Problems solved by technology

[0002] Fine-gauge carbon steel wire is widely used in various high-end transmission equipment, precision instruments, composite materials, etc., because such products have high requirements for technical indicators such as steel wire diameter, tensile strength, torsion, etc., so the fine-gauge carbon steel wire is increased Due to the difficulty of production and processing, the country can only produce fine-scale carbon steel wire above 0.10mm at present. For ultra-fine carbon steel wire less than 0.10mm, due to insufficient production and processing technology, it still cannot meet the conditions for mass production.

example 1

[0013] Example 1, to produce an ultra-fine carbon steel wire with a diameter of 0.04mm, the production process is: raw material wire rod → pickling, boronization → first dry drawing → heat treatment → second dry drawing → Heat treatment→electrogalvanizing→water tank drawing→finished product winding;

[0014] Among them, the raw material wire rod is KSC72A high-quality carbon steel with a diameter of 5.5mm;

[0015] The first dry drawing process: the diameter of the raw material wire rod is drawn into a steel wire of 1.5mm, the die drawing pass is 11 times, the total compression rate is 92.56%, and the partial compression rate of the first 10 times is 20-25% , the last partial compression rate is 12.11%, the working area angle of the drawing die is 9~13o, and the length of the sizing belt of the drawing die is (0.3~0.7)d 1 , d 1 It is the diameter of the outgoing steel wire; its process parameters are listed in Table 1 below:

Abstract

The invention relates to a production method of a superfine carbon steel wire. The production method is characterized in that the production process of the production method comprises the following steps of: coiling raw materials; pickling, and boronizing; carrying out dry type drawing for the first time; carrying out heat treatment; carrying out the dry type drawing for the second time; carrying out the heat treatment; electrogalvanizing; drawing a water tank; and winding a finished product. The production method disclosed by the invention can be used for producing the superfine carbon steel wire which has the advantages of high strength, low stress and good straight-through property in a batched way.

Description

technical field [0001] The invention relates to a production method of carbon steel wire, in particular to a production method of ultrafine carbon steel wire. Background technique [0002] Fine-gauge carbon steel wire is widely used in various high-end transmission equipment, precision instruments, composite materials, etc., because such products have high requirements for technical indicators such as steel wire diameter, tensile strength, torsion, etc., so the fine-gauge carbon steel wire is increased Due to the difficulty of production and processing, the country can only produce fine-gauge carbon steel wire above 0.10mm at present. For ultra-fine carbon steel wire less than 0.10mm, due to insufficient production and processing technology, it still cannot meet the conditions for mass production. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a production method of ultra-fine carbon steel wire with high...
