Abstract

The invention provides a continuous annealing apparatus and an annealing method of titanium and titanium alloy coiled wire material. The continuous annealing apparatus of titanium and titanium alloy coiled wire material comprises a heating mechanism and a continuous conveying mechanism, wherein, the heating mechanism comprises a box type heating furnace, and the continuous conveying mechanism comprises an internally fixed steel pipe of a wire material furnace, two sets of fixed pulleys and a continuous multiple winding wire rotating mechanism; the internally fixed steel pipe of the wire material furnace is equipped in the box type heating furnace, and the two sets of fixed pulleys are respectively arranged at two ends of the box type heating furnace, and are kept at the same horizontal line of the center line of the internally fixed steel pipe of the wire material furnace. The processed wire materials cross the heating furnace at a uniform speed, can be continuously and multiply wound, thereby realizing continuous and uniform annealing of wire materials with simple structure and good working reliability. The annealing method provided by the invention can be used for continuous and uniform constant temperature heating of single wire material, and during the moving process of wire material, the speed is constant, the heating is uniform, and the obtained wire material has uniform performance.

Description

technical field [0001] The invention belongs to the technical field of annealing of titanium and titanium alloys, and relates to a continuous annealing device for coiled wire materials of titanium and titanium alloys, and also relates to an annealing method of the annealing device. Background technique [0002] In recent years, due to the rapid development of the electronic product industry, small-sized titanium and titanium alloy wires (Φ1.5-Φ4.5mm) have been used as raw materials for fasteners such as screws due to their light weight, high specific strength, and good corrosion resistance. It is used for connecting and fixing motherboard accessories of electronic products such as mobile phones and tablet computers. This not only requires uniform performance of the entire batch of applied materials, but also uniform performance of the bearing surface when used as a small screw. The heat treatment and annealing process of small gauge wire has a decisive influence on its prop...
