Problems solved by technology

Traditional titanium alloy wire processing uses sponge titanium as the raw material, and it needs to go through more than ten processes such as piezo electrode, smelting, billet forging, forging, heating, rolling, pickling, heat treatment, wire drawing, etc. The following problems exist in this process : 1. There are many processing steps, quality control is difficult, and the processing cycle is long; 2. Each specification of wire needs to be invested in a mold, and the mold investment cost is high, and the mold life is short; 3. The total equipment of the existing technology high investment
However, this short-process preparation cannot be used for continuous wire production, and the obtained rod has a cast structure with poor performance, so it cannot be directly used for wire production.

Embodiment 1

[0127] Preparation of TC4 filament

[0128] S1, mixed feeding

[0129] According to the requirement of TC4 composition (V is 4.25%, A1 is 6.2%, O is 0.1%, Fe is 0.11%), calculate the weight of raw materials, among them, sponge titanium 10kg, aluminum vanadium alloy 0.811kg, aluminum beans 0.362kg, titanium dioxide 0.011kg , the iron ball is 0.005kg, and the weighing value of each billet bin is set respectively, and then the corresponding types of raw materials are added to the bins of different billet bins, the door of the feeding bin is opened, and the raw materials enter the weighing bin evenly from the bin bin, when the raw material entering the weighing bin reaches the set weight, a signal is given to close the automatic feeding bin door, and at the same time open the discharging bin door, the raw material enters the feeding channel through the discharging bin door and is then discharged under the action of gravity. It falls into the mixing bin, and automatically closes t...

Embodiment 2

[0144] Preparation of TA1 filaments

[0145] S1, mixed feeding

[0146] Set the weighing value of the billet bin to 10kg, then add titanium sponge into the bin of the billet bin, open the door of the feeding bin, and the raw material enters the weighing bin evenly from the bin, when the raw material entering the weighing bin reaches the required After the set weight, a signal is given to close the automatic feeding bin door, and at the same time open the discharging bin door, the raw material enters the feeding channel from the discharging bin door and then falls into the mixing bin under the action of gravity, and automatically closes after the feeding is completed discharge bin door;

[0147] In the mixing bin, the different raw materials are stirred evenly by pneumatic stirring, and the mixed raw materials are fed into the waiting bin in batches through the feeding controller, and the feeding screw sends the mixed raw materials in the waiting bin into the cooling bed in ba...

Abstract

The invention provides short-process continuous casting and continuous extrusion equipment for titanium or titanium alloy wires. The short-process continuous casting and continuous extrusion equipment comprises a mixing and feeding device, a melting and ingot casting device, a pulling device, a continuous rod making device, a continuous wire drawing device and a wire winding device. Different kinds of raw materials enter a cooling bed in the melting and ingot casting device after being fed and mixed, metal liquid is formed through heating and smelting of a plasma gun, the metal liquid overflows into a crystallizer for ingot casting forming, formed ingots enter the continuous rod making device after being pulled out through the pulling device, the structure form needed by wire drawing is obtained through the continuous rod making device, then the ingots enter the continuous wire drawing device for wire drawing to obtain formed wires, and the formed wires are wound into a reel through the wire winding device. The invention further provides a short-process preparation method for the titanium or titanium alloy wires. According to the short-process equipment for the titanium or titanium alloy wires, the machining procedure is shortened through continuous design, and the titanium alloy wires with more uniform components and better structure forms are obtained through the specific structural design of continuous casting and continuous extrusion.
