Converter furnace permanent layer.

3,Nonferrous metal melting furnace

4,High temperature tunnel kiln

5,Cement rotary kiln

Advantages of Magnesia-dolomite Brick

Compared with common fire brick, magnesia brick with higher refractoriness, strong resistance to alkali, and high strength, which is an ideal fire brick for high temperature kiln.
