What are the dimensions of refractory bricks?   Refractories are generally divided into two categories, namely unshaped refractories and shaped refractories. Unshaped refractories, also known as castables, are mixed powder granular materials composed of a variety of aggregates or aggregates and one or more binders. It must be evenly mixed with one or more liquids and has strong fluidity. Form...

What is spray refractory ? Refractory spray paint are amorphous Refractory that are constructed by mechanical spraying using pneumatic tools.   A bulk material made of clay clinker as raw material, mixed with various micro-powder additives and cement as binder, as the protection layer of the inner surface of blast furnace and hot blast furnace shell, and the working lining of blast furna...

What is castable refractory?   The Refractory are divided into Refractory and unshaped refractories, which mainly include various refractory bricks and precast refractory parts, while the non-shaped castable is classified according to its material, combination, construction method, use and characteristics, refractory castables are Refractory.   The castable is a kind of granular and...

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...
