High Duty Firebrick

There are more Al2O3 in high duty firebrick aluminum bricks, close to neutral refractory materials, which can resist the erosion of acidic slag and alkaline slag, because it contains SiO2, so the ability of anti-alkaline slag is weaker than the ability of anti-acid slag. In addition, the slag resistance of high aluminum products is also related to the stability of the products in the slag. In general, after high pressure molding and high temperature firing, products with lower porosity have higher slag resistance.
