Laser strengthening process of sliding plate

Abstract

The invention relates to a laser strengthening process of a sliding plate. The laser strengthening process of the sliding plate comprises the following steps: A, treating the surface of the sliding plate, and detecting the sliding plate; B, coating laser light absorbing coatings on the front surface and the back surface of the sliding plate; C, regulating a tool and optimizing process parameters according to a detection result, and fixing the sliding plate on the tool; firstly, performing laser quenching on various regions of the back surface discretely, wherein the area of the quenched region on the back surface accounts for 1 / 3-2 / 5 of the total area of the back surface of the sliding plate; and then performing laser quenching on the front surface of the sliding plate discretely; and D, detecting. The laser strengthening process of the sliding plate can correct deformation of the slide plate conveniently; the overall deformation of the sliding plate with a thickness of less than 50 mm is effectively controlled within 0.5 mm; and the surface hardness of the sliding plate is 52-56 HRC and meets the using requirement.

Description

technical field [0001] The invention relates to a laser quenching method, in particular to a laser quenching method for the surface of a slide plate. Background technique [0002] 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 fail to meet the technical requirements and use requirements, and it will be scrapped directly in serious cases, and the thinner the board, the larger the size and the more severe the deformation.

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
