Embodiment 1
[0020] A processing technology of copper-titanium composite pipe, comprising the following steps:
[0021] (1) The lubricant is sprayed on the surface of the copper rod, and at the same time, the copper rod is placed in the titanium tube to obtain a titanium copper rod; the lubricant includes the following components in parts by weight: 20 parts of molybdenum disulfide, 10 parts of graphite , 25 parts of nano silicon dioxide and 2 parts of glass fiber.
[0022] (2) Put the titanium-copper rod in step (1) into the electric furnace to heat, keep the temperature of the electric furnace at 800-900°C, and draw it with a suitable mold;
[0023] (3) The drawn titanium-copper rod is rolled by a cold press for multiple passes, and degreasing treatment and annealing treatment are carried out after each rolling; the annealing treatment is specifically: under vacuum conditions, the tube blank is quickly Heat up to 280-320°C, keep warm for 10-15min; slowly heat up to 850-950°C, keep warm ...
