Product Description

Magnesia chrome brick is a type of refractory brick. Magnesia chrome brick is made by combining (MgO) and chromium trioxide (Cr2O3) in a high-temperature firing process. The resulting brick is highly resistant to corrosion, thermal shock, and wear. Magnesia Chrome Brick is mainly used in the metallurgical industry, such as the construction of flat-bottom furnace roofs, electric furnace roofs, refining furnaces outside the furnace, and various non-ferrous metal smelting furnaces. The content of chrome can be adjusted according to the customer’s requirement.

Features

Good thermal shock resistance

Excellent slag wear resistance

Good cold compression strength

High temperature resistance and high fire resistance

High-grade chrome ore raw materials

Lower impurity content
