Method and device for adding alloying elements

Abstract

The invention relates to an alloy element adding method and device. The device comprises a device body, a feeding mechanism and a crystallizing pond, wherein the feeding mechanism comprises a feeding funnel, a feeding push rod, a spring, an argon gas introducing pipe and a graphite pipe; the lower end of the graphite pipe is inserted into the crystallizing pond. The method for adding alloy by the device comprises the following steps: (1) loading materials; (2) conveying the materials by argon gas; (3) getting the materials; (4) pushing the materials; (5) adding. The adding device and method are used for quantitatively and effectively adding alloy elements in a smelting process for preparing microalloy copper materials, and the alloy elements are directly added into liquid and uniformly and stably diffused, so that the labor intensity is reduced, the air admission is avoided, the energy consumption is reduced, and the alloy elements are relatively uniform and stable; the prepared copper materials belong to high-grade products and are widely applied to the industries of electricity, electronics, electrics, instruments, aviation, traffic, buildings, communication, military affairs and the like.

Description

technical field [0001] The invention relates to a method and a device for adding alloy elements, and belongs to the technical field of microalloy copper melting and casting. Background technique [0002] The existing micro-alloy copper melting and casting process: Melting copper liquid in a cored power frequency induction furnace—heating in a holding furnace—artificially taking alloy elements—weighing and putting in alloys—electromagnetic vibration (for uniform alloy composition)—introduction and casting to make copper alloys. [0003] Chinese invention patent 03116839.6 discloses a method for adding alloys to molten metal. The molten metal is poured from the liquid metal storage container into the crystallizer through the submerged discharge pipe. Alloy materials are added. The feeding device includes an immersion discharge pipe, a gas sealing device, at least one conduit, and an induction heater; wherein, the two ends of the immersion discharge pipe are respectively conne...

AI Technical Summary

Problems solved by technology

[0006] 2. Manual weighing is required for each delivery, which is cumbersome and inefficient;

[0007] 3. During the feeding process, the insulation furnace cover needs to be opened frequently, which increases the entry of air, which will increase the oxygen content of the copper liquid and affect the product performance.
