FURNACE FOR LEAD-SLAG REDUCTION AND PROCESS FOR LEAD-SLAG REDUCTION

摘要

A furnace for lead-slag reduction includes a furnace body (1), bases (4) for supporting the furnace body (1), lances (6) for injecting pulverized coal and electrodes (7). The furnace body (1) includes a hearth, a feed inlet (11), a lead-liquid outlet (12), a slag tap (13), an emptying outlet (18), electrode insertion holes (17) set on top of the furnace body (1), a smoke outlet (14) and lance insertion holes (16) set on the bottom of the furnace body (1). The lances (6) can be inserted into the furnace through the lance insertion holes (16) to inject pulverized coal into the furnace. The electrodes (7) can be inserted into the furnace through the electrode insertion holes (17) to heat materials in the furnace. Furthermore, a process for lead-slag reduction is also described.
