Material Introduction
Corundum mullite brick is a high-performance refractory material specifically designed for glass furnaces. It combines the high refractoriness of corundum with the excellent thermal shock resistance of mullite, making it an indispensable key material in the glass industry.
The refractoriness of corundum mullite bricks ranges from 1750°C to 1830°C, capable of withstanding the high-temperature environment and mechanical stress of glass melting furnaces. Its application in glass furnaces not only extends the service life of the furnace, but also reduces maintenance costs and improves production efficiency, making it an essential refractory material in the glass industry.
