ALU-RAM 950 is designed as a dry-vibrated refractory for coreless induction furnaces used to melt zinc and zinc alloys, suitable for both mold-fusion and mold-extraction applications. ALU-RAM 650 utilizes high-quality high-alumina material as its primary raw material; through stringent control of particle-size distribution and binder selection, it effectively resists zinc-melt erosion, scouring, and penetration, while maintaining a well-structured loose backing layer to enhance the overall safety and performance of the furnace lining.
