The electric furnace roof preforms are made of corundum, SiC, mullite and other materials with good wear resistance and high thermal shock stability as the main materials, and special composite micropowders are added as the binding agent, which are produced by special casting and baking processes. A material suitable for the top of electric furnaces. Its main characteristics are that it can withstand higher temperature radiation (2400°C) of arc light, has better wear resistance, higher thermal shock stability, more accurate appearance and size, and strong durability and peeling resistance. It is widely used in high-power electric furnaces at home and abroad with good results.
