Technical field
The present invention relates to a kind of laser-quenching method, especially a kind of laser-quenching method of sled surface.
Background technology
Steel mill is varied by slide plate kind, have single plant material and composite minute, differ in size, thickness is not etc.In order to reach the requirement of steel mill's environment for use, slide plate all requires slide plate front to do quench treatment in technology establishment, to guarantee the surface abrasion resistance of slide plate.Common quenching method topmost problem in to the quenching of slide plate is that the input due to heat makes slide plate produce large distortion, distortion.Make it plane and do not reach technical requirements and service requirements, directly scrap, and plate is thinner when serious, size more gross distortion is more severe.
Laser quenching application laser quenching technology, is the laser beam rapid heating steel material surface utilizing after focusing on, and it is undergone phase transition, and forms the process of martensite quench-hardened case.The power density of laser quenching is high, and speed of cooling is fast, does not need water or wet goods heat-eliminating medium, be clean, quenching technology fast.Because the thickness of slide plate is too thin, be generally less than 50mm, common laser-quenching technique is difficult to control the deflection of slide plate, slide plate after laser quenching cannot be used, how laser quenching is applied to the strengthening of slide plate, especially how the slide plate that thickness is less than to 50mm carries out laser quenching makes it meet service requirements, is the problem that those skilled in the art need to solve.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly carries out laser quenching to sled surface, effectively controls the quenching strain of slide plate, makes it meet the laser reinforcing process of the slide plate of service requirements.
In order to solve the problems of the technologies described above, the laser reinforcing process that the invention provides a kind of slide plate comprises the following steps:
A. the surface of slide plate is processed, slide plate is detected;
B. at slide plate tow sides, apply laser light absorption paint;
C. according to detected result, adjust frock, Optimizing Process Parameters, is fixed on slide plate in frock; First the reverse side of slide plate is divided into a plurality of uniform regions, discretely the regional of reverse side is carried out to laser quenching, the area summation of controlling reverse side quenching region accounts for 1/3 to 2/5 of the slide plate reverse side total area; Then quenched in the front of slide plate discretely, until slide plate front all completes quenching, slide plate reaches level requirements or reverse side projection; If slide plate reverse side is protruding, after slide plate is cooling, remove frock, to the correction of quenching of the position of slide plate reverse side projection, until deflection is controlled in 0.5mm;
The fast-transverse-flow CO2 laser of take carries out lap connection scanning to slide plate as light source; Laser power is 1900W to 2300W, and absolute altitude is 260mm to 275mm, and spot size is 15mm * 1.8mm, and sweep velocity is 400mm/min to 500mm/min, and amount of lap is 2mm;
D. detect.
In order to improve the specific absorption of sled surface to laser, a kind of preferred technical scheme is: in above-mentioned steps B, the thickness of dope layer is 0.25mm to 0.35mm.
In order further to improve the specific absorption of sled surface to laser, a kind of preferred technical scheme is: in above-mentioned steps B, the component of coating and weight percent content are silica powder: 90% to 97%, graphite: 1% to 3%, resol: 1% to 4%, molybdenum-iron: 1% to 3%, solvent is alcohol.In coating, the appropriate molybdenum-iron that adds can improve the hardness on quenching tail skid surface, and the coating of this composition has good flow, and it is convenient to apply, and coordinates above-mentioned laser-quenching technique method, can make the quenching effect of slide plate better.
For slide plate to be strengthened is successfully quenched, and obtain better quenching effect, a kind of preferred technical scheme is: above-mentioned steps A removes the dust on slide plate, greasy dirt, corrosion; Detect surface hardness and the deflection of slide plate.
In order to guarantee the quenching effect of slide plate, a kind of preferred technical scheme is: above-mentioned steps D detects sled surface hardness; Detect slide plate deflection; Slide plate be can't harm to dye-penetrant inspection.
In order better to deposit the slide plate after strengthening, a kind of preferred technical scheme is: after above-mentioned steps D, qualified slide plate is cleared up, surface oils, packing, warehouse-in.
Technique scheme of the present invention has the following advantages compared to existing technology: the laser reinforcing process of slide plate of the present invention is when carrying out laser quenching, first the reverse side of slide plate is divided into a plurality of uniform regions according to original deformation rule, discretely the regional of reverse side is carried out to laser quenching, it is 75% left and right of positive total deformation that the reverse side deflection of slide plate is controlled, now the front of slide plate is protruding, and reverse side tensile stress is even; Then by rule, quenched in the front of slide plate discretely, until slide plate front all completes quenching, now slide plate reaches level requirements or reverse side projection; As slide plate reverse side projection, after slide plate is cooling, remove frock, detect slide plate bulk deformation amount, then to corrections of again quenching of the position of slide plate reverse side projection, the limit correction limit measurement of quenching, until reach requirement.This technique is carried out after laser quenching in sled surface, can to the deflection of slide plate, proofread and correct easily, and the bulk deformation that thickness is less than the slide plate of 50mm is effectively controlled in 0.5mm, and the surface hardness of slide plate is 52～56HRC, meets service requirements.
