Intermediate frequency induction  furnace coil protection (commonly known as red clay) usinghigh-auaity hig-grade refractory materialas material as base material,with mineralizer, surfactants,plasticizers,adhesives and materials,high normal temperature and high temperature strength,insulation characteristics and hardening speed as well.The use of induction coil coil clay can very good protection against erosion and damage of liquid metal current,and can effectively protect the medium frequency power supply.XYJ-101 is suitable for cast iron and small cast steel furnace；XYJ-102 is suitable for all electric furnace.
