Embodiment Construction

[0015] A production process of copper strip, which specifically includes the following steps: (1) Melting and continuous casting: mix copper material and zinc ingot according to the ratio of 3:1, and add a certain proportion of aluminum, iron, nickel, silicon, boron, manganese alloy at the same time After the material is put into the melting furnace and melted, the sample is quickly analyzed. After the composition is adjusted to pass, the copper liquid passes through the continuous casting machine and becomes a copper ingot; (2) Milling: the copper ingot is milled on the double-sided milling machine to remove the upper and lower surfaces of the billet. Improve the surface quality; (3) Hot rolling: heat the milled copper ingot to 800°C to 950°C in the heating furnace, and at the same time control the oxidation atmosphere and micro Reduce the atmosphere, and then use the hot rolling mill to roll the copper ingots with different deformation degrees for multiple passes, and roll th...

Abstract

The invention discloses a copper strip production process. The copper strip production process specifically comprises the following steps of (1) smelting and continuous casting; (2) surface milling; (3) hot rolling; (4) annealing; (5) acid pickling and cleaning; (6) fine rolling; and (7) shearing, packaging and warehousing. The copper strip production process has the beneficial conditions that after a raw material smelting alloy material is added, the weight of the raw material is controlled and the heating temperature and the heating environment are controlled during hot rolling, the oxidation burning loss of a copper material in a heating furnace can be reduced to a large extent, the yield of a finished product is controlled, a series of quality problems caused by heating oxidation of the copper material are reduced, annealing parameters are controlled, deformation resistance is lowered, the plasticity is restored, and the quality performance of the finished copper strip product produced by a method is good.

Description

technical field [0001] The invention relates to a copper strip production process. Background technique [0002] At present, copper strip production is mainly carried out by ingot hot rolling. However, with the continuous development of industrial technology, the quality and precision requirements of copper strips are getting higher and higher, and the traditional rolling method can no longer meet the requirements of high-quality copper strips. The annealing quality in the copper strip production process is poor, the parameter setting is not ideal, and the production operation is cumbersome, so that the produced copper strip cannot meet the production requirements. The main defects are as follows. Due to the rapid heat dissipation of the copper billet, the low degree of control of the hot rolling heating environment, and the inaccurate control of other steps, the defects of the copper strip are caused. Therefore, it is necessary to optimize the original production process,...
