High aluminum brick is a kind of refractory material widely used, the main chemical composition is alumina (Al2O3), usually used in a variety of high temperature industrial kiln lining, flue, cooling wall and other parts. According to different uses and chemical composition, high alumina bricks can be divided into a number of types, the following is to introduce several common high alumina bricks:
1, standard high aluminum brick
mainly composed of alumina and silicate materials, has high corrosion resistance and thermal shock resistance, is widely used in steel, glass, cement and other industries.
2, light high aluminum brick
light high aluminum brick is mainly made of foam ceramic, alumina, silicate and other materials, lighter than the standard high aluminum brick, low density, but has excellent thermal insulation effect, mainly used for furnace top, flue and other parts.
3, curing high alumina brick
a certain amount of clinker is added in the production process, so that it experiences a certain curing process before use, so as to improve its physical properties and fire resistance, widely used in coke oven, converter and other high temperature industrial kiln lining and flue.
4, siliceous high alumina brick
siliceous high alumina brick is a kind of high alumina brick based on alumina and silicate, adding an appropriate amount of quartz, bentonite and other materials made of high alumina brick type. With high fire resistance and corrosion resistance, it is widely used in iron and steel smelting, copper smelting and other industries.
5, mullite high alumina brick
made of mullite, alumina and other materials, mullite has better expansion at high temperature, making high alumina brick has good thermal shock resistance and heat insulation performance, mainly used in metallurgy and ceramics and other industries.
6, high aluminum core fired brick
high aluminum brick Al2O3 content of more than 90% of the brick, often used in industrial furnace erosion sites, such as electric furnace, converter, cement rotary kiln, etc.
In short, different kinds of high alumina bricks have different application scenarios and physical properties, manufacturers need to combine customer demand, use environment and performance characteristics of high alumina bricks themselves to choose.
