Problems solved by technology

[0004] The traditional production process has the following disadvantages: ① Vacuum smelting and casting consumes a lot of energy, low efficiency, and high production costs; The length of Zr alloy rods is limited, so it is impossible to produce ultra-long Cu-Cr-Zr alloy wire rods; ③The production process is more, the production cycle is long, and the yield is reduced due to more production processes; ④Cu-Ti alloy has a higher strength , the extrusion of the prepared ingot is more difficult, and the cold drawing of the extruded bar is more difficult, and multiple intermediate annealings are required

Embodiment 1

[0029] Take industrial electrolytic copper, copper-chromium master alloy, zirconium wire and other alloy raw materials respectively according to Table 1. The specific preparation process is as follows: ① Smelting: install the horizontal continuous casting crystallizer 11 before melting the alloy, so that the horizontal continuous casting crystallizer 11 is in the It is in a closed state during the smelting process. After the installation of the horizontal continuous casting crystallizer 11 is completed, the proportionally proportioned electrolytic copper and other alloys are loaded into the induction furnace, and put into the furnace 7 from the feeding port 5 so that they are contained in the inner lining 8 of the crucible. , you can also open the furnace cover 3 and directly add raw materials; cover the cover and the observation window 4, open the protective gas valve, and feed argon gas from the upper air inlet 2 until the air is discharged from the upper feeding port 5 and th...

Embodiment 2

[0034] According to Table 2, the alloy raw materials such as industrial electrolytic copper and sponge titanium were respectively taken, and the Cu-Ti alloy wire rod was prepared with the same process steps as in Example 1. The melting loss rate of each element is shown in Table 2.

[0036] raw material

[0037] In summary, the equipment of the present invention has successfully shortened the traditional vacuum furnace production process: vacuum smelting—vacuum casting—peeling—extrusion—heat treatment—drawing—finished product to: alloy smelting—continuous drawing casting ——drawing——the finished wire rod. It is widely used in the production and preparation of easy-to-oxidize alloys such as Cu-Cr-Zr and Cu-Ti, and alloy wire rods such as Cu-Ti that are difficult to deform, and the length is not limited. Vacuum furnace melting is not used, which enables continuous production, significantly improves the yield of alloy materials, realizes energy saving a...

Abstract

The invention relates to equipment for preparing an alloyed wire rod which is easy to be oxidated and difficult to be distorted. A smelting furnace adopts a non-vacuum induction smelting furnace protected by the atmosphere, holes are arranged on the side of the smelting furnace body, horizontal continuous casting crystallizers with different cross sections and specifications are installed at the side hole positions, the sprues of the horizontal continuous casting crystallizers are communicated with the smelting furnace body, draughting mechanisms are arranged at the outlet openings of the horizontal continuous casting crystallizers, and curling mechanisms are connected with the draughting mechanisms end to end. The horizontal continuous casting alloyed wire rod is realized through installing the horizontal continuous casting crystallizers with different cross sections and specifications at the side hole positions, for the sizes of the horizontal continuous casting crystallizers, different specifications and different cross sections are determined according to product demand, the draughting mechanisms realize that the wire rod advances at the specified casting draughting speed, the curling mechanisms realize to collect the alloyed wire rod, so that the length of the wire rod can be expanded, the invention is widely suitable for production equipment of the wire rod of easily oxidable alloys of Cu-Cr-Zr, Cu-Ti, etc., and difficultly distorted alloys of Cu-Ti, etc.

Description

technical field [0001] The invention relates to a device for preparing easily oxidizable and difficult-to-deform alloy wire rods, in particular to a short-process preparation device capable of obtaining ultra-long Cu-Cr-Zr and Cu-Ti alloy wire rods, belonging to the technical field of non-ferrous metal processing. Background technique [0002] Due to the high strength and electrical conductivity of Cu-Cr-Zr alloy, its rod-shaped wire products are widely used in electronics, electric power, automobile, light industry, transportation and other industries, especially the ultra-long Cu-Cr-Zr alloy rod wire The realization of production makes it more market application prospect. However, since Zr is easily oxidized and burned in the atmosphere, it is difficult to produce Cu-Cr-Zr alloy wire rods without vacuum. Cu-Ti alloy is also very easy to oxidize and burn due to Ti in the air, and Cu-Ti alloy has high strength due to the addition of Ti (especially the alloy strength is high...
