Manufactured with high-purity boron oxide, the anhydrous binder avoids introducing chemically bonded water into the lining. The premix is designed to reduce lining erosion and support lining life.
Standard premix specifications
Grade selection also depends on tapping temperature and the chemical composition of the liquid metal.
Foundry-grade specifications differ. Open the selected SIL-RAM specification sheet for its grain size, temperature rating and shelf life.
