Magnesia chrome bricks
metallurgy industry furnace , electric furnace roof, Mixer etc.
RH, VOD, AOD, and other industry
Magnesia chrome bricks features:
Low porosity, high compressive strength, flexural strength ofhigh pressure, good bulk stability;
Good thermal shock resistance, anti-spalling
Easy-to-skin hanging in the kiln, and low thermalconductivity;
High temperature of refractoriness under load
Ultra-high-temperature firing, high direct binding rate, highrefractoriness and corrosion resistance
Strong resistance against alkaline substances, the acidresistance better than the magnesia refractories
Magnesia chrome bricks application:
metallurgy industry of open-hearth furnace top , electricfurnace roof, Mixer etc.
RH, VOD, AOD, and other refining installations;
Non-ferrous metallurgical furnace, vacuum treatmentequipment;
Building materials , glass furnace regenerator; cement rotarykiln calcination etc.
