Embodiment 1

[0012] The weight ratio is beryllium 2.0, phosphorus 0.1, copper balance, and impurities are less than or equal to 0.15. The beryllium copper ingot with the specification of Φ80mm×0.45mm×250mm is extruded on an 800-ton extrusion machine, and the heating temperature is 760-780° to form beryllium. Copper blank tube; annealed under the protection of H2 gas, the annealing temperature is 540-560 °, and then rapidly and strongly cooled to 15-35 °; after the tube is cooled and softened, it is rolled again, rolling speed and feeding amount: the speed is 95 times / min, the feeding rate is 2.5mm / min; after 4 stretches, the processing coefficient is controlled at 1.6;

Embodiment 2

[0014] Extrude beryllium-copper ingots with a diameter of 50mm, an inner hole of 30mm, a length of 210mm, a weight ratio of beryllium 0.2, phosphorus 0.2, copper balance, and impurities less than or equal to 0.15 through a 600-ton extrusion machine, and the heating temperature is 750-770 °, into beryllium copper blank tube; annealed under the protection of H2 gas, the annealing temperature is 500-520 °, and then rapidly and strongly cooled to 0-20 °; after the tube is cooled and softened, it is rolled again, rolling speed and feeding amount: The speed is 90 times / minute, and the feeding amount is 2mm / minute; after 3 stretches, the processing coefficient is controlled at 1.2;

Embodiment 3

[0016] Extrude beryllium-copper ingots with a diameter of 90mm, an inner hole of 50mm, a length of 300mm, a weight ratio of beryllium 2.5, phosphorus O, copper balance, and impurities less than or equal to 0.15 through an 800-ton extrusion machine, and the heating temperature is 780-800 °, into a beryllium copper rough tube; annealed under the protection of H2 gas, the annealing temperature is 580-600 °, and then rapidly and strongly cooled to 30-50 °; after the tube is cooled and softened, it is rolled again, the rolling speed and the feeding amount: The speed is 100 times / minute, and the feeding amount is 3mm / minute; after 10 stretches, the processing coefficient is controlled at 1.8.

Abstract

A technology for manufacturing the beryllium-copper pipe includes such steps as providing a beryllium-copper alloy ingot prepared from Be, P and Cu and with 50-90 mm for diameter, 30-50 mm for internal hole diameter and 210-300 mm for length, extruding at 750-800 deg.C by (600-800)-ton press, annealing in H2 at 500-600 deg.C, forced cooling to 0-50 deg.C, and rolling.

Description

technical field [0001] The invention relates to a method for manufacturing a copper tube, in particular to a method for manufacturing a beryllium copper tube. Background technique [0002] Beryllium is a heavy metal element with strong and light properties. [0003] Beryllium copper tube is a high-performance tube material for oil exploration, high-end communication equipment, and high-demand pressure instrument production. It is characterized by strong corrosion resistance, wear resistance, high strength and high elasticity. [0004] At present, there are beryllium copper strips, rods, and wires among the similar beryllium copper tube products in China, but there are no beryllium copper tubes. [0005] If the manufacturer needs it, one is to rely on imports; another alternative is to use beryllium copper rods to cut into short pieces, and then use machine tools to drill and cut; such utilization is inefficient, time-consuming and labor-intensive; if required If the pipe i...
