DESCRIPTION

In recent years, magnesia-chrome refractories have been widely used in high-temperature kiln furnaces such as non-ferrous smelting furnaces, molten steel refining furnaces and cement rotary kiln,etc.

 

Magnesium-chromium ramming material is mainly used in direct contact with molten material, so it is required that the granule and powder materials must have high volume stability, compactness and erosion resistance.

 

Features:

It has good refractoriness under load, high temperature strength, corrosion resistance, thermal shock stability, low thermal conductivity and good use effect, and can extend the service life of the product.
