The composition of the lining of the round steel induction heating furnace inductor

The lining form of the round steel induction heating furnace inductor is divided into silicon carbide lining and quartz sand knotted lining.

The silicon carbide lining of the round steel induction heating furnace inductor is sintered with silicon carbide material to form a furnace lining tube, which has the characteristics of high thermal conductivity, small thermal expansion coefficient and good thermal stability. The silicon carbide tube wrapped with aluminum silicate wool is directly put into It can be used in the inductor coil, the furnace lining is easy to replace, and the disadvantage is that it is easily broken, and the service life is shorter than that of the knotted furnace lining.

The knotted lining of the round steel induction heating furnace inductor is made of quartz sand, high-quality refractory powder, high-strength temperature-resistant chemical binder and additives, and has the characteristics of good temperature resistance and high bonding strength. The particle size is generally less than 1mm, and it needs to be used after adding water. Generally, a mold is placed inside the coil, and the furnace lining material is poured into the coil by vibration, and after it is dried and solidified, oven sintering is required during the service period to enhance the service life of the furnace lining.
