Problems solved by technology

In the annealing of rare and precious metals such as titanium foil or strip, it is generally considered that the temperature should not exceed 550°C, but in practice, it has been found that the annealing of titanium materials annealed at this temperature is not thorough enough, resulting in unstable product quality.

Abstract

The invention pertains to a titanium foil material or belt material annealing technology in the technical field of metal processing, which is carried out according to the steps as follows: (1) materials are put in a vacuum annealing furnace, with vacuumization degree up to above 10 to 7; (2) the materials are heated to 560 DEG C to 700 DEG C with heat insulation for 2 hours to 4 hours; and (3) the temperature is lowered to room temperature and the materials are taken out. The annealing technology of the invention has the advantages of thorough annealing, good effect on removing stress and stable product quality and overcomes the defect that presently, when titanium foil materials are annealed, the annealing under comparatively low temperature is not thorough enough, which results in that the product quality is not stable enough.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, especially the processing of rare and precious metals. Background technique [0002] Annealing is a commonly used method in metal material processing. In the annealing of rare and precious metals such as titanium foil or strip, it is generally considered that the temperature should not exceed 550°C, but it has been found in practice that the annealing of titanium materials annealed at this temperature is not thorough enough, resulting in unstable product quality. Contents of the invention [0003] The object of the present invention is to provide an annealing process for titanium foil or strip, so as to achieve thorough annealing and improve the product quality stability of titanium foil. [0004] Specifically, the annealing process of titanium foil or strip material is implemented according to the following steps: [0005] (1), put the material into the vacuum annealing fur...
