Embodiment 1

[0021] A preparation method of 3mmZn-Cu-Ti alloy wire for spraying, comprising the following steps:

[0022] (1) Weigh pure copper block and titanium sponge according to the mass ratio of 4:3, use non-consumable vacuum electric arc furnace to smelt into Cu-Ti master alloy, and carry out electromagnetic stirring treatment on the alloy melt during the smelting process, smelting The number of times is not less than 3 times. After cooling, the alloy is broken into small pieces. In order to ensure uniform dissolution and increase the contact surface, the mass of each small alloy piece does not exceed 8g;

[0023] (2) The Zn-Cu-Ti alloy is smelted in a resistance furnace, that is, the pure zinc is melted first, and then the Cu-Ti intermediate alloy is respectively put into the zinc melt. As the most preferred process parameter, the temperature of the zinc melt is controlled at 650 ℃, if the temperature is too high, the zinc element will volatilize, which will affect the composition ...

Abstract

The invention relates to a preparation method of a 3 mm Zn-Cu-Ti alloy wire for spraying. The method comprises the following steps that 1. pure copper blocks and titanium sponge are weighed in proportion, and are smelted into a Cu-Ti intermediate alloy by adopting a non-consumable vacuum arc furnace, and after cooled, and the alloy is broken into small blocks; 2, a resistance furnace is adopted for smelting a Zn-Cu-Ti alloy, then Cu-Ti intermediate alloy is put into zinc melt, heat preservation is conducted till the Cu-Ti intermediate alloy is completely dissolved into the zinc melt, and thenthe Zn-Cu-Ti alloy melt is poured into a graphite mold; 3, a cylindrical cast ingot is put into the resistance furnace, is heated to 150 DEG C-180 DEG C, and taken out, and a layer of graphite emulsion lubricant is brushed over the cast ingot; and 4, the Zn-Cu-Ti cast ingot is put into an extrusion mold, the cast ingot and the extrusion mold are heated together, then isothermal extrusion is conducted, and one-step deformation is conducted to obtain the alloy wire. According to the preparation method, on one hand, the problem that a large amount of zinc volatilizes in a smelting process is solved, the zinc-copper-titanium alloy wire is prepared in one step, preparation procedures are reduced, the production cost is greatly reduced, and the productivity is improved.

Description

technical field [0001] The invention specifically relates to a preparation method of Zn-Cu-Ti alloy wire for spraying, which belongs to the field of material preparation. Background technique [0002] After nearly half a century of development, the application of zinc alloys in the world is becoming more and more extensive. Zinc alloy has the advantages of good fluidity, excellent mechanical properties, short production process, low energy consumption, etc., and my country has rich zinc resources accounting for 36% of the world's total, and its geological reserves rank first in the world. By the end of 2011, the proven The reserves are 42 million tons, and the development of new zinc alloy materials will have significant social and economic benefits, and will also help alleviate the shortage of domestic resources. Due to the abundant resources and low price of raw materials, the research and application of zinc alloys has attracted widespread attention in the field of non-fe...
