Andalusite Fire Proof Brick For Hot Blast Stove Wall and Checker Brick
The production process of andalusite refractory bricks : The above raw materials are prepared according to the formula proportions, and then the mullite powder, andalusite fine powder and sillimanite fine powder are mixed into the mixer, Then add clay and 2% of the total weight of raw water to mix and add silicon micro powder for mixing. The brick is pressed into brick, and the bricks are sintered into the kiln after being dried, that is to say, finally they are fired into andalusite refractory bricks.
The raw material of andalusite firebrick is: 300 kilograms of mullite powder, 100 kilograms of andalusite powder, 50 kilograms of sillimanite powder, 50 kilograms of clay, and 30 kilograms of silicon powder.
1.High temperature resistance, wear resistance, corrosion resistance.
2. Good thermal shock resistance .
3. Low creep rate.
4. High softening temperature under load.
5.Can reduce the harmful impurities.
6. Good resistance to heat falling out.
Andalusite Fire Proof Brick Application
