Ramming & Insulating Products
Silica ramming mass and boards
High-purity silica ramming mass for induction furnace linings and a range of insulating boards and papers for back-up and safety lining applications.
Built for consistent service.
Silica ramming mass is manufactured from selected quartzite deposits, crushed and sized to a defined particle distribution that gives dense, uniform ramming and predictable sintering. Insulating boards and papers complete the back-up and safety lining system.
