The fire-proof material used in the cement profession>>>
Direct coupling magnesium
chromium brick
The direct coupling magnesium chromium
brick uses the high quality magnesite and the chromium ore concentrate makes
for the raw material fires the product. This product foreign inclusion few,
fires the temperature high, the high temperature mineral farcies direct
coupling rate is high, It has the intensity high, the anti- etching power
strong, the heat shock stability good and the fine high temperature performance
and is easy to hang the kiln skin the characteristic, Widely used in
large-scale violating the law the cement rotary kiln to fire the belt.
