Alkaline refractory brick is a kind of special refractory material, mainly used in alkaline environment of high temperature equipment and kiln. What about alkaline firebricks? Here are some common alkaline firebricks.
1. Magnesia-chrome brick
Magnesia chrome brick is mainly composed of magnesia and chrome oxide, which has good alkali corrosion resistance and high temperature resistance.
2. Silicon carbide brick
Silicon carbide brick is mainly composed of silicon carbide, silicon oxide and other substances, has excellent corrosion resistance and high temperature stability.
3, calcium oxide brick
Calcium oxide brick is mainly composed of calcium oxide, alumina and other substances, has good alkali corrosion resistance and high temperature resistance.
4. Silicate brick
Silicate brick is mainly composed of silicate and other materials, which has good heat insulation, abrasion resistance and high temperature resistance.
5. Coated brick
An anti-corrosion coating is sprayed on the surface of ordinary firebrick to improve its anti-alkali performance and service life.
6. Synthetic fiber reinforced brick
The toughness and anti-erosion ability of synthetic fiber reinforced brick can be improved by adding a certain amount of synthetic fiber reinforced brick.
7. Magnesia firebrick
Magnesite refractory brick refers to the refractory brick with magnesite as the material, magnesite as the main crystalline phase and MgO content of 80 ~ 85 percent. Its products are divided into metallurgical magnesia and magnesium products two categories. According to the chemical composition and use of different, there are Martin sand, general metallurgical magnesia, general magnesia brick, magnesia silicon brick, magnesia aluminum brick, magnesia calcium brick, magnesia carbon brick and other types. Magnesia refractory brick is the primary product of alkaline refractory brick. It has high refractories and good resistance to alkaline slag and iron slag. It is an important refractory brick. It is mainly used for open hearth furnace, oxygen converter, electric furnace and non-ferrous metal smelting.
It is important to note that different types of alkaline firebricks have different characteristics and scope of application, and appropriate products should be selected according to the specific use environment and needs. Alkaline refractory brick is a kind of special refractory material, mainly used in alkaline environment of high temperature equipment and kiln. What about alkaline firebricks? Here are some common alkaline firebricks.
