Electric connector copper alloy wire material produced through scrap copper and pyrogenic process thereof

Abstract

The invention discloses an electric connector copper alloy wire material produced through scrap copper and a pyrogenic process thereof. The pyrogenic process comprises the steps of weighing a certain amount of scrap copper, feeding the scrap copper into a blast furnace, and heating and melting till the scrap copper is softened, so as to obtain black copper; feeding the black copper obtained in the S1 into a conventer, and carrying out blowing to obtain secondary crude copper; pouring the secondary crude copper obtained in the S2 into a core induction reverberatory furnace for refining, and adding quartzite for high temperature heating refining, so as to obtain refined copper ingots; carrying out hot rolling process treatment on the refined copper ingots obtained in the S3, and after on-line annealing, carrying out cold rolling process treatment, so as to obtain a copper alloy wire material blank; pouring the copper alloy wire material blank obtained in the S4 into a pickling bath for pickling; after pickling, treating the pickled blank through a finishing straightening machine, and carrying out passivation treatment, so as to obtain a fine copper alloy wire material finished product; and inspecting and packaging the obtained fine copper alloy wire material finished product for storage. According to the electric connector copper alloy wire material produced through scrap copper and the pyrogenic process thereof, scrap copper is subjected to treatment of three procedures, and scrap copper of various complex components can be treated, and the the pyrogenic process is applied to a plurality of large-scale copper regeneration factories.

Description

technical field [0001] The invention relates to the field of copper alloy wires, in particular to a copper alloy wire produced from waste miscellaneous copper for electrical connectors and a pyrotechnic process thereof. Background technique [0002] There are three methods of pyrotechnics for producing copper alloy wires from scrap copper; [0003] The one-stage method is to put the sorted brass and red copper directly into the reverberatory furnace for fire smelting, and produce copper alloy wire rods in one step. It can handle scrap copper with less complex composition (copper content is required to exceed 90%). If dealing with miscellaneous copper with complex components, the process is difficult and the refining time is long. At the same time, this method is labor-intensive, the metal recovery rate is low (only 80-85%), and the slag contains high copper (25-30%); [0004] The two-stage method is carried out in two stages. In the first stage, waste miscellaneous copp...
