Method for manufacturing high-strength steel wire rope

Abstract

The invention discloses a method for manufacturing a high-strength steel wire rope. The method for manufacturing the high-strength steel wire rope includes the steps of purchase of steel wire rods, large drawing for making blanks, primary heat treatment, middle drawing, secondary heat treatment, electroplating, fine drawing, stranding 1x4-0.28, combining ropes 7x4-0.86, ultrasonic alcohol cleaning, gluing, rewinding, sub-packing and determining length, quality inspection, packing, storing and delivery, and the like. The steel wire rope manufactured by the process has the advantages of super high strength, high precision, good integration, good combination with polyurethane belts, no layering and the like, and the quality is high.

Description

Technical field [0001] The invention relates to a method for producing a high-strength steel wire rope, belonging to the technical field of steel wire rope manufacturing. Background technique [0002] A steel wire rope is a flexible rope twisted with multiple or multiple strands of thin steel wires. The steel wire rope is a rope twisted into a spiral with a certain number of strands twisted around the core of the rope. In material handling machinery, it is used for lifting, traction, tensioning and carrying. The steel wire rope has high strength, light weight, stable work, not easy to be broken suddenly, and reliable work. [0003] The previous steel wire rope has the following defects: [0004] The strength of the steel wire rope is not high, and the quality is poor; the steel wire rope needs to go through the electroplating tank back and forth during electrogalvanization, but the extra-long wire rope needs a longer electroplating tank during electroplating, and the workshop space...

AI Technical Summary

Problems solved by technology

[0004] The strength of the steel wire rope is not high and the quality is poor; when the steel wire rope is galvanized, it needs to pass through the electroplating tank back and forth, but the super long steel wire rope needs a longer electroplating tank during electroplating, and the space of the factory building is limited. In addition, the longer electroplating tank The current is high during electroplating, and high current galvanizing will lead to low precision of the wire rope

[0005] When the steel wire rope is ultrasonically cleaned, it is easy for the zinc layer to contact water, resulting in secondary oxidation pollution; when the glue tank in the gluing device overflows, it will easily fall out of the device, resulting in waste of glue; the elongation of conventional steel wire rope is not Low, which affects the service life of the steel wire rope for belt skeleton reinforcement
