Magnesia chrome bricks for RH vacuum degasser

MgO (%)≥40～70;　Cr₂O₃ (%)≥8～20
Cold Crushing Strength (MPa): 40
Refractoriness Under Load 0.2MPa (℃) : 1550～1700

Application:

Magnesia chrome bricks for RH vacuum degasser are mainly used for snorkels, the upper and lower parts of vacuum chamber and circulating tube, considering requirements for smelting clean steel.

　　Magnesia chrome bricks are made from fused magnesia and fused magnesia chrome clinker as main materials, being high pressure pressed and sintered in high temperature, which exhibited good corrosion resistance.
