Magnesia Chrome Brick
Magnesia-chrome bricks have good refractory indicators, can effectively block flue gases such as combustion gas and coal flue gas, and can effectively prevent the circulation of flue gas pollutants, thereby achieving the purpose of improving the environment. In addition, magnesia-chrome bricks have high heat absorption, can resist oxidation and corrosion, and can maintain effective heat resistance for a long time.
Magnesia Chrome Brick Description
Magnesia chrome brick is a kind of refractory brick made of magnesia and chrome ore as the main raw material, with calcined magnesia and fused magnesia as the aggregate, and magnesia-chrome ore clinker as the binder. It has good thermal shock resistance, slag resistance and alkali resistance, and is often used in non-ferrous metal smelting furnaces, cement rotary kilns, and glass kilns.
The Application Of Magnesia Brick
Magnesia chrome bricks have high refractoriness and good resistance to slag corrosion, and are ideal lining materials for rotary kilns. Its application range is very wide, such as cement rotary kiln, lime rotary kiln, chemical rotary kiln, etc. It is suitable for various kilns with an operating temperature above 1500 °C.
Magnesia chrome bricks are a common choice for lining the hearth and walls of electric arc furnaces. The brick is a mixture of magnesia and chromium oxide, which can withstand temperatures of up to 2600 degrees Celsius, making it ideal for electric arc furnaces. The brick provides excellent protection against heat and erosion by molten steel, extending the life of the furnace.
Magnesia chrome brick has excellent thermal shock resistance, mechanical strength and corrosion resistance, and is a kind of refractory brick widely used in ladles. It has extremely low thermal conductivity and low porosity, enabling prolonged contact with steel without degradation. Magnesia-chrome bricks can withstand the temperature of molten steel in the ladle, which can reach more than 1500 °C.
Magnesia chrome brick is a kind of refractory brick with high MgO content, which is widely used in metallurgical furnaces. This kind of brick is suitable for the lining of high-temperature furnaces, which can withstand high temperatures and prevent melting. In blast furnaces, it is used for masonry and tapholes, where it can withstand the high temperatures of the furnace and resist attack by slag and other elements.
Magnesia-chrome bricks are commonly used in glass kilns because of their ability to withstand the extreme temperatures of the furnace. These bricks have high refractoriness, thermal shock resistance and corrosion resistance, making them ideal for lining glass furnace walls. Magnesia chrome bricks help retain heat and provide insulation, allowing for even and efficient heating of the glass.
Magnesia chrome brick is a kind of high temperature and corrosion resistant brick, which is widely used in hot blast furnace.The application of it in hot blast stoves can reduce the wear of the furnace wall, improve the thermal efficiency of the furnace, save fuel and reduce emissions. In addition, magnesia-chrome bricks can also be used for the lining of the combustion chamber and the protection of the furnace wall.
