1. Silicon bricks refer to the refractory tiles containing SIO293%or more, which are the main varieties of acid refractory bricks. It is mainly used for building coke ovens, as well as the vaults and other load -bearing parts of various glass, ceramics, carbon crickets, and fire -resistant bricks. Under 600 ° C and use the temperature of the hot workers with large temperature fluctuations.
2. Fireclay bricks, clay bricks are mainly composed of Mullite (25%to 50%), glass phase (25%to 60%), and square quartz and quartz (up to 30%). Usually it is used as raw materials for hard clay, and the mature material is burn in advance, and then it is equipped with soft clay. It is formed in a semi -dry or plastic method. You can also add a small amount of water glass, cement and other binding agents to make non -firing products and irregular materials. It is a common refractory brick in blast furnace, hot air furnace, heating furnace, power boiler, lime kiln, rotary kiln, ceramic and refractory brick firing kiln.
3. High aluminum fire -resistant brick, high aluminum fire -resistant brick minerals are composed of rigid jade, Mo Lai Shi and glass phase. Its content depends on the type and quantity of the Al2O3/ SiO2 ratio and impurities. It can be divided according to the level of fire tiles according to the Al2O3 content. The raw materials are natural ore with high aluminum alum and silicon -threaded stone, as well as adding electric melting rigid jade, sintering aluminum, synthetic Mo Lai stone, and clinker with aluminum alumina and clay. It is produced by sintering method. However, the product also has melting bricks, molten bricks, non -burning bricks and irregular refractory bricks. High aluminum refractory bricks are widely used in the steel industry, non -ferrous metal industry and other industries.
4. Corundum bricks, corundum bricks refer to a kind of refractory brick with AL2O3 content of not less than 90%, with corundum as the main thing, which can be divided into sintering type jade bricks and electrical tiles.
