Gate 5b is placed in locating part 6 from rear (from upper number second in figure).
In the hot air type heat-treatment furnace of the metal tape for the nozzle for having general Convective Heating formula, from slab to thin
Plate is carried out in the case of continuously handling, in the state of the temperature and wind speed for maintaining that slab can be made to rise to defined temperature
When conveying thin plate, the temperature of thin plate excessively rises to deviate from the condition of product.For example, it anneals if purpose processing is annealing
Degree is excessive.
In order to prevent the situation, it is usually operated in a manner of reducing the wind speed of the heat gas from nozzle, however
In the case where excessive temperature rise also nonetheless occurs, need to reduce in-furnace temperature.Time needed for the cooling is according to processing
Condition and it is different, maximum be even up to a few houres, during this period by metal tape can not become product so as to cause to waste.
When being cooled down, usually conveying simulates material or adds refrigerating function to the circulating path of furnace temperature to reduce furnace temperature, but generation time
Waste and the energy waste.
It should be noted that as general cooling rate, -100 DEG C/h is up in the stove for using refractory brick, if
The only stove of ceramic fibre without using brick, then be -150 DEG C/h.In addition, if material is different, the type of processing is different, band is handled
The temperature of plate is sometimes for 200 DEG C or more of decline.
Moreover, the inventor of the gate mechanism 1 of this strip-shaped piece processing equipment confirmed between nozzle 4 and metal tape 2
Effect during gate 5 is set, i.e., using the metal that annealing grade can be caused excessive if by the hot wind from nozzle 4 directly injection
Band 2, it is thus identified that when being blocked between metal tape 2 and nozzle 4 by the gate 5 of the gate mechanism of the strip-shaped piece processing equipment of the present invention
Pass through the surface temperature of the metal tape 2 in multiple nozzles 4.For confirmation hot air type heat-treatment furnace 1 from top to bottom
On the direction of travel of the metal tape 2 of traveling there is Pyatyi nozzle and block gate between each nozzle and metal tape.Moreover,
Connect in the metal tape of the heat treatment under needing lower temperature with the heat treatment being carried out under higher temperature and first metal tape
Connect fashionable, the first position in the front advanced correspondingly with it and Pyatyi gate is made once to be moved to nozzle of going forward side by side.
Fig. 5 shows its result.The longitudinal axis represents the surface temperature of metal tape, and horizontal axis represents the displacement distance of metal tape,
The range setting Pyatyi gate of 2m to 10m.Apart from the position of the lower section of nozzle about 11m, in the feelings for declining Pyatyi gate
It under condition, confirms compared with situation about not declining, the surface temperature of metal tape about declines 60 DEG C.
The gate mechanism of strip-shaped piece processing equipment according to the present embodiment, multiple nozzles 4 of blowing hot air are along gold
Belong to the width direction of band 2 and be set to the entire width of metal tape 2, therefore can be sprayed to the whole region of the metal tape 2 of traveling
Blowing hot-air, so as to implement substantially uniform heat treatment to the whole region of metal tape 2.In addition, gate 5 by mobile device 7 and
Second between multiple nozzles 4 and metal tape 2 is not blocked to the first position blocked between multiple nozzles 4 and metal tape 2 or
Movement is put, therefore easily can heat in blowing hot air and block hot wind and inhibit to switch between heating.At this point, gate 5
With being moved together along direction of travel, therefore it can be made instantaneously to move along the bar 9 of direction of travel.Therefore, even if thickness not
Same metal tape 2 is continuously traveling, and also can rapidly change the position of gate 5.
In addition, nozzle 4 is in the slit-shaped along width direction, therefore can be in the metal tape 2 of traveling and slit-shaped
The opposed region of nozzle 4 be reliably heat-treated.In addition, nozzle 4 be provided at spaced intervals on direction of travel it is multiple,
The gate 5 being arranged in correspondence with each nozzle 4 can also respectively individually moved, thus by with each nozzle 4 accordingly
Gate 5 is configured in first position or the second position, the injection amount of hot wind being blown to the metal tape 2 of traveling can be changed.
In addition, being provided with gap S between gate 5 and nozzle 4, nozzle 4 is not blocked by gate 5, therefore is blown from nozzle 4
Hot wind spread in stove.Therefore, it is possible to not maintain in-furnace temperature to 2 blowing hot air of metal tape.Even if in addition, gate 5 to
The first position blocked between nozzle 4 and metal tape 2 is moved also from 4 blowing hot air of nozzle, so even being shared in all nozzles 4
In the case of hot wind piping, due to plug nozzle 4 hot wind will not be moved to other 4 sides of nozzle.Therefore, even if lock
Door 5 is blocked between nozzle 4 and metal tape 2, can also inhibit the influence of the wind pressure to other nozzles 4.
In addition, its movement when declining from the second position of gate 5 is limited by locating part 6 so as to be configured at first position,
Even if therefore also gate can be configured at same position for example in the case of 9 hot-stretch of bar.Therefore, it is possible to more reliably
Block the injection of the hot wind to metal tape 2.
In addition, gate 5 has the multiple planks 11 divided in the direction of the width, above it between receiving hot-stretch
Gap surplus C, therefore with connecting and can reduce compared with gate that a component is formed curved caused by heat in width direction
Bent, concave-convex such deformation.In addition, gate 5 has plank 11 and recess portion 14, so as to make the space between them as empty
Air bound thermosphere plays a role.Plank 11 can be towards nozzle 4 with either one in recess portion 14, but will preferably absorb hot-drawn
The plank 11 stretched is configured at the high temperature side that the hot wind from nozzle 4 is in direct contact when being moved to first position gate 5.This
Sample one, recess portion 14 is separated by air heat-insulation layer, therefore is unlikely to deform, and thermal deformation is not easy so as to whole as gate 5.By
This, can keep the depth of parallelism between the face of metal tape 2 and the face of gate 5 (plank 11), avoid the thermal deformation due to gate 5 and
It contacts with each other or Temperature Distribution is deteriorated.
In the above-described embodiment, nozzle 4 is illustrated, but can also make for example multiple circular holes in the example of slit-shaped
The nozzle of shape forms row and is set along the width direction of metal tape.
The traveling of metal tape 2 can also ordinatedly can also carry out first position and the second position with this from the bottom to top
It replaces.In addition, heating target object can also be the object other than metal tape 2.
In addition, the quantity of nozzle 4 being provided spaced apart in the up-down direction is not limited to the above embodiment.
In addition, the above embodiment is used to that the present invention to be made to be readily appreciated that rather than for limiting, explaining the present invention.This hair
It is bright within the scope of its spirit, it is of course possible to change, improve, and the present invention include its equivalent.
