How to improve the thermal shock resistance of high alumina bricks?   Using grade 1 bauxite clinker and fused white corundum powder as raw materials, adding an appropriate amount of expansion agent, forming and heat treatment at 800 ℃, high-alumina bricks with good thermal shock stability can be obtained Using grade 1 bauxite clinker and fused white corundum powder as raw materials, adding an...

What is the composition of fused zirconium corundum brick？ The composition of zirconium corundum brick is in the triangle of Al2O3-Zro2, 3Al2O3-2S02. Therefore, the final crystallization of the melt should be these three phases and converge at the Y point. exist During cooling, initially in ZrO2-Al2O3. In the binary composition system, baddeleyite (ZrO2) and corundum (Al2O3) crystals are precipita...

What characteristics should blast furnace gunning material have?   1 The original furnace refractory material of blast furnace is fully utilized, and the consumption of refractory material is reduced. 2. The gunning operation time is short, the intermediate repair time is saved, and the blast furnace operation rate is improved. ) significantly reduces the heat that needs to be taken away...
