The wind2 6 that the metallic object 50 that e Foerderanlage is over thermal treatment by the roller feeding unit 4 of supplying with metallic object 50 and downstream position at metallic object 50 travel directions winds up constitutes.
On the one hand, heating unit 1 usefulness whole section as shown in Figure 2 roughly becomes orthogonal cover case 17 to encase and seals, and the immigration mouth of metallic object 50 18 is provided with the sealing element (not shown) respectively with shifting out in mouthfuls 19.In cover case 17 metallic object 50 be heated to 200～600 ℃ high temperature be highly susceptible to oxidized because in cover case 17 and all be filled with H in the connected path 32
2Or N
2Deng reductibility or atmosphere of inert gases, so that metallic object can keep is not oxidized.
During the operation beginning, to the atmosphere gas H in the cover case 29 that reaches refrigerating unit described later in this cover case 17
2Or Ar metathetical occasion, for preventing blast, give earlier with rare gas element for example nitrogen replace and air got rid of, then with displacement nitrogen such as hydrogen.This kind method, when operation stops with H
2Also use from covering the occasion of getting rid of in the case.
As shown in Figure 3, have in the case 17 being the center by the metallic object of carrying 50 within it at cover, at above-below direction is to apply that desired pressure keeps the contact of continuous face with it and the carbon plate 20 that carries out clamping to this metallic object 50 on the thickness of slab direction, the laminated even plate 21 of the carbon of making by the good thermal conductivity material that is equiped with on carbon plate and the reverse side metallic object contact surface, and, also repeatedly putting respectively up and down in turn covered insulating electric heaters 23 and the thermal insulation material of establishing for the anti-heat radiation of well heater here 24 that constitutes by ceramic wool blanket etc. by heat-resistant insulation material 22 and with carbon plate 20 with metallic object 50 in its thickness of slab direction promptly from the above-below direction clamping device 25 etc. of clamping aptly.
Owing in the inboard of each pressing plate 26 lagging material 24 is set, the heat that electricradiator 23 is produced is cut off at this, so can make the thermosteresis of leaking to pressing plate 26 reach inferior limit.
Evenly plate 21 can make to the heat transfer of carbon plate 20 even.
The thickness of carbon plate 20 is preferably got the thickness that does not cause thermo-efficiency to reduce herein, for example gets 5～7 millimeters.
The pressure-producing part 27 of side guide 26 constitutes the pressing plate 26 that clamping device 25 is formed by for example heavy-walled carbon steel with pressing down upwards from the lateral of covering case 17, and Zuo Yong result makes in its thickness of slab direction of metallic object 50 upper edges and gives and required pressure from above-below direction like this.
With above structure, the heat energy of carbon plate 20 is reached on the metallic object 50 equably, metallic object is heated to specified temperature and cramping and unlikely generation distortion.
The pressure of this kind occasion can be too high, contacts just passable as long as make not produce the atmosphere gas-bearing formation and make them reach face between metallic object 50 and the carbon plate 20.Owing to will allow pressure-producing part 27 to move up and down, the top of cover case 17 will have flexible on above-below direction.
And, also can use moly-sulfide to make lubricant in order to prevent metallic object 50 scratches, also can carry out surface treatments such as TiC or TiN to carbon plate 20.
Meanwhile,, the heat that it took place is reached metallic object 50 by even plate 21 and carbon plate 20 be heated to high temperature to electricradiator 23 power supplies by supply lines 28.
At this moment, because metallic object 50 is that face contacts and direct heating with ceramic plate 20, its thermo-efficiency is very good.
Its temperature is more than the annealing temperature of metallic object 50, and the difference of complying with employed metallic substance is set in about 600～1200 ℃ usually.
On the other hand, refrigerating unit 2, as shown in Fig. 4 and Fig. 5, use the cover case 29 into rectangular cross sectional shape to encase airtightly with heating unit 1-sample ground is whole, the feeding mouth 30 of the heating of metal body 50 that transmits from heating unit 1-side is installed the sealing element (not shown) respectively with the mouth 31 that shifts out that it is shifted out.
Oxidized in order to prevent the metallic object 50 that is under the condition of high temperature in cover case 29 inside, fill H
2Deng reducing gas or N
2Deng rare gas element to form reductibility or atmosphere of inert gases.
That is and since metallic object 50 in air in about phenomenon such as oxidation stain that can cause more than 200 ℃, therefore in cooling, also be necessary to prevent oxidized, so in the cover case formation reductibility or atmosphere of inert gases.
And then, heating unit 1 shift out mouthfuls 19 with the feeding mouth 30 of refrigerating unit 2 between be connected with airtight connecting passage 32, owing to wherein being filled with reductibility or rare gas element, so the metallic object 50 of conveying can prevent oxidized in connecting passage 32.
Be the center from above-below direction with the metallic object 50 that is transferred in the case 29 by cover be the cooling jacket 34 etc. of the reverse side of the thickness of slab direction clamping face that sets gradually carbon plate 33 that contacts continuous clamping with its face and the clamping metallic object 50 that is positioned at this carbon plate 33.
Laterally alternately disposing dividing plate 36 along it in casing 35, these dividing plates 36 form refrigerant pathway each other, to carry out temperature control.
Though cooling agent circulates in this wise in refrigerating unit 2, but the material of metallic object 50 and each required crystal structure not merely rely on cooling agent, also to carry out circulation corresponding to the thermophore of necessary degree, change cooling temperature and speed by the computer of controlling according to the signal of temperature probe, keep preset time on the both fixed temperatures meaning ground of taking up an official post, thereby can at random adjust the crystal structure of metallic object 50.
Below, be described in detail for the action of the embodiment of above-mentioned formation.
At first, for example, the strip metal body 50 of thickness is wound into the roller shape with being heat-treated to a certain degree in advance.
