Products Application
The main applications of alkali resistant bricks are:
1. Used for furnace lining: it can resist high alkalinity environment, so it is usually used for furnace lining, especially for hearth, furnace and other parts of steam furnace, steam power plant and other places.
2. Sintering furnace used in high alkalinity environment: due to its alkali resistance, especially in high alkalinity environment, it can be used as lining brick for sintering furnace, which can effectively resist the erosion of high alkalinity environment.
3. Alkaline flue gas purification equipment: It can be used for alkaline flue gas purification equipment, such as desulfurization and denitrification equipment, and organic waste gas purification equipment, which can effectively resist the erosion of alkaline gas.
4. Furnaces for high-temperature molten materials: with good alkali resistance, they can be used in furnaces for processing high-temperature molten materials, and can effectively resist the erosion of molten materials on the furnace lining.
