Laser cleaning device and method for oxide skin on surface of hot-rolled high-carbon steel

Abstract

An embodiment of the invention relates to the technical field of laser processing, and discloses a laser cleaning device and method for the oxide skin on the surface of hot-rolled high-carbon steel. The laser cleaning device for the oxide skin on the surface of the hot-rolled high-carbon steel comprises an optical fiber laser and a cylindrical lens assembly. The cylindrical lens assembly is used for changing the two-dimensional distribution of laser beams emitted by the optical fiber laser so as to adjust the energy density of the laser beams to a cleaning threshold value. According to the laser cleaning device for the oxide skin on the surface of the hot-rolled high-carbon steel, the fiber laser is used for cleaning the surface and removing the oxide skin on the surface of the hot-rolledhigh-carbon steel containing the compact oxide skin, and non-contact machining is achieved. Compared with a traditional grinding method, laser machining has no direct impact on a workpiece and does not generate mechanical deformation. Compared with an acid pickling mode, no pollution is caused, the discharging and collecting processes of chemical stains are reduced, the influence of human factorson the machining quality is reduced, the machining quality is stable and reliable, and the appearance is attractive.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser cleaning device and method for oxide skin on the surface of hot-rolled high-carbon steel. Background technique [0002] There are various cleaning methods in the traditional cleaning industry, most of which use chemical reagents and mechanical methods for cleaning. Cleaning with chemical reagents is likely to cause environmental pollution, and mechanical cleaning is likely to cause wear on the surface of the object. [0003] Since the oxide scale on the surface of hot-rolled high-carbon steel is thick and dense, and the damage threshold of the oxide scale is relatively close to that of the base material itself, it is difficult to completely remove the oxide scale by using high-power homogenization and flat-top laser cleaning, and it is easy lead to secondary oxidation.
