We offer shaft and hearth-shaft furnaces for efficient melting of different copper qualities. Our shaft furnace allows highly efficient melting of copper cathodes, anode residues, and high-grade copper scrap. The nozzle-mix burner system with single burner control and the optimized furnace geometry contribute to this high efficiency. The feedstock is charged into the shaft with a skip hoist. Burners are mounted radially around the lower shaft section and provide the melting energy. The waste gases are guided upwards through the shaft to pre-heat solid scrap in the upper part. The liquid copper can be fed to the subsequent process step by means of a ladle or launder. Typical applications can be found in brass mills, rod mills and anode casting plants.
Additionally, the hearth shaft furnace is equipped with a hearth that allows holding and deslagging of the liquid copper. As a result, medium-quality scrap can also be used. The molten copper is transferred via launders to refining furnaces. The focus for a hearth-shaft furnace lies on continuous operation and a high daily capacity of up to 1,000 tons.
