[0002] Cold rolling is an important processing method in metal processing. It is mainly used to process metal materials at room temperature or slightly heated through a rolling mill to change their shape, size and physical properties. It is widely used in the production of metals such as steel, aluminum, and copper, especially in the manufacture of thin plates, strips, and wires.

[0003] It is extremely difficult to produce alloy wires with a very different width-to-thickness ratio. The traditional method is to use thin strip trimming technology, which results in uneven edges for the products. If the trimming tool is improper or the operation is slightly deviated, the product will have burrs, curling, etc., resulting in great waste. Summary of the invention

[0010] In a preferred embodiment of the present invention, as the number of rolling times increases, the size difference between two adjacent rolling times gradually decreases.

[0011] In a preferred embodiment of the present invention, the cold drawing liquid during cold drawing in step 1) is prepared with vegetable oil, water, emulsifier, antioxidant, anti-wear agent and preservative.

[0016] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0017] An ultra-flat manufacturing process for producing alloy wires with a large width-to-thickness ratio difference includes using multiple tempering and reduction technologies to roll round billets into alloy wires with a large width-to-thickness ratio difference, which can ensure that the edges of the products are smooth and thorn-free. Resistance is measured at irregular intervals during the rolling process to ensure resistance stability, while reducing waste and ensuring quality.

[0018] The specific steps include:

[0019] 1) Cold drawing treatment: The round billet is cold drawn after pipe annealing. Pipe annealing is a heat treatment process mainly used in the processing of metal pipes to improve their mechanical properties and extend their service life. The annealing process heats the metal to a specific temperature and then slowly cools it under controlled conditions to eliminate internal stress, improve plasticity and toughness, and reduce hardness.

[0020] 2) Billet heating: the round billet after cold drawing in step 1) is placed in a rolling mill for multiple rolling. As the number of rolling times increases, the size difference between two adjacent rolling times gradually decreases, making the surface smoother.

[0021] The number of the multiple rolling passes is 12, and the billet is subjected to hydrogen protection pipeline softening annealing treatment, hydrogen protection softening treatment and hydrogen protection bright annealing treatment after the 5th, 9th and 12th rolling passes respectively. Since the billet cools and hardens after multiple rolling passes, it is necessary to soften the billet through the hydrogen protection pipeline softening annealing treatment, the hydrogen protection softening treatment and the hydrogen protection bright annealing treatment before the next rolling step.

[0022] The hydrogen protection pipeline softening annealing treatment is used to eliminate the internal stress generated in the material during the manufacturing process and improve the plasticity and toughness of the metal.

[0023] The hydrogen-protected softened area is used to enhance the machinability of the material, reduce its hardness, and facilitate subsequent processing.

[0024] The hydrogen protection bright annealing treatment not only softens the material, but also improves its surface quality to obtain a bright surface state.

[0025] In the step 1), the cold drawing liquid is prepared by using vegetable oil, water, emulsifier, antioxidant, anti-wear agent and preservative during cold drawing, and the preparation steps are as follows:

[0026] Preparation of emulsion: Mix 20% to 30% water and 3% to 5% emulsifier first, and stir with a stirrer or emulsifier until the emulsifier is completely dissolved and a stable emulsion is formed.

[0027] Vegetable oil addition: Slowly add 40% to 60% vegetable oil into the emulsion and continue stirring until a uniform mixture is formed.

[0028] Add other ingredients: Add 0.5% to 1% antioxidant, 1% to 3% anti-wear agent, 0.5% to 1% preservative, etc. to the mixed solution, and continue stirring to ensure that these additives are completely dissolved to form a cold drawing liquid.

[0029] Filtration and storage: Filter the cold drawn liquid through a strainer to remove impurities and store in a sealed container.

[0030] The types of vegetable oils include rapeseed oil, soybean oil and sunflower oil. Vegetable oil serves as the basic component of cold drawing fluid and provides lubrication.

[0031] Water is used to increase the cooling effect and is the main ingredient in forming the emulsion.

[0032] The types of emulsifiers include polyvinyl alcohol, polyoxyethylene and sodium dodecylbenzene sulfonate. The function of the emulsifier is to help the vegetable oil and water mix to form a stable emulsion.

[0033] Types of antioxidants include butylated hydroxyanisole and tert-butylhydroquinone. Antioxidants can extend the service life of cold drawing fluid and prevent it from deteriorating under high temperature or oxygen.

[0034] Types of anti-wear agents include phosphates, sulfides and zinc diene disulfide. Anti-wear agents help reduce friction and wear and improve the efficiency of cold drawing.

[0035] Preservatives are used to prevent the growth of microorganisms in the cold drawing fluid during use.

[0036] Example 1

[0037] The 4mm round billet is rolled into an alloy wire with a width of 10mm and a thickness of 0.1mm.

[0038] 1) Cold drawing treatment: After the 4mm round billet is annealed in the pipe, it is cold drawn to a 3.2mm round billet.

[0039] 2) Billet heating: The 3.2 mm round billet after cold drawing in step 1) is placed in a 230-roll medium-sized rolling mill for multi-pass rolling. As the number of rolling passes increases, the size difference between two adjacent rolling passes gradually decreases, which are 5.4 mm, 6.8 mm, 7.8 mm, 8.5 mm, 8.9 mm, 9.3 mm, 9.5 mm, 9.55 mm, 9.8 mm, 9.9 mm, 9.95 mm and 10 mm, respectively.

[0040] After rolling at 8.9 mm, 9.8 mm and 10 mm, the billets were subjected to hydrogen protection pipeline softening annealing, hydrogen protection softening and hydrogen protection bright annealing respectively.

[0041] Compared with the prior art, the present invention provides an ultra-flat manufacturing process for producing alloy wires with a large width-to-thickness ratio difference. The process adopts multiple tempering and reduction technologies to ensure that the edges of the products are smooth and thorn-free. The resistance is measured at irregular intervals during the rolling process to ensure the stability of the resistance, while reducing waste and ensuring quality.
