Corundum firebrick is a kind of refractory brick products with excellent performance, which is suitable for all kinds of high temperature, high pressure, corrosion and other harsh environments.
Corundum bricks are refractory bricks with Al2O3 content of more than 90%, made with corundum as the main crystalline phase. Corundum Fire bricks are chemically stable, with a hardness of up to 9 on the Mohs scale, a high melting point, and strong resistance to acidic and alkaline slag. Corundum refractory bricks are often used in industrial furnaces where the temperature is higher than 1700℃ or the pressure is up to 340MPa.
Corundum bricks can also be divided into sintered corundum bricks and electrofused corundum bricks. Sintered corundum bricks can be made of sintered alumina and electrofused corundum as raw materials or bauxite clinker with high alumina/silicon oxide ratio and sintered alumina, using the sintering method. The products have excellent characteristics such as high strength, high stability, erosion resistance and thermal shock resistance, and are widely used in high temperature and high pressure process equipment.
Fireramo corundum bricks can withstand high temperatures up to 1800°C (3272°F), making them ideal for use in industrial furnaces, kilns and other high heat applications.
Corundum Fire bricks are very stable at high temperatures and can withstand long periods of high temperature use without deformation or cracking.
Corundum brick have high room temperature compressive strength up to 340MPa, capable of withstanding high loads and impacts.
Corundum bricks have good chemical stability and can effectively resist the erosion of acidic or alkaline slag, metal and glass liquid.
Corundum fire bricks have high hardness and abrasion resistance, which can resist all kinds of abrasion and impact at high temperature and prolong the service life of the equipment.
Corundum bricks have excellent insulating properties, which can help reduce heat loss and improve energy efficiency in industrial processes.
Corundum refractory bricks are suitable for a variety of high temperature, high pressure, corrosive and other harsh environments. They are widely used in iron and steel, non-ferrous metals, glass, ceramics and other fields.
In the process of iron and steel smelting, corundum refractory bricks can be used for masonry blast furnace, hot blast furnace, electric furnace roof and other key parts, which can withstand high temperature, high pressure, acidic or alkaline slag erosion, and at the same time has high wear resistance and thermal shock stability.
In the smelting process of copper, nickel, lead and other non-ferrous metals, corundum refractory bricks can be used for masonry smelting furnaces, holding furnaces, refining furnaces and other key parts, which can provide good refractory performance and high temperature stability.
In the process of glass melting, corundum bricks can be used for masonry of key parts of glass kiln, such as feeding opening, swan piece, etc., which can withstand high temperature, high pressure, acidic or alkaline slag erosion.
In the ceramic firing process, corundum fire bricks can be used in the lining of masonry kilns, providing good refractory performance and high temperature stability, as well as high abrasion resistance and thermal shock stability.
In addition to the above application scenarios, corundum refractory bricks can also be used for high temperature kiln linings in the petrochemical and cement industries, as well as in critical areas such as nuclear reactor fuel element casings in the nuclear industry.
