COPPER ANODE FURNACE AND A METHOD FOR OPERATING THE SAME

摘要

A copper anode furnace comprises a furnace drum (2), which can be pivoted about a horizontal axis and in which copper melt is refined into anode copper by means of fire refining. Said furnace drum (2) is provided with a spout (10) for pouring out the refined copper. A sliding closure (20) is arranged on the spout (10) of the furnace drum (2). Said sliding closure comprises at least one stationary, fireproof closing plate (21) and a fireproof sliding plate (22) which can be displaced relative to said closing plate. Through the displacement of the sliding plate (22), the outflow out the furnace drum (2) can be regulated or closed and therefore the outflow amount of the copper can be controlled. A drawing of slag into the casting, which reduces the anode quality, can be prevented using said sliding closure (20).
