Customized Andalusite brick with high performance of thermal shock resistance for hot blast furnace
Brief introduction of Andalusite brick with high performance of thermal shock resistance
Andalusite brick with high performance of thermal shock resistances are a high-performance refractory material that is mainly used in industrial facilities that need to withstand high temperatures and extreme environments. The main components of Andalusite brick with high performance of thermal shock resistances include sillimanite (Kyanite), aluminum oxide (Al2O3) and silicon dioxide (SiO2). Sillimanite is an aluminum silicate mineral with the chemical formula Al2SiO5, which can be transformed into mullite at high temperatures, a very stable high-temperature phase that can enhance the structure and performance of bricks.
Advantages and characteristics of Andalusite brick with high performance of thermal shock resistance
High temperature stability: Andalusite brick with high performance of thermal shock resistances can withstand load softening temperatures as high as 1500℃ to 1650℃, which means they can maintain their shape and strength without deformation at extremely high temperatures.
Thermal shock stability: They have good thermal shock resistance and can withstand rapid changes in temperature without breaking easily.
Wear resistance: Andalusite brick with high performance of thermal shock resistances have high hardness and wear resistance, and can resist wear and mechanical impact.
Erosion resistance: They can resist chemical erosion, especially in corrosive environments common in industries such as steel, chemicals and building materials.
Organization structure: Andalusite brick with high performance of thermal shock resistances have a dense organization structure, which helps to improve their overall strength and durability.
Application of Andalusite brick with high performance of thermal shock resistances
Steel industry: used for linings and components of blast furnaces, open hearth furnaces, electric arc furnaces, continuous casting machines and other equipment.
Chemical industry: suitable for thermal insulation and refractory layers of high-temperature equipment such as sulfuric acid furnaces and synthetic ammonia furnaces.
Building materials industry: used for kilns for firing bricks, tiles, cement and other products.
Glass industry: used for linings of glass melting furnaces, especially in areas where high temperature stability and chemical stability are required.
Others: Andalusite brick with high performance of thermal shock resistances are also used to make refractory parts such as steel ladle and skateboards.

Thermal shock resistant Andalusite brick with high performance of thermal shock resistance for glass furnace
2.Quality Assurance Process of Sillimanite refractory brick
1)Going out the furnace→checkout→packing→qualified product→putting in storage→sale,
2)The process from raw to product are strictly tested by equipment.
1.Inspection and Control of incoming raw materials: according to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
2.Inspection and control of the process: during the production,every brick will be weighed twice strictly to reduce the error of weight .
3.Quality audit by quality management: inspection of product standardization of quality of each product by process control and experimentation, taking corrective measures timely whenever deviations are noted.
4.Before delivery, the inspectors will inspect the size,appearance, physical and chemical properties of brick again in factory.
Packing of Andalusite brick with high performance of thermal shock resistance
1.on wooden pallets with plastic cover: wooden pallet size :930*930 or 1000*1000mm,
