The large single-weight titanium alloy round wire used for fasteners in Baoti Group Wire Rod Factory successfully passed the review

Welcoming the National Day, good news spread frequently. Recently, the project of "Development of Wire Materials for a Certain Model of Titanium Alloy Nuts" undertaken by the Wire Rod Factory passed the final acceptance, and the project of "Development and Application Research on TC4 and TC16 Titanium Alloy Large Single Heavy Disc Round Wire Materials for Aviation Fasteners" passed Process review. This marks a major breakthrough from development to application for Baoti fasteners using large single-weight titanium alloy round wire.

Fasteners are called "industrial rice". As an important basic part, titanium alloy fasteners are widely used in aerospace and other fields. The wires used to make titanium alloy fasteners need to have the characteristics of single weight, high size accuracy, good batch quality consistency, and self-contained lubricating coating on the surface. They have always relied on imports. In recent years, led by the main engine station and with the cooperation of fastener manufacturers, the wire rod factory has filled in a series of fastener wire production equipment, and has broken through many key technologies such as hot rolling of large single-weight titanium alloy wire blanks, size tolerance control of high-precision round wire materials, and surface coating of titanium alloy round wire materials for fasteners. It has successfully developed TC4, TC16 alloy and other large single-weight round wire materials with a single weight of more than 100 kilograms and meet technical requirements. The fastener upsetting verification was completed, and successfully passed the application evaluation, process review and final acceptance, laying good technical support for the subsequent industrialization promotion and application of such products.

Technological innovation is an important way to develop new productive forces. On the occasion of national celebration, the wire rod factory has broken through the "stuck neck" technology with product innovation, injected vitality into the development of the enterprise, and used practical actions to present gifts to the 75th anniversary of the founding of New China.
