85%-92% Dead burned magnesiais mainly made of natural magnesite ore with 46% content, which is calcined by high temperature kiln at about 1400℃-1800℃.

Application: Dead burned magnesia is mainly used as raw material for making magnesia bricks and producing amorphous refractory materials. The finished products are used in steel making, electric furnace bottom and ramming furnace.

The main varieties of dead burned magnesia have 85%-92% content, these varieties are mainly selected 46.5% to magnesite, sintered kiln calcination heating to 1400-1800 ℃ Mg(CO3) completely decomposed, generating magnesite, become hard reddish-brown dead burned magnesium, it has a high refractorability. Dead burned magnesia is mainly used for magnesia brick, steelmaking, electric furnace bottom and ramming furnace lining.

94%-98% Dead burned magnesia is made of natural super-grade magnesite ore. It is made by light burning, fine grinding, pressing balls and calcining in ultra-high temperature oil shaft kiln. It is a high-quality raw material for brick making and uncertain refractories.

The main varieties of dead-burned magnesia have 96% content and 97% content. These kinds of dead-burned magnesia mainly use magnesite ore with more than 46.5% of the content. When heated to 1400-1800°C by sintering kiln, Mg(CO3) is completely decomposed., to generate periclase, which becomes hard reddish-brown dead-burned magnesia, which has high refractoriness. Dead burnt magnesia is mainly used for magnesia bricks, steelmaking, electric furnace bottom and ramming furnace lining.

Fused magnesiais a general term for the products of magnesia raw materials such as magnesite after high temperature treatment to the degree of sintering. The main varieties have 94%-98% content. Using high-temperature equipment such as shaft kilns and rotary kilns for one-time or two-step calcination, the magnesite fired with natural magnesite as raw material is called sintered magnesite; the magnesite is smelted with electric arc furnace as raw material to achieve molten state cooling The final form is called fused magnesia; the one made by extracting magnesia from seawater is called seawater magnesia. Magnesia is one of the most important raw materials for refractory materials, and is used to manufacture various magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks, magnesia-chrome bricks, ramming materials, furnace repair materials, etc.

Caustic calcined magnesia (CCM) is reactive form of MgO produced by firing magnesite at temperatures between 600°C - 1000°C. Mainly used in: Agricultural applications, Hydrometallurgical processes, Pulp and paper, Construction and Sorel cement, Chemicals and pharmaceuticals industry, Environmental applications, Glass industry.

Light burnt magnesia ball is made of magnesium oxide as the main raw material, adding water and binder at the same time, stirring and pressing under high pressure.

Light burnt magnesia ball is mainly used as the composition regulator of converter slag splashing. Because the slag splashing requires proper viscosity and fire resistance, reasonable slag composition is the key to realize the slag splashing.

Generally slag can not be sprayed directly to protect the furnace. A certain amount of magnesia ball is added to adjust the slag. Since MgO is a kind of high melting point mineral, the melting point is 2800℃, the increase of MgO content in slag will increase the viscosity of slag and improve the fire resistance.

The slag is easy to combine with the lining, forming an effective slag protection layer on the lining, improving the life of the lining and reducing the consumption.
