Novel environment-friendly machining method for removing rare and precious metal oxide skin through laser burn washing method

Abstract

The invention discloses a novel environment-friendly machining method for removing rare and precious metal oxide skin through a laser burn washing method. The process technology is adopted for production, no adverse influence is produced on workpieces, and no loss is caused to material substrates almost. The working environment is clean, the production efficiency is relatively high, particularly in rare and precious metal pipe and special-shaped material surface treatment machining, since laser can automatically adapt to special-shaped surfaces such as a circular arc, the polishing and grinding workload can be greatly reduced, grinding apparatus grinding materials for polishing and grinding are saved, the loss of the rare and precious metal material substrates is effectively reduced, and the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of metal surface descaling processing, and in particular relates to a novel environment-friendly laser burn-washing processing method for removing rare metal oxide scales. Background technique [0002] Titanium (titanium alloy, zirconium, niobium, etc.) It is difficult to extract and process, and the production cost is high, so it is called rare and precious metal. The oxide scale generated during each thermal processing needs to be removed. The traditional production process is to remove the oxide scale by acid-base washing, sandblasting and other methods. There is a serious conflict between development requirements, and it is urgent to find a new environment-friendly production process to replace it. With the continuous development of laser technology, in recent years, its application in welding, cladding, spraying, cutting and other civilian fields has been greatly developed. Laser cleaning technology has also be...

[0002] Titanium (titanium alloy, zirconium, niobium, etc.) It is difficult to extract and process, and the production cost is high, so it is called rare and precious metal

The oxide scale generated during each thermal processing needs to be removed. The traditional production process is to remove the oxide scale by acid-base washing, sandblasting and other methods. The development requirements are seriously conflicting, and it is urgent to find a new environment-friendly production process to replace

With the continuous development of laser technology, in recent years, its application in welding, cladding, spraying, cutting and other civilian fields has been greatly developed. Laser cleaning technology has also been initially applied in the field of ferrous metal processing, but in rare In the field of laser cleaning and processing of precious metals, there have been many problems in the cleaning effect, and no progress has been made.
