Sell CN ZS Refractory magnesite bricks

Product Description                                       Â

1. Product Details

Magnesia-chrome brick is a high-level refractory product material ,which containing MgO and Cr2O3 as the main components, periclase and spinel are the main mineral components. This type of brick has high refractoriness, high temperature strength, strong resistance to alka, exnt thermal stability, and certain adaptability to acidic slag. The main raw materials for the manufacture of magnesia chrome bricks are sintered magnesia and chromite. The purity of the magnesia raw material should be as high as possible.Â
