Abstract

The invention discloses a novel high-grade miscellaneous copper refining furnace system which comprises a furnace body and an auxiliary system, wherein the furnace body is formed by butting and combining furnace tails of two fixed type refining reflection furnaces; two groups of combustion openings are symmetrically formed in the left end and the right end of the furnace body and are correspondingly provided with combustion systems and oxygen and gas supply systems; a high-grade copper outlet and a low-grade copper outlet are formed in one end of the furnace body and both adopt water cooling type structures; each copper outlet is correspondingly provided with a cooling water circulating system; a smoke discharging opening is formed in the middle of the furnace body; a material feeding working door is arranged on the furnace wall on one side of the furnace body; a reducing pipe is also arranged on each material feeding working door; each reducing pipe is externally connected with a reduced coal-based powder quantitative control device; three slag discharging openings are also formed in the furnace wall; sizing bricks are symmetrically mounted at the lower part of the furnace wall on two sides of the upper part of the furnace bottom; ventilating pipe structures are mounted on the sizing bricks. The novel high-grade miscellaneous copper refining furnace system is ingenious in structural design, integrates the advantages of three existing refining furnaces, and not only lowers the investment cost, but also is relatively energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical equipment field of miscellaneous copper fire refining, in particular to a novel high-grade miscellaneous copper refining furnace system. Background technique [0002] Generally speaking, miscellaneous copper with a grade higher than 90% is called high-grade miscellaneous copper, which can be cast into anode plates for electrolysis after a fire refining operation. At present, my country's high-grade miscellaneous copper fire refining has three process methods: refining reverberatory furnace, tilting refining furnace and NGL furnace, each of which has its own advantages and disadvantages. [0003] The main advantages of the refining reverberatory furnace: First, the heat exchange performance of the furnace is good, the process is mature, and it can handle various copper materials including large blister copper; second, the structure is simple and the cost is low; third, it is easy to operate, oxidation and reduction...
