Laser strengthening process for effective control of quenching deformation of sliding plate

Abstract

The invention relates to a laser strengthening process of a sliding plate. The process comprises the following steps: A, conducting surface treatment on a sliding plate and detecting the sliding plate; B, coating a laser light absorption paint on both sides of the sliding plate; C, adjusting tool and optimizing process parameters according to the detection results, and fixing the slide plate on the tool; carrying out laser quenching on each region of the back side in a scattering manner, wherein the quenching area on the back side accounts for 1 / 3 to 2 / 5 of the total area of the back side; and carrying out laser quenching on the right side of the sliding plate in a scattering manner; and D, conducting detection. The laser strengthening process of the sliding plate can conveniently correct the deformation of the sliding plate, and the overall deformation of sliding plate with thickness of less than 50 mm can be effectively controlled within 0.5 mm and the sliding plate has a surface hardness of 52-56 HRC, so as to meet the usage requirements.

Description

[0001] This application is a divisional application, the application number of the original application: 201210166344.0, the filing date: 2012-05-27, the name of the invention is "Laser Strengthening Technology of Skateboard". Technical field [0002] The invention relates to a laser quenching method, in particular to a laser quenching method for the surface of a skateboard. Background technique [0003] There are various types of skateboards used in steel mills, including single material and composite material, ranging in size and thickness. In order to meet the requirements of the steel plant's use environment, the front of the skateboard is required to be quenched in the process formulation to ensure the surface wear resistance of the skateboard. The main problem of the common quenching method in the quenching of the sliding plate is that the sliding plate is deformed and twisted due to the input of heat. Make the plane fail to meet the technical requirements and use requireme...

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
