Details
Magnesia-chrome bricks are composed of magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main component, periclase and spinel as the main mineral composition of refractory products. This kind of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag erosion, excellent thermal shock stability, and has considerable adaptability to acidic slag. The main raw materials for the manufacture of magnesia-chrome bricks are sintered magnesia and chromite. The purity of magnesia raw materials should be as high as possible.
Directly bonded magnesia-chrome brick is a product made of high-purity or sub-high-purity sintered or fused magnesia and chrome concentrate as raw materials. Direct bonding refers to a bond produced by direct contact between solid phase grains. The brick is SiO2<2% high purity sintered magnesia and chromium concentrate as raw materials, through high temperature sintering. The degree of direct bonding of the product varies with SiO2The content decreases and the firing temperature increases.
Magnesia chrome bricks are mainly used in the cement industry and metallurgical industry, such as the construction of the top of the furnace, the top of the electric furnace, the furnace refining furnace and a variety of non-ferrous metal smelting furnace. The high temperature part of the high power electric furnace wall is widely used in the cast magnesia chrome brick, the high erosion area of the refining furnace outside the furnace is widely used in the composite material made of magnesia chrome brick, the high erosion area of the non-ferrous metal flash smelting furnace is widely used in the cast magnesia chrome brick, the composite material made of magnesia chrome brick. In addition, magnesia chrome bricks are also widely used in cement rotary kiln firing zone and glass kiln heat storage chamber and other parts.
