Embodiment 1

[0032] (1) Melting ingot; (2) Milling; (3) Hot rolling; (4) Rough rolling; (5) Primary annealing; (6) Primary cleaning; (7) Intermediate rolling; (8) Secondary annealing; (9) Second cleaning; (10) Intermediate finishing rolling; (11) Three times annealing; (12) Three cleanings; (13) Finish rolling; (14) Four cleanings; (15) Leveling.

[0033] In step (1): After weighing the electrolytic copper plate and zinc ingot according to the composition standard of H65 brass, according to the melting points of the two materials, the electrolytic copper is first added to the power frequency cored induction heating furnace for melting, and then the zinc The ingot is added and melted. After stirring, slag removal, and composition inspection, when the temperature of the molten copper water is adjusted to 1060~1080°C, the molten copper water is poured into the water-cooled crystallizer, and then the casting machine is drawn to cast a thickness of For a 180mm ingot, dry borax is used to cover ...

Description

technical field [0001] The invention relates to the technical field of copper strip production technology, and more specifically, relates to a copper strip production technique for automobile contact parts. Background technique [0002] With the development of the national economy and the continuous improvement of people's living standards, automobiles have entered thousands of households as a mass commodity. A large number of connectors are required to realize electrical transmission and control on automobiles. Automotive connectors mainly include contacts, housings, The insulator and accessories are composed of four parts. The contact piece is the core part of the automotive connector to complete the electrical connection function. It is made of H65 brass strip through stamping, bending, electroplating and other processing methods. [0003] The quality of automobile contact parts directly affects the safety performance of automobiles, so the production requirements are str...
