Magnesia chrome bricks for flash furnace

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

Application:

Magnesia chrome bricks are used as linings of reaction tower for flash furnace copper smelting.

　　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.
