Ramming material for aluminum-magnesium spinel furnace for intermediate frequency furnace

Aluminum-magnesium spinel furnace lining material High-alumina refractory ramming material

This product is an fused corundum-based aluminum-magnesium spinel dry-vibration refractory material. It is specially designed to be used as the working lining of the coreless induction furnace for melting stainless steel, various high alloy steels and carbon steel. ALM-88A uses high-purity raw materials and a proprietary particle size distribution design to obtain a dense and uniform unshaped furnace lining. The material has good thermal shock stability and high temperature strength, and has a certain loose layer during normal use.
