Description
Technical field
The invention belongs to technical field of heat treatment equipment, particularly relate to a kind of oil removing annealing and to turn blue full automatic treatment production line.
Background technology
In prior art, the key improving compressor efficiency reduces its open circuit loss.Open circuit loss is mainly iron loss, and iron loss is that magnetic hysteresis is damaged and eddy current damages sum.When frequency is fixed, eddy current damages and is directly proportional to silieonized plate thickness square, and eddy current damages that to damage key with magnetic hysteresis relevant with materials microstructure characteristic (carbon content, silicon content, organize grain size and organize internal stress etc.).Thermal treatment after silieonized plate cold-working processing is the key ensureing its tissue characteristics.The soft magnetic materials such as electro-magnetic steel plate, the magnetic properties such as its magnetic permeability, coercive force and magnetic hysteresis loss have stronger structure sensitive properties, the any stress produced in cold working process all makes its magnetic worsen, in order to obtain high magnetic, siliconized plate should be that impurity few (particularly reducing carbon content), crystal grain are large, unstressed.Therefore the subsequent heat treatment art breading that necessitates of destressing.
Existing silieonized plate adopts well formula clock hood type furnace to produce, shortcoming is that temperature uniformity is very poor, production efficiency is low, labor strength is large, the product dealt is often a collection of all more or less exists certain difference, along with the demand in market increases, the throughput of well formula clock hood type furnace originally has not reached far away and require that.On existing market not by oil removing, to anneal and three techniques of turning blue combine and are made into a full automatic production line of independence.Such as: application number is that the application documents of ZL201310023407.1 disclose a kind of vertical continuous annealing furnace and to turn blue device and technique of turning blue thereof, setting is turned blue medium station, be communicated with rapid cooling section, overaging section, eventually cold section of burner hearth by medium pipeline, the opening degree of regulating and controlling valve, diffusion valve, regulates rapid cooling section and/or overaging section and/or whole cold section of burner hearth furnace gas oxygen level 0.03% ~ 1.00%.The present invention utilizes existing vertical continuous annealing furnace, only need increase the device that turns blue, the annealing of blue steel strip, two operations of turning blue once be completed in vertical continuous annealing furnace.But this is simply to be superimposed by two function devices, does not meet the needs of whole thermal treatment process.
Summary of the invention
The problem to be solved in the present invention is that existing well formula clock hood type furnace is heat-treated shortcoming to comprise temperature uniformity very poor, and production efficiency is low, and labor strength is large, can not meet the present market requirement.
In order to solve the problems of the technologies described above, the invention provides following scheme: oil removing annealing is turned blue full automatic treatment production line, comprise transporting mechanism, heat treatment mechanism and controlling organization, transporting mechanism comprises pusher transfer roller, transmits step-down gear, travelling belt and charging tray, pusher transfer roller drives travelling belt to move, charging tray installed by travelling belt, transmits step-down gear and be arranged on pusher transfer roller; Heat treatment mechanism comprise material loading platform, except oil oven, First Transition room, annealing furnace, leer, the second transition chamber, type steam blueing furnace, the 3rd transition chamber, air-cooled, and material loading platform, except oil oven, First Transition room, annealing furnace, leer, the second transition chamber, type steam blueing furnace, the 3rd transition chamber, air-cooled be communicated with in turn; Controlling organization comprises central control cabinet and display screen.Utilize technique scheme, the rotor initial stage finished parts disposable thermal process of producing can be completed.Save artificial intensity, enhance productivity, reduce the otherness between different batches part simultaneously, increase interchangeability of parts.Concrete mode is: workpiece is delivered to corresponding position by transporting mechanism, heat treatment mechanism at workpiece through out-of-date, successively corresponding thermal treatment is carried out to it, controlling organization overallly can control travelling speed and the residence time of whole workpiece, also control the various processing parameters of whole heat treatment mechanism simultaneously, ensure that staff can check whole heat treated related data at any time.Concrete processing mode is: workpiece enters except oil oven carries out oil removing by material loading platform successively, then enter First Transition room to carry out cooling or drying, then enter annealing furnace and carry out anneal, enter leer subsequently to cool, then the second transition chamber is entered, enter type steam blueing furnace subsequently and carry out process of turning blue, finally enter the 3rd transition chamber, workpiece exports laggard inlet air cold bench and carries out last cooling and air-dry.
The specific workpiece that machine rotor-stator is such, actual treatment technique should be undertaken by four stages: first, last process remains in the oil stain on rotor-stator, dirt may be formed and to lamination carburizing between lamination during annealing, (coercive force increases to cause magnetic property to reduce, magnetic permeability reduces), therefore before annealing, oil removing is required, and this can evaporate by making 400 DEG C time oil stain and burning has come; Secondly, under protective atmosphere, (DX gas) carries out annealing to eliminate rotor-stator lamination cold working stress, improves the weave construction of siliconized plate, recovers the original ferromagnetic characteristic of siliconized plate (magnetic induction density is high, low iron loss); Make burr passivation, improve the planarization of siliconized plate, electro-magnetic steel plate stress relief annealing generally adopts the top temperature that is about 850 DEG C that α=γ phase transformation does not occur, and siliconized plate is by the impact of its surface coating material (borate) degree of oxidation, and annealing temperature is at about 750 DEG C; Again, produce internal stress for avoiding cooling rapidly and cause magnetic property to decline (to ensure to organize grain growth), 450 DEG C (750 DEG C slowly cool to 600 DEG C and should ensure its slow cooling speed) should be slowly cooled to the speed of 100 DEG C/h ~ 150 DEG C/h from 750 DEG C; Again; the workpiece of 450 DEG C proceeds to blueing furnace; under the forced convection atmosphere of DX gas+saturated steam; mainly be sheared section to siliconized plate to turn blue process; form the fine and close insulating protective film based on Z 250; short-term before preventing stator and rotor from assembling is got rusty, and becomes and improves the indispensable technique of electrical machine energy-saving performance.Finally, workpiece proceeds to air-cooled cooling fast below 450 DEG C.
Further, described transporting mechanism also comprises thermal insulation layer, and thermal insulation layer, by whole transporting mechanism all standing, can ensure the temperature environment of whole device like this, reduces the crystal variable effect that circumstance of temperature difference brings workpiece.
Further, described material loading platform is provided with loading/unloading platform, is convenient to the handling of workpiece.
Further, described charging tray is multiple being set up in parallel, and can place multiple workpiece so simultaneously and ensure can not paste tactile between each workpiece and affect heat treated effect simultaneously.
