Professional Refractoriness Degree Magnesia Fired Brick Magnesia refractory Brick for RH furnace

RH furnace refractory configuration

The part of the hot bending pipe is the waste flue gas passage of the RH vacuum tank, which is not in contact with molten steel and slag, and the damage to the refractory material is small. The main reason for the damage is mechanical action. The stress generated by temperature fluctuations and the erosion and erosion caused by hot gas flow liquid slag, etc

The direct-bonded magnesia-chrome brick XBM Ge-16 with good thermal shock stability and corrosion resistance is used for working lining; the lightweight high-alumina brick XLG-1.0 is used for thermal insulation lining; calcium silicate insulation board is used for thermal insulation lining.

Observation hole. Magnesium-chrome castables are used for the top gun, and corundum-spinel castables or fired high-quality magnesia-chrome bricks are used in the manhole.
