high alumina silica refractory bricks high temperature fire brick for sale

Description:

Spinel is the magnesium aluminum formulation of the larger spinel group of minerals. Melting point of Magnesia Spinel is 2135 C, and Magnesia Spinel has very high, excellent refractoriness. Magnesia Spinel refractory bricks possess high-melting point, high chemical inertness against both acidic and basic slags, low expansion values at elevated temperatures and widely used in zones where there is a big temperature change, cement rotary kilns, vacuum induction furnaces, regenerators of glass tanks, lime kilns, continuous casting tundishes, degasser snorkels and lances. The main advantages of using Magnesia Spinel bricks are;

• Very high, excellent refractoriness.
• Low thermal expansion coefficient.
• High resistance to thermo-mechanical stress.
• High resistant to corrosion and changes in kiln atmosphere.
• Low content of secondary oxides.
• Elimination of chromite.
