Preparation process for stainless steel wire

Abstract

The invention discloses a preparation process for a stainless steel wire. The process comprises the following steps that firstly, an online coating drying device is used for coating a wire rod with a coating agent and drying the coating agent; secondly, the wire rod is guided into a thick straight wire-drawing machine to be continuously drawn 3-5 times; thirdly, surface heat treatment is carried out, the drawn wire rod is guided into a heat treatment furnace to be subjected to surface brightening treatment, and after heat treatment is completed, water cooling, water washing and drying are carried out; fourthly, the online coating drying device is used for coating the wire rod with the coating and drying the coating agent; fifthly, the wire is guided into a thin straight wire-drawing machine to be continuously drawn 3-5 times; sixthly, surface heat treatment is carried out, the drawn wire rod is guided into the heat treatment furnace to be subjected to surface brightening treatment, and after heat treatment is carried out, water cooling, water washing and drying are carried out; seventhly, the online coating drying device is used for coating the wire rod with the coating agent and drying the coating agent; eighthly, the wire rod is guided into a straight wire-drawing machine to be continuously drawn 12-13 times; and ninthly, wire taking is carried out. According to the preparation process for the stainless steel wire, the floor space of a production line is small, the quality of produced products is high, and the wire taking efficiency is high.

Description

technical field [0001] The invention relates to a preparation process of stainless steel wire, in particular to a preparation process of stainless steel spring steel wire. Background technique [0002] Stainless steel spring steel wire refers to the use of the elasticity of stainless steel in the quenched and tempered state, and then processed into stainless steel wire specially used to manufacture elastic elements such as springs; the elasticity of stainless steel depends on its ability to elastically deform, that is, within the specified range Inside, the ability to deform elastically allows it to withstand a certain load without permanent deformation after the load is removed. [0003] In the drawing process of stainless steel spring steel wire, it is necessary to use a coating agent to produce a layer of non-metallic coating on the surface of stainless steel. This layer of non-metallic coating can reduce the friction between metal and metal (that is, stainless steel wire...

Problems solved by technology

[0003] In the drawing process of stainless steel spring steel wire, it is necessary to use a coating agent to produce a layer of non-metallic coating on the surface of stainless steel. This layer of non-metallic coating can reduce the friction between metal and metal (that is, stainless steel wire and mold), It can prolong the service life of the mold, allow faster drawing speed and greater deformation, and can make the surface of the processed stainless steel wire smoother, thereby reducing the loss of the mold while improving production efficiency and drawing quality. Helps to reduce costs; the conventional film coating device is to pass stainless steel wire through the film tank and then dry it in an oven, so it needs to occupy a large area, which is not conducive to the expansion of enterprise production capacity;

[0004] At the same time, on-line bright heat treatment is also an important process in the process of stainless steel wire preparation. Its working process is: heat treatment of stainless steel wire through the furnace tube of the heating furnace, so that the surface of the workpiece is bright; It is found that a large amount of sediment is easily deposited on the inner wall of the furnace tube, which will cause the stainless steel wire to be scratched by the deposit deposited on the furnace tube wall after 3 to 4 months of use, resulting in a decline in product quality;

[0005] In addition, it needs to be taken up in the subsequent process of the preparation process. During the use of the conventional direct winding and take-up method, it is found that not only the take-up efficiency is poor, but also the take-up amount is small, which increases its transportation. cost
