High Chrome Brick for Sale
Description
High chrome bricks are a special kind of refractory material, whose main components are chromium oxide and alumina. High chrome refractory bricks have excellent refractory properties and can withstand extreme environments such as high temperatures, high pressures and corrosion, so they are widely used in metallurgical, chemical and construction industries.
Features
High temperature stability
High chrome refractory bricks can withstand high temperatures and maintain stable performance for a long period of time, not easy to melt and soften.
Strong corrosion resistance
High chrome firebricks have high resistance to acid, alkali, oxides and other corrosive substances, and can be used for a long time in corrosive environments.
Good abrasion resistance
High chrome refractory bricks have good hardness and abrasion resistance, and can withstand mechanical abrasion and impact.
High density
High chrome bricks have higher density and therefore have better compression resistance.
Low coefficient of thermal expansion
High chrome firebrick has a low coefficient of thermal expansion, which makes it less susceptible to thermal stress and rupture at high temperatures.
Light weight
Compared to traditional refractory materials, high chrome bricks are lighter in weight, making them easier to handle and install.
Application
Iron and steel smelting
High-chrome bricks are mainly used for the lining of iron and steel smelting equipment and the masonry of furnace throat, flue, kiln shell and other parts of thermal equipment, such as blast furnace, converter, electric arc furnace and so on.
Copper refining, zinc refining
High-chromium fire bricks are also widely used in the lining of high-temperature equipments in copper and zinc smelting industries, such as copper oxide smelting furnace, flash furnace, and so on.
Silicon material production
High-chromium refractory bricks are also used for high-temperature equipment lining in the production of silicon materials, such as the hearth and flue of silicon furnace.
Chemical industry
High-chromium bricks can be used in the manufacture of chemical equipment such as reactors, heating furnaces, heat exchangers and other components to withstand high temperatures, corrosion and other harsh environments.
Other fields
High-chromium fire brick can also be used in the lining of high-temperature equipment in the glass and ceramic industries.
