Embodiment 1

[0023] A processing method for a copper-titanium alloy pipe, comprising the following steps:

[0024] (1) Alloy smelting: Put the raw materials in a smelting furnace for smelting; the raw materials are: 25-35% copper, 5-8% zinc, 3-4% nickel, 2-3% tin, 0.2-0.5% aluminum, Silicon 0.2-0.4%, carbon 0.1-0.2%, iron 1-2%, and the rest are unavoidable impurities and titanium;

[0025] (2) Pouring: After the die-casting machine is closed, the alloy melt is filled into the cavity at a spray speed of 30-40m / s. After the alloy melt fills the cavity, it is molded into one body by die-casting machine. The filling pressure is 10-15MPa; to obtain a hollow tube blank;

[0026] (3) Extrusion: Extrude the hollow tube billet under high temperature conditions, and the extrusion speed is 3-5mm / s;

[0027] (4) Rolling: use a cold press to carry out multi-pass rolling on the tube blank, and perform degreasing treatment and annealing treatment after each rolling; the annealing treatment is specifica...

Abstract

The invention discloses a processing method for a copper-titanium alloy tubular product. The processing method comprises the following steps: (1) smelting an alloy: putting raw materials in a smeltingfurnace to be smelted; (2) pouring; (3) extruding; (4) rolling; and (5) surface treatment. According to the processing method based on titanium and assisted with copper disclosed by the invention, the prepared alloy tubular product is high in antiseptic property. The tensile strength of the alloy tubular product is good by means of extrusion and rolling.

Description

technical field [0001] The invention relates to a processing method for a copper-titanium alloy pipe, belonging to the technical field of titanium pipe processing. Background technique [0002] Titanium is a high-strength but low-quality metal that is fairly ductile; titanium has a relatively high melting point and is a good refractory metal. At the same time, titanium has excellent corrosion resistance. This important feature is not available in many metals. Nowadays, the demand for heat-resistant steel, weather-resistant steel and alloy steel in various industries is increasing significantly, and the performance requirements for various alloys are also increasing. Higher and higher, such as fire resistance, high strength, corrosion resistance, etc., these properties have a very important impact on the use of alloys. Alloys with several metals as the main components, such as nickel-copper alloy and aluminum alloy, have appeared. These alloys have their own excellent proper...
