• The advantages of silica-based refractory bricks
  

• Resistant to high temperatures

• The refractory temperature of silica bricks ranges from 1690℃ to 1730℃. They can maintain the stability and integrity of their structure at high temperatures. 

• Excellent thermal conductivity

• The refractory silicon bricks have excellent thermal conductivity, with a high softening temperature under load. Generally, it is above 1620℃, only 70-80℃ lower than its refractory degree. The thermal conductivity of the silicon bricks increases with the increase of working temperature, but no residual shrinkage occurs. 

• Outstanding corrosion resistance

• Silica bricks are an acid-resistant and fire-resistant material, possessing excellent resistance to acid slag erosion and high corrosion resistance to acids, alkalis, solutions and other chemical substances. 

• Dimensional stability

• The thermal expansion coefficient of silica-based refractory bricks is relatively low, so their dimensions change very little in high-temperature environments. 

• Customizability

• Silica-based refractory bricks can be customized according to various requirements, including size, shape and fire resistance level.

• The application of silica refractory bricks

• Metallurgical industry

• Silica refractory bricks are widely used in high-temperature smelting equipment in the metallurgical industry, such as blast furnaces, steel furnaces, iron smelting furnaces, electric furnaces and iron water treatment equipment. 

• Chemical Industry

• Siliceous refractory bricks can be used in high-temperature reaction furnaces, kilns, conversion furnaces, heating furnaces, heat exchangers and grate furnaces in the chemical industry. 

• Electric power industry

• Siliceous refractory bricks are widely used in high-temperature equipment in the electric power industry, such as combustion furnaces, boilers, chimneys and thermal power stations. 

• Glass and Ceramic Industry

• Refractory silica bricks are used in equipment such as glass furnaces, kilns and kilnware in the glass and ceramic industries. Due to their high heat resistance, they can withstand the melting process of high-temperature glass and ceramic materials, thereby ensuring product quality and production efficiency. 

• Steel Industry

• Refractory silica bricks are widely used in equipment such as steel ladles, iron gates, gates and iron water wells in the steel industry. They can withstand the impact and corrosion of high-temperature molten steel, protecting the durability and production efficiency of the equipment.
