Abstract

The invention discloses a method for smelting a high-grade scrap copper by an anode furnace. The method for smelting the high-grade scrap copper by the anode furnace employs a rotary anode furnace facility for smelting. The rotary anode furnace comprises a furnace body, a feed port arranged in the middle portion at the front end of the furnace body, a combustor arranged on an end wall of the furnace body, ventilating bricks arranged at the lower end of the furnace body, and an oxide reduction pipe as well as a casting port arranged at the rear end of the furnace body; the furnace body is able to rotate in 360 degrees. The smelting method comprises the steps as follows: A, a feeding and melting stage; B, an oxidization slagging stage; C, a slag discharging stage; D, a reduction stage; and E, a casting stage. The invention solves the problem that, in the existing treatment technologies of the high-grade scrap copper, the raw materials are poor in adaptation, great in environmental contamination, low in automation degree, and the like.

Description

technical field [0001] The invention relates to the technical field of waste miscellaneous copper smelting, in particular to a method for smelting high-grade waste miscellaneous copper by utilizing a rotary anode furnace. Background technique [0002] The incoming materials of miscellaneous copper scrap are complex and diverse, and the chemical composition and physical specifications of various miscellaneous copper scraps are different. In practice, it is difficult to find a suitable smelting process for miscellaneous copper scrap. Even for high-grade scrap copper (materials with a copper content higher than 90%), it also contains about 10% impurities. The treatment of impurities in scrap copper or smelting flue gas has always been a difficult problem in this technical field. At present, the domestic and foreign equipment for processing high-grade miscellaneous copper mainly includes Osmelt furnace, reverberatory furnace, etc., and the "two-stage method" or "three-stage meth...
