Magnesia-chrome bricks are widely used in industry, construction and other fields because of their high-quality properties such as heat resistance and pressure resistance. There are also several different types of magnesia-zirconium bricks. There are three main types of magnesia chrome bricks:
1. Burning magnesia-chrome bricks:
The fired magnesia-chrome brick is made of high-quality magnesia and chrome ore fine ingredients. The content of Cr2O3 is adjusted according to different needs. The product has good thermal stability and high temperature performance.

2. Directly combine magnesia chrome bricks:
Directly combined magnesia-chrome bricks use chrome ore with low impurity content and high-quality high-purity magnesia as raw materials, which are formed by high pressure and fired at high temperature above 1700℃. Good high temperature performance and strong slag corrosion resistance. Resistant to cement clinker erosion. Widely used in non-ferrous metallurgical furnaces and cement rotary kilns.
3. Semi-recombined magnesia-chrome bricks and recombined magnesia-chrome bricks
Semi-rebonded magnesia-chrome bricks and re-bonded magnesia-chrome bricks use part or all of fused sand (electrofusion synthetic sand) as raw materials, fine ingredients, high pressure molding, ultra-high temperature calcination, good particle bonding, high product strength, and stable volume It has good performance and is widely used in RH, VOD, AOD and other out-of-furnace refining devices, non-ferrous metallurgical furnaces, etc.
