According to the method and the device, disclosed by the invention, the steel plate can be immersed into the liquid with a certain inclination angle quickly and conveniently, the problem of great difference of cooling intensity between the upper plate surface and the lower plate surface caused by incapability of smoothly exhausting a large quantity of steam film on the lower surface of the steel plate after the steel plate is horizontally placed and immersed into the liquid can be solved, and the time difference between one side which is firstly immersed into the liquid and the side which is later immersed into the liquid when the steel plate is immersed into the liquid in a vertical way can be simultaneously reduced.
Description
Technical field
The present invention relates to the cooling field of heat-treatment quenching, particularly, what relate to is a kind of steel plate quenching method and corresponding equipment.
Background technology
Thermal treatment refers to the steel of austenite structure state cooling with suitable speed, obtains the process of intended tissue and performance.Steel except tissue with performance changes, is also accompanied by and produces cracking and distort in quench cooled process.If steel produces to ftracture to cause in quenching, scrap, hardening break can be avoided by suitable technique and quenching mode; Distorsion during quenching refers to the original size of workpiece or the variation that shape occurs when quench cooled, by which kind of measure (changing heating and process for cooling, installation way, quenchant kind, quenching mode), all cannot avoid the generation of distorsion during quenching, difference is the size that produces distortion.The steel plate here refers to that steel ingot forms certain thickness cuboid or other shape plate accessory through rolling or forging.
At present steel plate quenching be divided into roll rear press quenching and roll after or forge after reheat two classes of quenching.Rolling rear press quenching is the steel plate after hot rolling to be delivered directly to the mode with level on Special quenching machine carry out quench cooled, Special quenching machine is provided with pressure mechanism at upper face, the upper and lower plates face of steel plate is realized quench cooled under the state of spraying water up and down, for the little steel plate of thickness of slab, adopt which quench cooled can control amount of distortion within the specific limits, pressure limitation for the large steel plate of thickness of slab due to Special quenching machine pressure mechanism, controls the DeGrain of distorsion during quenching; Steel plate reheats quenching, generally adopts stove heating at the bottom of car type furnace or roller, then adopts driving and clamp specially that steel plate is transferred to and in quenching tank, carried out immersion liquid quench cooled.The liquid mode that enters that steel plate immersion liquid is quenched has two kinds, a kind of for being horizontal mode immersion liquid quenching between steel plate upper and lower plates face and quenchant liquid level, this mode quench cooled is because the steam film thickness that lower face produces is greater than upper face, cause the cooling intensity of upper face to be obviously greater than lower face, cause the amount of distortion of steel plate after quenching obviously to increase.Another kind of be vertical mode immersion liquid quench cooled for the upper and lower plates face of steel plate and quenchant liquid level, this mode is due to the cooling difference having reduced between upper and lower plates face, amount of distortion after quenching is relatively little, but this quenching mode need to be by 90 ° of the steel plate upsets of level heating before quenching, need to configure large-scale special overturn mechanism, there is to requirement in factory building height space, simultaneously because the first immersion liquid of wide plate face steel plate is poor compared with affecting greatly the consistence of plate face quality cooling time on one side with rear immersion liquid on one side.
Through prior art literature search is found, author Wolfram Schupe, Holger Kehler, < < efficient steel plate quenching-tempering heat treatment process > > (2010:614-617) article that Wang Peizhong etc. delivers at " the 6th Chinese World Iron & Steel conference collection of thesis ", introduced a kind of fixed quenching press, this quenching press can support the use with stove at the bottom of periodic roller, the block plate of at every turn quenching, steel plate is transported in quenching press after coming out of the stove, then by clamping tightly, water sprays to steel plate above steel plate and below by nozzle.By Control Nozzle, in edges of plate and middle part, form different water spray districts, in conjunction with steel plate, be clamped in rigidly in quenching press, can guarantee that steel plate has good planeness, particularly steel sheet.For this object, water spray mode must be the whole surface of steel plate of uniform fold, and this needs the best configuration of nozzle and the stable supplying of high pressure water.Due to the restriction of steel plate upper and lower plates face holding force, this quench cooled mode is to controlling large thickness steel plate distortion poor effect.
