Inductor coil grout is made of high alumina refractory materials and high temperature resistant adhesives. It is used for evenly coating the inner surface of the coil. It can contain a color pigment to distinguish the coil grout from the working lining. This grout helps the working lining of the induction furnace to expand and contract without any problems. This coating of coil grout also helps in preventing any damage to the coils if they come in contact with molten product.
