It seems to be corundum casting precast blocks
Choose high-alumina or corundum refractory materials with different Al2O3 contents based on the operating temperature. High-purity corundum materials can be used at temperatures above 1800°C, but they have poor thermal shock resistance and are prone to cracking in the presence of temperature changes. It is recommended to use high-alumina castables with an aluminum content of 85% to 90%. Its operating temperature is above 1650°C.
Choose high-alumina or corundum refractory materials with different Al2O3 contents based on the operating temperature. For low temperatures, high-alumina castables with phosphate binders can be used.
