ALLOY MATERIAL ADDITION METHOD AND APPARATUS FOR SMELTING AND MELTING FURNACES

摘要

A method and apparatus for feeding alloy additive and burden materials to the burden in a vertical shaft furnace working volume generally by gravity-feeding the alloy additive to the furnace tuyere for entrainment in the blast media and transfer to the burden, which improves the recovery rate of the charged additive components in the molten metal and, allows utilization of undersized materials without secondary handling and treatment of the feed materials or utilization of pneumatic feed apparatus.
