Fused Magnesia chrome Brick
The fused cast magnesia chrome brick is a refractory product obtained by electrofusion and casting of magnesia and chrome ore. It is characterized by large pores and isolated, and the product is dense, high in strength, corrosion resistant and sensitive to temperature changes. The chemical properties of magnesia-chrome bricks are alkapared with magnesia bricks and chrome bricks, the thermal shock resistance is good, the volume is stable at high temperatures, and the load softening temperature is high.

Magnesia chrome brick is an alkaactory product, which is made of periclase and magnesia chrome spinel, and is fired at 1600~1800 °C in an oxidizing atmosre. It can also be made into non-burned brick by chemical bonding agent such as water glass.
According to the raw materials and process characteristics of the products, it can be divided into silicate-bonded magnesia-chrome bricks, direct-bonded magnesia-chromium bricks, re-combined magnesia-chrome bricks, semi-recombined magnesia-chrome bricks, pre-reacted magnesia-chrome bricks Casting magnesia chrome bricks.
The magnesia chrome brick can be used in vulnerable parts of steelmaking electric furnace, RH, DH vacuum degassing device, secondary refining slag s such as VOD, LF, ASEA-SKF, AOD, steelmaking converter, cement rotary kiln and glass melting Kiln regenerators, etc.
Zhengzhou Huachen Refractory Co.,ltd was founded in 2003, Headquarter is located in Zhengzhou city, which is the capital of Henan Province. Henan province is located in the center of China. Zhengzhou is the center of politics and economy and traffic center in middle of China. Zhengzhou as the staring port of One Belt and One Road,plays an increasingly important role in the international trade.
Since established of the company, we are focusing on producing research and development of refractories and raw materials, especial the fused cast block and the Magnesia series bricks and materials. Now we have two plant, one produce the fused cast blocks, like AZS 33#.36#,41#. the other plant produce the MgO2 series bricks and Al2O3 series bricks, like Magnesia brick, Magnesia chrome brick, Mg-Al spinel brick, high alumina brick and fire clay bricks ...