For example, about 1～2 millimeter of the initial thickness of slab that uses carries out calendering described later (rolling) repeatedly with it, and thickness of slab becomes about 0.1 millimeter after the thermal treatment.
Then, band roller 9 is assemblied on the tensioning shaft 8 of roller feeding unit 4 of a part that constitutes e Foerderanlage 3, the front end of this metallic object 50 is successively by calender device 15, heating unit 1, arrival wind2 6 such as refrigerating unit 2 and reel fixing.
If all devices are started working, then metallic object 50 should sequentially lay out from band roller 9 under this state, and metallic object 50 is integrally carried to wind2 6.
During this period, metallic object 50 at first rolls processing along its thickness of slab direction plus-pressure between the working roll 16a of calender device 15, and produces work hardening.
Metallic object after the calendering processing 50 is imported heating units 1, in this heating unit 1, carry out the heat treated of metallic object 50, in refrigerating unit 2, carry out smooth constant temperature thermal treatment again, thereby make metallic object 50 stand successive thermal treatment.
In heating unit 1, make pressure-producing part 27 actions of a part that constitutes clamping device 25, cover the top of case 17 certainly and keep elastic force downwards to apply suitable slight pressure.
Thereby cover in the case 17 topmost and the pressing plate 26 repeatedly put of foot between apply small pressure, make to contact continuously clamping slidably at 20 mobile metallic objects 50 of carbon plate with two carbon plate faces and.
The adjustment of heat-up time in heating unit 1 is to be that the translational speed of metallic object 50 realizes by the velocity of rotation of regulating driving roll 11.
After this, shifting out of 50 self-heating apparatus 1 of the metallic object after the heat treated mouthfuls 19 shifted out and imported in the refrigerating units 2 by the connecting passage 32 that reductibility or atmosphere of inert gases filling are arranged, carry out constant temperature thermal treatment.
That is: in refrigerating unit 2, cooling agent or thermophore are flowed in each cooling room 37 in the cooling jacket 34 of the upper and lower settings of carbon plate 33, cold and hot according to it, the temperature that will be between carbon plate 33 moves slidably is than higher metallic object 50, directly cools off and carries out smooth constant temperature thermal treatment.
At this moment, owing to contact with 33 of carbon plates, can pass through carbon plate 33 and directly cool off, the cooling efficiency raising with metallic object 50 that heating unit 1 is in the same condition of high temperature.
Because cooling efficiency rises and can sharply cool off, especially as beryllium copper need from the annealing temperature more than 800 ℃ be quenched to below 700 ℃ always or as stainless steel from 1050 ℃ of occasions that are quenched to 200 ℃ always, can adapt to requirement.
The cooling temperature of metallic object 50, shifting out mouthful 31 places and can adjust to below 100 ℃ at refrigerating unit 2.
Like this, the temperature of metallic object 50 is in below 100 ℃, just is difficult to oxidized.
The temperature of the metallic object 50 by refrigerating unit 2 is owing to also more than 100 ℃, for anti-oxidation, similarly be filled with reductibility or atmosphere of inert gases with heating unit 1 in its cover case 29.
At this, though in refrigerating unit 2, pass through cooling agent as described above, singly be not to use cooling agent according to the material of metallic object 50 or the difference of desired crystal structure, can also there be thermophore to circulate corresponding to required degree.
Refrigerating unit 2 makes metallic object be cooled to specified temperature in the given time, and can at random keep, and is cooled to room temperature then.
By this controlled cooling, can adjust the crystal structure of metallic object 50 arbitrarily.
And then refrigerating unit 2 also can keep the operation of specified temperature and the cooling of formation stage repeatedly at the fixed time to metallic object 50, with the control device controlled chilling temperature of band computer and the variation of speed of cooling.
As mouthful metallic objects 50 of 31 outputs that shift out of the self-cooling set 2 of finished product, the take-up mechanism 6 by its downstream side in turn is wound into roller.
The processed plate 1 of reeling on wind2 6 for hope has the occasion of littler thickness, can carry out above-mentioned same heating, cooling operation repeatedly several times, to obtain desirable thickness of slab, for example 0.1 millimeter.
If in turn reel without wind2 6, also can cut into institute's measured length with cutter, transport to subsequent processing.
Though be to be illustrated in the above-described embodiments with regard to common single metallic object continuous heat treatment, be not limited thereto, also can heat the clad that carries out simultaneously with calendering and handle.
Promptly end, will be suitable for the laminated coincidence of laminal other kind of metal that clad handles thereon as the strip metal body of mother metal, with its integral body as metallic object 50.
So, it is carried to refrigerating unit 2 continuously from heating unit 1, carry out above-mentioned same processing.
That is, carrying out clad when handling, it must applied big pressure sending on layer direction when heating with metallic object.For this reason, increase the strength of the pressure-producing part 27 that constitutes heating unit 1, use much larger than aforementioned heat treated pressure clamping along laminated direction.
In this occasion, owing on the pressure-producing part 27 the elastic force effects such as spring of above-below direction are arranged, not clamping securely with metallic object 50 but allow slip.
The Heating temperature of this moment is the temperature setting that obtains on the master alloy layer at the mother metal of metallic object 50 and other kind of metal and junction surface thereof according to the thermodiffusion phenomenon, and should be lower than the melting temperature of mother metal and other kind of metal respectively.
Because the arranged outside at each ceramic plate 20 has even plate 21,,, also can on the plane of metallic object 50, apply even load because the effect of even plate 21 is arranged just in case loading is unevenly arranged in pressing plate 26 1 sides.
Like this, in the present embodiment,, in heating of metal body 50, can provide big pressure, so can make metal clad board continuously owing to increased the pressure of the pressure-producing part 27 of heating unit 1 significantly.
