Problems solved by technology

The disadvantages of this process are: first, it is only limited to titanium wire with a single weight of less than 10kg, and two people control one equipment, which is inefficient and the surface finish is not high. The need for high-speed and long-term continuous processing of processing equipment
Especially unmanned automatic production cannot be satisfied
The second is that the alkaline pickling process steps are harmful to the environment, not environmentally friendly, the performance is also unstable, and the surface finish is not high
Therefore, the production of large single-weight high-performance titanium and titanium alloy bright wire is still a problem, and the product is blank

Embodiment Construction

[0021] Embodiments of the present invention will be described in detail below.

[0022] In order to prepare large unit weight and high performance titanium and titanium alloy bright coil wire, the processing and preparation method of the present invention comprises the following steps:

[0023] Step 1: Raw material preparation, forging titanium and titanium alloy ingots with a single weight greater than 150kg into a rectangular billet with a side length of 115mm to 120mm with a forging press, and grinding residual defects, cracks, and grooves;

[0024] Step 2: Continuous hot rolling, heating the billet to 700-900°C, and rolling the billet to rod wire rod;

[0025] Step 3: Grinding, grinding after stripping the wire rod, grinding residual defects, cracks and grooves;

[0026] Step 4: The ground wire rod bar is continuously cold-drawn by multi-pass rolling die, that is, in each pass of online production, the bar is rolled at high speed between at least two pairs of series-con...

Abstract

The invention belongs to the field of metal machining, relates to titanium alloy wire machining, and in particular to a preparation method of a high-piece-weight and high-performance titanium and titanium alloy bright coiled wire. The preparation method comprises the steps of raw material preparation, hot continuous rolling, polishing, multi-gate rolling mold continuous cold drawing, online heat treatment, and inspection warehousing. Compared with the prior art, the preparation method has the following technical effects: the production of high-piece-weight disc round blanks is realized; the all-flow bright surface finishing of wire rods is realized; no environmental hazard is generated to satisfy the national environment protecting requirements; multiple processes are saved; the cost is prominently reduced; and the performance uniformity is stable.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal processing, and relates to the processing of titanium and titanium alloy wires, in particular to a method for processing and preparing large single-weight high-performance titanium and titanium alloy bright wires for fasteners. Background technique [0002] In the field of welding, as China has become the world's largest producer of ships, titanium and titanium alloys are more and more widely used in the shipbuilding field, and the requirements for titanium welding wire and electrodes are getting higher and higher, especially bright titanium welding wire 1. Welding rods will be widely used in place of original products due to their good weld seam quality. In the field of aerospace, the implementation of domestic large aircraft projects in recent years has brought new vitality to the domestic titanium wire market, and there will be greater growth in the application fields of welding wire a...
