The shaft furnace is a high-efficiency, energy-saving aluminum melting equipment designed for continuous aluminum smelting processes (e.g., continuous casting, rolling, die casting). It features a vertical shaft structure with a large-cross-section flue at the rear and a high-speed burner at the flue bottom.
High thermal efficiency: Flue gas waste heat fully utilized.
Fast melting: Vertical preheating + flame impact.
Low burn-off: Flame away from charge, uniform heating.
Compact & easy operation: Top charging, no interruption to melting.
