Laser heat treatment process for a steel ring

Abstract

The invention relates to a laser heat treatment process for a steel ring, comprising the following steps: (1) pretreatment; (2) flaw detection to determine the area; (3) observing and measuring the repaired range of the steel ring surface, and carrying out the process in a control cabinet according to the measurement results Programming, written into the PLC control system; (4) Turn on the gas source to output carbon dioxide, nitrogen, and helium; (5) Turn on the laser, adjust the spot width to 9mm, and use WC‑12Co nanomaterials as cladding materials to lay thickness 0.5mm; (6) post-processing. The invention adopts the method of laser cladding, cladding WC-12Co nano-materials made according to a specific ratio on the surface of the steel ring to form a cladding layer, which improves the mechanical properties of the steel ring while realizing the repair of the steel ring , that is, the hardness, wear resistance, and toughness are all improved, realizing the remanufacturing of the steel ring, avoiding the waste of resources, and saving the maintenance and use costs of equipment.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a laser heat treatment process for steel rings. Background technique [0002] The steel ring is the part used to draw the copper wire on the wire drawing machine. When in use, the copper wire will be wound on a row of steel rings. During the wire drawing process, the steel ring will be worn to a certain extent, which will affect the drawing of the copper wire. effect and quality. Then the steel ring needs to be replaced in time to ensure the quality of production and processing. When the steel ring is disassembled, the whole machine needs to stop working, which affects the normal drawing and forming process of the copper wire, reduces the production efficiency of the factory, and replaces it with a new one after disassembly. The cost of the steel ring is relatively high, and it still needs to be replaced regularly, and the maintenance cost is high; the worn steel ring tha...

[0002] The steel ring is the part used to draw the copper wire on the wire drawing machine. When in use, the copper wire will be wound on a row of steel rings. During the wire drawing process, the steel ring will be worn to a certain extent, which will affect the drawing of the copper wire. effect and quality

Then the steel ring needs to be replaced in time to ensure the quality of production and processing. When the steel ring is disassembled, the whole machine needs to be stopped, which affects the normal drawing and forming process of the copper wire and reduces the production efficiency of the factory. After disassembly, replace it with a new one. The cost of the steel ring is relatively high, and it still needs to be replaced regularly, and the maintenance cost is high; the removed worn steel ring is not recycled, resulting in a serious waste of resources
