Abstract

The invention discloses a production process of a copper rod, which comprises the following steps: 1) putting electrolytic copper raw materials into a closed mixed molten material furnace for smelting, and the smelting device is covered with charcoal and graphite flakes; 2) putting the closed mixed molten material The molten material in the furnace is transferred to the upward continuous casting molten material furnace; the molten material enters the continuous casting crystallizer through the siphon effect, and the crystallized upward copper rod in the continuous casting crystallizer is drawn from the continuous casting crystallizer through the pulling device. 3) the above lead copper rod is used as raw material, and the forming device of the continuous extrusion unit is used to extrude the copper wire billet; 4) the copper wire billet is rolled into a copper rod by the rolling unit; The back end of the pulling device is equipped with a twisting device, which utilizes the better ductility of the copper rod at high temperature, twists the copper rod with a higher temperature after drawing, and corrects the appearance of the drawn copper rod. It's more rounded.

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...
