Electric Refining Furnace Bottom Ramming Mass

Ramming mass for ferroalloy refining furnaces and submerged arc furnaces where anti-penetration behavior, reliable sintered-layer formation, and practical field construction all matter directly.

Neutral induction working-lining route for stainless, alloy-steel, and special-alloy melting where broad metallurgical fit, stable lining formation, and short sintering time matter together.

Basic induction working-lining route for small-tonnage furnaces where stronger basic-service matching, short sintering time, and steadier high-temperature performance matter most.

Acid ramming mass is based on quality quartz sand and is used where silica-compatible induction routes are preferred. Thehighlights easy use, good volume stability, no blasting or peeling during service, and stronger high-temperature behavior than ordinary acid masses.
