Magnesia chrome bricks are made from sintered magnesia, fused magnesia, and fused magnesia-chrome as raw materials, through high pressure molding, drying and high temperature firing.
Magnesia chrome bricks are featured with high bulk density, good slag resistance, strong erosion resistance, high temperature volume stability, good thermal shock resistance. Magnesia chrome bricks refractoriness is more than 2000℃, its refractoriness under load is generally above 1550℃.
Application:
1.Cement industry: cement rotary kiln burning zone.
2.Metallurgical industry: refining ladle permanent layer, electric furnace top, and other kinds of non-ferrous metal smelting furnace.
3.Others: Lime kiln or other high temperature furnace linings.
Magnesia Chrome brick shapes can be customized according to drawings.
