Induction furnace coil putty is a refractory material specially used to protect induction furnace coils and medium frequency power supplies. This product is made of composite sand, special alum, corundum sand, powder organic powder as the matrix, and an appropriate amount of composite additives and ceramic binders are added to make it through premixing. Its design fully considers the refractory, insulation and operability, and can maintain excellent performance in high temperature environments. Once the molten metal penetrates into the furnace lining, the induction furnace coil putty can protect the coil from the dissolution of the molten metal in a short time. At the same time, the high strength and plasticity of the putty can support the induction coil and prevent it from deforming during use and removal of the furnace lining. It is particularly suitable for furnaces with ejection mechanisms, which plays a role in guiding and preventing the coil from being scratched. In addition, the putty has good insulation properties and can effectively prevent short circuits or discharges between coil turns, thereby avoiding the generation of excessive impact currents that cause damage to medium frequency power supply components such as thyristors. Overall, induction furnace coil putty is the preferred protective material for high-temperature equipment such as induction furnaces, and is widely used in power, metallurgy, nonferrous metals, petrochemicals and other industries.
