Chrome corundum bricks are characterized by high temperature resistance, abrasion resistance, corrosion resistance and good thermal shock stability. We provide you with high quality chrome corundum refractory bricks and sell them wholesale at factory price. Inform us your requirements, you can also get chrome corundum brick customized service.
Chrome Corundum Brick refers to the refractory products with the content of alumina and Cr2O3 greater than 90% and corundum as the main crystalline phase. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chrome corundum products is better than pure corundum products.
Chrome corundum bricks have good chemical stability, acidic or alkaline slag, metal and glass liquid have strong resistance, mainly used in the furnace bottom, door and cylinder parts, heating furnace slide brick and out of the steel groove brick are used chrome corundum bricks.
The normal temperature compressive strength of chrome corundum bricks is generally >150MPa, and its strength is significantly higher than that of corundum bricks.
This is due to the products in the firing process, its particles and particles, particles and fines are formed between the AL2O3-Cr2O3 solid solution.
The solid solution links the particles and fines together like a bridge, which improves the strength of the product.
Chrome corundum bricks have a relatively dense grain structure, which is conducive to reducing heat conduction and thermal expansion, and improving the thermal shock resistance and mechanical strength of the material.
Chrome corundum bricks have high hardness, good wear resistance, and can withstand the impact and abrasion of high-speed flow of gas and liquid.
Chrome corundum bricks have good corrosion resistance and can withstand the erosion of acid, alkali, salt and other corrosive media.
Good thermal shock stability
Chrome corundum bricks have good thermal shock stability, can withstand instantaneous thermal shock under high temperature, and are not easy to occur thermal cracks and thermal shock damage.
Chrome corundum bricks have a long service life and can operate stably for a long time under high temperature, high pressure and strong corrosive environment, which reduces the maintenance and replacement cost of the equipment.
High Temperature Furnace
Chrome corundum bricks can withstand thermal shock and abrasion at high temperatures, and are suitable for lining and insulating high temperature furnace chambers.
Heat Treatment Furnaces
Chrome corundum refractory bricks are able to withstand thermal shock and abrasion at high temperatures, and are suitable for the lining and insulation of various types of heat treatment furnaces, such as quenching furnaces, annealing furnaces, even heat furnaces and so on.
Coal Gasification Furnace
Chrome corundum bricks have good corrosion resistance and can withstand high temperature, high pressure and erosion of corrosive gases in coal gasification furnaces, and are suitable for the lining and heat insulation layer of coal gasification furnaces.
Chrome corundum firebricks have good resistance to high temperature, abrasion and thermal shock stability, suitable for sintering furnace lining and heat insulation layer.
Chrome corundum bricks have good corrosion resistance and can withstand the erosion of acid, alkali, salt and other corrosive media in the chemical reactor, and are suitable for the lining and heat insulation layer of all kinds of chemical reactors.
