Copper strip rolling production process flow

Abstract

The invention discloses a copper strip rolling production process flow. The copper strip rolling production process flow comprises the following twelve steps: 1) smelting; 2) hot rolling; 3) surface milling; 4) rough rolling; 5) annealing; 6) cleaning; 7) primary intermediate finish rolling; 8) secondary annealing and cleaning; 9) secondary intermediate finish rolling; 10) finish rolling; 11) finished product rolling; and 12) finished product straightening and slitting. According to the copper strip rolling production process flow, the mode of reducing the finished product rolling machining rate through low-temperature annealing is adopted, so that the hardness of a copper strip is guaranteed to reach the standard, and the plate shape of the copper strip is guaranteed; in the process, the steps are implemented strictly according to the requirements of a production scheme, so that the plate shape performance of the copper strip is improved; the quality of an edge of a 0.15SH product is obviously improved after the finished product rolling is finished, and the bending and straightening production does not need to be carried out after edge cutting is carried out in the finished product inspection, so that the labor and the cost are greatly saved; and the hardness performance is controlled within a minizone range of 185-190 through adjustment of the process and control of tolerance and the like in the process, so that the requirements of users on the performance of the copper strip can be met, and the process production and circulation are facilitated.

Description

technical field [0001] The invention relates to a copper strip technology, in particular to a copper strip rolling production process flow. Background technique [0002] Copper strip is a kind of metal component, mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, connectors, and mainly used as conductive, heat-conducting, and corrosion-resistant equipment. In the production process of 0.15SH series copper strips, Because the copper strip is relatively thin, and the hardness requirement is relatively high, the production and rolling passes are many, the plate shape is difficult to control during the rolling process, and the strip is easy to break. Due to the large rolling processing rate, the edge quality is not good, so it cannot be directly rolled. In order to ensure the quality of the product, it is necessary to cut the edge first before stretching and straightening, which greatly affects the production efficiency and causes...

[0002] Copper strip is a kind of metal component, mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, connectors, and mainly used as conductive, heat-conducting, and corrosion-resistant equipment. In the production process of 0.15SH series copper strips, Because the copper strip is relatively thin, and the hardness requirement is relatively high, the production and rolling passes are many, the plate shape is difficult to control during the rolling process, and the strip is easy to break. Due to the large rolling processing rate, the edge quality is not good, so it cannot be directly rolled. In order to ensure the quality of the product, it is necessary to cut the edge first before stretching and straightening, which greatly affects the production efficiency and causes a great waste of cost, and the copper produced by this method The belt can not meet the needs of customers with higher board requirements
