Corrosion-resistant zinc-aluminum alloy steel wire heat treatment equipment and process for ocean engineering

Abstract

This invention relates to the field of metal heat treatment technology, specifically disclosing a heat treatment equipment and process for corrosion-resistant zinc-aluminum alloy steel wire used in marine engineering. The equipment includes a housing and multiple sets of spliced ​​portal frames inside, dividing the heat treatment chamber into several independent heating chambers with temperatures increasing from bottom to top. The portal frames are equipped with guide cylinders with external spiral guide grooves. First and second mating balls are respectively provided on the bottom wall of the external spiral guide grooves and radial limiting strips, through which the steel wire is wound. A stress-relieving assembly is provided in the winding direction, comprising upper and lower rollers with the same helix angle and opposite rotation directions, and a freely rotatable connecting pipe, used to offset and release the accumulated torsional stress of the steel wire. This invention achieves preheating, heating, and homogenization through gradient temperature zones, improving the uniformity of the microstructure. The stress-relieving structure prevents the steel wire from twisting and deforming. The modular portal frames facilitate assembly and maintenance, significantly improving heat treatment quality and production efficiency.
