Application field:
Magnesium-chrome brick is mainly used in metallurgical industry, such as building open furnace top, electric furnace top, furnace refining furnace and various non-ferrous metal smelting furnace. The high temperature parts of the wall of the ultra-high power electric furnace are made of magnesia chrome bricks, the high erosion area of the refining furnace outside the furnace is made of magnesia chrome bricks made of synthetic materials, and the high erosion area of the non-ferrous metal flash melting furnace is made of magnesia chrome bricks made of fused cast magnesia chrome bricks and synthetic materials. In addition, magnesium-chrome brick is also used in cement rotary kiln firing belt and glass kiln regenerator chamber and other parts.
Company main products and profile:
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
