Processing technology and processing equipment of high-smoothness corrosion-resistant high-strength stainless steel wire for ship

Abstract

The invention discloses a processing technology of a high-smoothness corrosion-resistant high-strength stainless steel wire for a ship. The processing technology comprises the following steps: step 1, cooling the stainless steel wire by air cooling, and feeding the stainless steel wire into a solid solution furnace for solid solution treatment; secondly, the stainless steel wire is straightened in the solid solution furnace body, and then secondary heating is conducted; thirdly, a wire outlet groove is cut in the outer side of the stainless steel wire through a laser cutting machine; fourthly, the stainless steel wire penetrates through a die with a die hole to shape the wire groove after being cut into the wire groove; 5, outputting and water-cooling the wire rod; step 6, conveying to a deep cooling machine for deep cooling; 7, the wire rod is tempered, and a final finished product is obtained.The invention further discloses equipment matched with the technology, the equipment is a solid solution furnace, and a wire rod straightening mechanism, a wire rod secondary heating channel, a laser cutting mechanism and a wire groove shaping die are sequentially arranged in a furnace body of the solid solution furnace. And the produced wire rod has the advantages of high smoothness, corrosion resistance and high strength.

Description

technical field [0001] The invention relates to a processing technology and processing equipment for high-gloss, corrosion-resistant, high-strength stainless steel wire used for ships. Background technique [0002] Stainless steel wires used in ships have high requirements for smoothness and corrosion resistance, and some stainless steel wires used to support and protect small and important cables such as optical fibers also require high strength requirements, because some ships Due to the special needs of the manufacturer, it is also necessary to manufacture complex wire slots around the outer circumference of small wires (outer diameter 1-3mm) for embedded cables to protect them, which brings difficulties to the manufacturing and processing of wires, mainly reflected in : [0003] If hot rolling is carried out at the outlet end of the spinning tube, the wire rod with grooves can be obtained at a relatively fast speed, but the wire groove precision of this wire rod is low,...

AI Technical Summary

Problems solved by technology

[0003] If hot rolling is carried out at the outlet end of the spinning tube, the wire rod with grooves can be obtained at a relatively fast speed, but the wire groove precision of this wire rod is low, and because the outer diameter of the wire rod is small, the amount of deformation generated during processing is large , can’t combine the requirements, and this method can’t process wires with complex slots; also because the structure inside the slots is more complicated, if cold drawing is used, the processing technology will become extremely complicated, and multiple cold drawing and Annealing will also cause great damage to the surface finish of the wire, and it needs to be solid solution treated again, which consumes a lot of energy. In addition, cold drawing is only suitable for processing shorter wires
