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.
