Silica bricks for coke ovens are mainly made of quartz material, and their silicon dioxide (SiO2) content is higher than 94.5%. Modern coke ovens are large-scale thermal equipment composed of thousands of refractory materials and tens of thousands of tons of refractory materials. Refractory silica bricks are the main material, occupying 60% to 70% of the basic parts of coke ovens such as regenerators, flues, combustion chambers, carbonization chambers and furnace tops. The service life of coke ovens is generally 20 to 30 years, and some can even reach 45 years. The quality of silica bricks is an important factor affecting the service life of coke ovens.
1. High purity: The silica brick has a silicon dioxide (SiO2) content higher than 94.5%, ensuring excellent high temperature resistance.
2. Long life: Made of high-quality raw materials and advanced production technology, the service life is up to 20-45 years.
3. Excellent thermal conductivity: higher thermal conductivity, improve thermal efficiency by 10%-20%.
4. High load softening temperature: able to withstand the live load of the furnace top trolley and maintain its shape unchanged.
5. Thermal shock stability: It has good thermal shock stability at high temperatures to prevent cracking and peeling.
1. Basic components of coke oven: such as regenerator, flue, combustion chamber, carbonization chamber and furnace top.
2. High-temperature industrial equipment: production links that require high temperature resistance and high wear resistance.
