Monolithic Refractory
Product Introduction:
Table of Contents collapse
The corundum mullite pillar could form a dense structure through a high-temperature sintering process, which is widely used as the structural support and thermal insulation layer of high-temperature furnaces such as petrochemical cracking furnaces, ceramic tunnel kilns, and glass melting furnaces. It can withstand rapid cooling and heating conditions and reduce the heat storage loss of the furnace. In addition, the material also has acid and alkali corrosion resistance and oxidation resistance, which is suitable for extreme harsh environments.
Features:
- High temperature resistance, and long-term working temperature can reach 1600℃
- High mechanical strength
- Chemical corrosion resistance
- Service life in metallurgical kilns can reach 2-5 years (more than 3 times that of ordinary refractory materials)
Application:
Mainly used in metallurgy, ceramics, glass and chemical industries.
