Main raw materials of Andalusite Brick<\/h3>\n

Andalusite brick is made of andalusite as the main raw material, and is often added with powders such as sillimanite powder, mullite powder, calcined alumina powder, and high-alumina fine powder. Guangxi clay is also used as part of the binder.<\/p>\n

Production process of Andalusite Brick<\/h3>\n

First of all, the particle size, grade and impurities such as TiO\u2082 and R\u2082O in the raw materials must be strictly controlled. The raw materials are batched and mixed to make the various components evenly mixed, and then pressed into brick blanks through a molding process such as a pneumatic press, and then dried to remove moisture, and finally fired at high temperature, the firing temperature is usually around 1450\u2103-1500\u2103.<\/p>\n

Application of Andalusite Brick<\/h3>\n

Andalusite brick is mainly used in high-temperature industrial fields such as metallurgy and building materials. In the metallurgical industry, it is used for blast furnace hot blast furnaces, molten iron tanks, etc.; in the building materials industry, it can be used in kiln linings, combustion chambers and other parts. With its excellent performance, it can withstand high temperatures and chemical erosion, extending the service life of equipment.<\/p>\n
