What are the types of magnesia chrome bricks for industrial use?

Magnesia chrome bricks are widely used in industry, construction and other fields due to their high quality characteristics such as heat resistance, pressure resistance of magnesia carbon bricks for electric furnaces. There are also several different types of magnesia chrome bricks. According to the requirements of different products, there are three types of magnesia chrome bricks for electric furnaces:

1. Fired magnesia chrome brick:

Fired magnesia chrome bricks are made of high-quality magnesia and chrome ore with fine ingredients. The content of Cr2O3 is adjusted according to different needs. The products have good thermal stability and high temperature performance, and are widely used in cement kilns, nonferrous metallurgy furnaces, etc.

2. Directly bonded magnesia chrome brick:

The direct bonded magnesia chrome brick is made of chrome ore with low impurity content and high-quality high-purity magnesia through high-pressure molding and high temperature firing above 1700 ℃. High temperature performance and strong slag erosion resistance. Resistance to cement clinker corrosion. It is widely used in nonferrous metallurgical furnaces and cement rotary kilns.

3. Semi rebonded magnesia chrome bricks and rebonded magnesia chrome bricks

The recombined magnesia chrome brick and the recombined magnesia chrome brick, using part or all of the electro fused sand (electro fused synthetic sand) as raw materials, fine batching, high-pressure molding, ultra-high temperature calcination, good particle bonding, high product strength, good volume stability, are widely used in RH, VOD, AOD and other secondary refining devices, nonferrous metallurgy furnaces, etc.
