Shaped refractory brick is a new type of special refractory material developed on the basis of traditional ceramics and general refractory materials, so it is also called high temperature ceramics or high temperature materials. It includes high melting point oxides and high melting point non-oxides and the resulting metal ceramics, high temperature coatings, high temperature fibers and reinforcing materials.
One of the high melting point non-oxide often called refractory compounds, which includes carbides, nitrides, borides, silicides and sulfides. There are cement kiln firing belt, transition belt and glass kiln heat storage chamber lattice body can not be separated from the key materials, alkaline refractory material is good or bad, is to affect the service life of the kiln, one of the decisive factors of production efficiency.
Therefore, each country without exception to the special type of refractory brick research and development, production as the main direction, in order to reflect its comprehensive level and strength. Compared with ordinary refractory bricks, special type refractory bricks have long service life, high purity, strong refractoriness, resistance to sunlight, beautiful appearance and strong water absorption. Therefore, specialized refractory bricks occupy most of the market.
In the material, profiled refractory bricks compared with ordinary refractory bricks: special profiled brick selection to fine, raw materials, and high grade, high purity, good texture of the raw materials used are almost synthetic or minerals through mechanical, physical, chemical methods of purification of chemical materials, and rarely directly refer to the mineral raw materials.
The material has more excellent thermal properties, electrical properties, mechanical properties, chemical properties. Therefore, the scope of use is more extensive than ordinary bricks.
