Problems solved by technology
[0003] For rubber hoses used in construction machinery and the petroleum industry, due to their large size and high pressure, the performance of the steel wires produced by the traditional production process cannot meet the requirements.
The rubber hose in this application generally requires a hose steel wire with a diameter > 0.80mm. The production of this steel wire has high requirements for production equipment and technology, and the production cannot be realized through the traditional production process.

[0047] The C content is 0.936%, the Mn content is 0.394%, the Si content is 0.212%, the P content is 0.016%, and the S content is 0.004%. The wire rod with a diameter of Ф 5.5mm is subjected to mechanical peeling, sand belt rust removal, and ultrasonic Water washing, boron coating and drying, etc., are drawn into a Ф1.60mm steel wire on a straight wire drawing machine, then degreasing and pickling in a degreasing tank, tandem water washing, pyrophosphate copper plating, zinc sulfate zinc plating, and then Intermediate-frequency heat diffusion to obtain Ф1.60mm copper-plated steel wire and steel wire for rubber hose reinforcement. The test performance comparison between the steel wire produced and the steel wire produced by the conventional process is as follows:

The invention discloses a steel wire for reinforcing a rubber hose and a production process of the steel wire, and relates to the technical field of production of steel wires for reinforcing rubber products. The production process of the steel wire comprises the following steps of carrying out surface pretreatment on a steel wire rod, carrying out coarse wire drawing and fine wire drawing on the steel wire rod which is subjected to surface pretreatment to obtain a drawn process steel wire; and carrying out copper plating and zinc plating on the drawn process steel wire, and then carrying out thermal diffusion to obtain the required copper-plated steel wire with a brass coating, namely the finished steel wire. According to the production process of the steel wire for reinforcing the rubberhose, the production of the large-specification rubber hose steel wire (the diameter is larger than or equal to 1.0 mm) can be achieved, meanwhile, various performance requirements of the steel wire can be met, intermediate heat treatment and water tank wire drawing procedures are omitted, the production cost is greatly reduced, meanwhile, the production efficiency is obviously improved, the quality and the comprehensive performance of the steel wire are remarkably improved, and the production process can adapt to the production of steel wires with various strengths.
Description
Technical field [0001] The invention relates to the technical field of steel wire production for reinforcing rubber products, in particular to a steel wire for reinforcing rubber hoses and a production process thereof. Background technique [0002] The performance requirements of rubber hoses are relatively high, and structural steel wires are commonly used as the skeleton material of hydraulic hoses and high-pressure hoses. The hose wire used for rubber hoses is a high-strength steel wire product coated with a uniform brass alloy on the surface. It is used in the form of braiding or winding to reinforce rubber hoses and is mainly used in hydraulic oil pipes. According to different purposes and use environments, high-pressure rubber hoses need to be able to withstand high temperature, high pressure, and high impact, and can be used in special occasions such as machinery, aviation, automobiles, oceans, and oil drilling. [0003] For the rubber hose used in construction machinery an...
