Magnesia chrome brick for sale is generally produced by sintered magnesia and refractory chromium ore as raw material, refractory grain for silicate combination, the domestic said magnesia chrome brick, generally refers to fired into the ordinary magnesia chrome brick, referred to as magnesia chrome brick.
The refractoriness of magnesia chrome brick is greater than 2000℃, the softening temperature under load is generally above 1550℃, the high temperature volume stability is good, the resistance to rapid cooling and rapid heating is stronger than magnesia brick.
