Abstract

The invention discloses a production process for a copper bar. The production process comprises the following steps of 1) putting an electrolytic copper raw material in a closed mixed melting furnaceto be smelted, wherein charcoal and graphite flakes cover the inner side of the smelting device; 2) transferring the melted material in the closed mixed melting furnace to an up-drawing continuous casting melting furnace; feeding the melted material into a continuous casting crystallizer by means of syphonage, and extracting a crystallized up-drawing copper bar in the continuous casting crystallizer from the top of the continuous casting crystallizer through a drawing device; 3) by taking the up-drawing copper bar as a raw material, extruding the up-drawing copper bar to prepare a copper wireblank by using a forming device of a continuous extruding unit; and 4) rolling the copper wire blank to a copper bar by using a rolling unit. A rubbing and twisting device is arranged at the back endof the drawing device to rub and twist the drawn copper bar which is relatively high in temperature by means of relatively good ductility of the copper bar at a high temperature. The outer surface ofthe drawn copper bar is corrected, so that the copper bar is more mellow and full.

Description

technical field [0001] The invention relates to the field of copper rod production, in particular to a production process for copper rods. Background technique [0002] Wind power is the cleanest and safest power generation technology at present. At present, the development speed of wind power in the world is faster than that of other new energy sources. In the future, wind power is likely to become one of the main sources of global electricity. According to the forecast of China Wind Energy Association, the total installed capacity of wind power in China will reach 8 billion watts in 2020, 18 billion watts in 2030, and 50 billion watts in 2050. The Chinese government will strongly support the construction of smart grids to solve the problem of wind power transmission. In the future, wind power will become one of the main sources of electricity in our country. [0003] Generator sets, transformers, traction motors, contact wires, etc. used in the above industries all need a...
