Laser strengthening process for slide plate

Abstract

The invention relates to a laser strengthening process for a slide plate. The process comprises the steps of: A. treating the slide plate surface, and detecting the slide plate; B. coating the front and back sides of the slide plate with a laser light absorption coating; C. adjusting a tool according to a detection result, optimizing technological parameters, and fixing the slide plate on the tool; firstly carrying out laser quenching on each region of the back side discretely, with the back side quenching region area accounting for 1/3-2/5 of the total area of the slide plate back side; then the discretely quenching the front side of the slide plate; and D. performing detection. The laser strengthening process for a slide plate can conveniently correct the deformation of the slide plate. The overall deformation of a slide plate with thickness of less than 50mm is effectively controlled within 0.5mm, and the surface hardness of the slide plate is 52-56HRC, thus meeting use requirements.

Description

[0001] This application is a divisional application, the application number of the original application is: 201210166344.0, the application date: 2012-05-27, and the invention name is "Laser Strengthening Technology for Skateboard". technical field [0002] The invention relates to a laser quenching method, in particular to a laser quenching method for the surface of a slide plate. Background technique [0003] There are various types of skateboards used in steel mills, including single material and composite material, with different sizes and thicknesses. In order to meet the requirements of the steel plant environment, the skateboard requires quenching treatment on the front of the skateboard in the process formulation to ensure the surface wear resistance of the skateboard. The most important problem in the quenching of the slide plate in the usual quenching method is that the slide plate produces large deformation and distortion due to the input of heat. Make the plane ...

AI Technical Summary

Problems solved by technology

Because the thickness of the skateboard is too thin, generally less than 50mm, it is difficult to control the deformation of the skateboard by the ordinary laser quenching process, making the skateboard after laser quenching unusable. How to apply laser quenching to the strengthening of the skateboard, especially how to strengthen the skateboard with a thickness less than 50mm It is a problem to be solved by those skilled in the art to carry out laser quenching on the sliding plate to make it meet the requirements of use
