In intermediate frequency induction furnace foundry, neutral lining material is an important protective measure for the furnace, it can avoid high temperature metal damage induction coil, more importantly, it can prevent molten metal in induction furnace leakage outside the furnace body, avoid high temperature metal damage.
The neutral lining material of induction furnace is a dry ramming material made of corundum sand, powder, aluminum and magnesium spinel powder and sintering agent.Its particle size distribution conforms to the theory of large bulk density, so the compact and uniform lining can be obtained by various knotting methods, which is mainly used for various alloy steel, carbon steel, stainless steel, etc. The material has good thermal shock stability, volume stability and high temperature strength.
