Problems solved by technology

[0002] At present, high-strength steel wires for prestressed steel strands are processed by forced die-drawing of reels to obtain steel wires with a strength exceeding 1900 MPa, but this processing method has many defects: ① The surface treatment quality is high, and acid must be carried out. Washing and phosphating treatment have huge environmental hazards; ② high-quality lubricants are required; ③ when drawing with a mold, a large amount of deformation heat is generated, resulting in poor plasticity of high-strength steel wire; ④ low production rate; ⑤ production cost high

Embodiment Construction

[0013] Embodiment of the present invention: the wire rod of SWRH82Bφ12.5mm is processed into a high-strength steel wire of φ5.05mm, combined with the attached figure 1 Be explained.

[0014] 1. Install and arrange the cemented carbide roll group

[0015] as attached figure 1 As shown in , two sets of cemented carbide rolls (1) are installed in a special stand, each set of rolls consists of three rolls, and the three rolls are evenly arranged in a star shape; the rolling surface of the rolls is an arc Shape, to ensure that the holes formed by the rolling surfaces of the three rolls are consistent with the required cross-sectional shape of the steel wire; arrange the two sets of rolls on the same straight line, so that the two holes formed by the two sets of rolls are aligned, and the two sets of rolls are aligned. The circumferential direction of the roll groups differs by 60 degrees, that is, if one set of rolls is arranged at 0, 120, and 240 degrees, the other set of rolls ...

Abstract

A high-strength steel wire processing method, the method uses rolling equipment and hard alloy rolls to roll the steel wire to obtain rolled steel wire products with required cross-sectional shape and size. The invention can change the sliding friction into rolling friction, and cancel the pickling and use of drawing powder, wire drawing die and other links in the production process, which is beneficial to environmental protection and occupational safety and health, and also improves production efficiency and reduces production cost , the toughness and plasticity of the processed high-strength steel wire are better.

Description

technical field [0001] The invention relates to a rolling rolling processing method of high-strength steel wire for steel strands, belonging to the field of wire product processing. Background technique [0002] At present, high-strength steel wires for prestressed steel strands are processed by forced die-drawing of reels to obtain steel wires with a strength exceeding 1900 MPa, but this processing method has many defects: ① The surface treatment quality is high, and acid must be carried out. Washing and phosphating treatment have huge environmental hazards; ② high-quality lubricants are required; ③ when drawing with a mold, a large amount of deformation heat is generated, resulting in poor plasticity of high-strength steel wire; ④ low production rate; ⑤ production cost high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a roll-rolling rolling processing method of high-strength steel wire in order to overcome...
