Titanium wire is one of the metals that are difficult to stretch at room temperature. In the past, graphite resin coating was used, and it could only be stretched in one mold per pass. The surface coating must be removed by pickling before intermediate annealing, especially for wires with a diameter of less than 0.5 mm. , the production process is complicated, the cycle is long, the metal damage is large, and there are silver-white pits on the surface of the wire, and even the mold cannot be stretched due to the sticky mold of the tree. After more than two years of production practice, the titanium wire manufacturer has developed a simple lubricating coating (including lime, soap, garden powder, molybdenum disulfide) for titanium wire stretching, so as to achieve multiple Die stretching new technology. The process has the following characteristics:
New Technology of titanium welding filler wire Drawing
1. Realized multi-mode stretching (up to 7 modes), which greatly shortened the production cycle, increased labor productivity, and increased output by more than 5 times, thereby reducing costs and creating conditions for the civil use of titanium materials.
2. Simplify and shorten the process flow, reduce labor intensity, reduce the amount of industrial acid, and reduce metal loss by about 15%.
3. The surface quality of surgical medical titanium wire is improved (silver-white pitting is eliminated, and stretched surface wire with metallic luster is obtained), and the tolerance of wire diameter is reduced, thereby improving corrosion resistance.
4. In the past, it was difficult to prepare industrial pure titanium wire with a diameter of 0.06 mm. Now, after improvement, it can smoothly stretch industrial pure titanium wire with a diameter of 0.06 mm and titanium alloy wire with a diameter of 0.1 mm, expanding the diameter of the titanium wire. Specifications and scope of use provide corrosion-resistant mesh materials for printing and dyeing, chemical, light industry and other industries.
