Phi 0.03m special titanium filament processing process

Abstract

The invention discloses a 0.03m special titanium filament processing process, belonging to the field of metal fine machining. The processing process mainly comprises wire drawing, heat treatment and oxidizing scale treatment; a method for fixing a framework and two ends of a wiredrawing shaft is adopted in two times of wire drawing; by adopting a special lubricating agent, the friction force of the surface of a titanium wire and a calibrating strap part of a wiredrawing film can be reduced; different heat treatment temperatures or annealing points are adopted in two heat treatment processes and the uniform line velocity can be kept; the problems of low tensile strength and poor elongation percentage can be solved; and by adopting a single-line multi-head continuous cleaning method in the treatment process of oxidation scale, the resistance for the titanium wire to pass through a wire release rack, a rinsing tank and leaching pond and to be subjected to drying, taking up and other links can be reduced. The invention has the advantages of simple process and high processing efficiency; the processed titanium wire has high tensile strength and favorable elongation percentage; and the processing of a 0.03mm titanium wire can be realized.

Description

Technical field: The invention relates to a metal ultrafine processing, in particular to a special titanium micro-filament processing technology. Background technique: Titanium is a rare metal with excellent characteristics such as low density, high temperature resistance, low temperature resistance, corrosion resistance, and good stability. Titanium alloys have high strength and high strength. The density is half that of steel and the strength is almost the same as steel. At -253 High strength can be maintained in a wide temperature range from ℃ to 500℃; these advantages are necessary for space metals. Titanium alloys are good materials for making rocket engine shells, artificial satellites, and spacecraft. Titanium has " Titanium is also known as a pure metal, and when substances come into contact with it, no chemical reaction will occur, because titanium has high corrosion resistance and high stability, so that it will not affect other materials after long-term contact wi...
