Continuous casting process of nickel coated copper composite materials

Abstract

The invention provides a continuous casting process of nickel coated copper composite materials. The continuous casting process comprises the following steps of smelting copper and nickel and performing heat preservation on a copper and nickel solution in a heat preservation furnace; step 2, performing nickel pipe forming which comprises enabling the nickel solution to pass through a graphite crystallizer to form a nickel pipe, wherein a graphite core of the graphite crystallizer is in a hollow shape; step 3, hollowly pouring the copper solution into the formed nickel pipe through the graphite core in a rotating magnetic field environment simultaneously, maintaining the billet drawing speed to be 50 to 60 millimeters every minute and the cooling water temperature to be 20 to 50 DEG C in the process of horizontal continuous casting, enabling the current frequency of an alternating induction coil to be 18 to 30 Hz and the current intensity of the alternating induction coil to be 100 A when the rotating magnetic field is applied and obtaining nickel coated copper continuous casting billet; step 4, performing oxidation cleaning; step 5, performing surface treatment; step 6, performing storage. According to the continuous casting process of the nickel coated copper composite materials, the nickel coated copper wires are firm in combination, the production process is simple, the wastewater is not produced in the production process, and the environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to a production process method of a composite metal conductive material, in particular to a nickel-clad copper composite material continuous casting process. Background technique [0002] At present, domestic manufacturers of copper-nickel clad wire rods mainly use clad welding and drawing method for production, which has many processes, long process flow and low yield, so they can only make nickel-clad copper cables or nickel-clad copper clad wires with a thickness of less than 100 mm; The interfacial recombination mode is solid phase combination, the interface bonding strength is low, and the coating layer is uneven. The research based on copper-based composite materials is based on small-sized samples, but the application of copper alloys requires subsequent processing such as rolling and drawing, which greatly limits the application of copper-based composite materials.
