The specific embodiment
Now, example of the present invention is described with reference to the accompanying drawings.
Fig. 1 represents the 1st example of the heating means of sheet material of the present invention.This example uses heating furnace 1, heating furnace 1 is known roller-bottom type continuous furnace, promptly, inside at the body of heater 2 that is made of heat-barrier material is provided with roller path 3, by making the holding device 4 that keeps by 3 pairs of heating target things of roller path, continuously the heating target thing is burnt till (heating) constantly by in the heating furnace 1.
Itself also be the radiant panel retainer 9 that the holding device 4 of an example of the present invention has sheet material retainer 7 and radiant panel 8 is kept, this sheet material retainer 7 is that glass substrate 6 remains on hot blast is had on the base 5 in many holes by ground with the sheet material of heating target thing.The thickness that radiant panel 8 forms oxide-film by the surface is that the stainless steel foil of 50 μ m to 100 μ m constitutes.In addition, the width of radiant panel 8 is wideer than glass substrate 6, has glass substrate 6 height about half, relatively is maintained below the central authorities of deflection glass substrate 6.The top of the holding device 4 of heating furnace 1 is provided with hot air blow port 10, blows out hot blast as shown by arrows downwards, by the gap of glass substrate 6 and radiant panel 8, and the straight downside that blows to roller path 3 downwards.The hot blast that blows to the below is subjected to being configured in the heating of the heater (thermal source) 11 of roller path 3 downsides again, be directed to the top of heating furnace 1 by the circulation stream 13 that is located at the side in the body of heater 2 by fan 12, blow out downwards from blow-off outlet 10 again by filter 14.
Fig. 2 represents the detailed structure of holding device 4.Sheet material retainer 7 is held in a plurality of glass substrates 6 settings parallel to each other.In addition, radiant panel retainer 9 is erected into radiant panel 8 relative with glass substrate 6 respectively in the both sides, front and back of the glass substrate 6 at the central authorities of adjacent glass substrate 6 and two ends, that is to say, radiant panel 8 is held in parallel with glass substrate 6.
The thermal effect that adds of the glass substrate 6 that used behind above-mentioned heating furnace 1 and the holding device 4 then, is described.
The Temperature Distribution of the glass substrate 6 when utilizing hot blast heating certain hour in the model after at first, Fig. 3 is illustrated in heating means of the present invention are simplified.Among Fig. 3, radiant panel 8 is to be configured between each glass substrate 6 and both sides with hot blast downstream about 3/4ths relative forms of glass substrate 6.If to the glass substrate 6 of the normal temperature of configuration like this and radiant panel 8 in heating furnace 1 from above when blowing hot-air heats downwards, glass substrate 6 and radiant panel 8 just are subjected to the heating from the convective heat transfer of hot blast.
In the curve of Fig. 3, dotted line is represented the Temperature Distribution of radiationless plate 8 occasions.Hot blast temperature by glass substrate 6 heat absorptions descends, so as shown in the figure, the programming rate of the upstream side of glass substrate 6 improves, and upstream side just becomes high temperature more.In addition, represent to dispose the Temperature Distribution of radiant panel 8 occasions with solid line.In the occasion that disposes radiant panel 8, radiant panel 8 heats up because of the convective heat transfer from hot blast too, becomes radiation of high temperature plate 8 and carries out its heat is released to irradiation of electromagnetic waves.Glass substrate 6 not only is used to be heated from the convective heat transfer of hot blast, and utilizes the radiation of radiant panel 8 to obtain heating, so the part relative with radiant panel 8 only compares the temperature height from the convective heat transfer occasion of hot blast.So, if only at the low downstream part of hot blast temperature configuration radiant panel 8, what the temperature that then can remedy glass substrate 6 upstream sides rose and the temperature in downstream rises is poor, the temperature difference about can reducing.
In this example shown in Figure 2, radiant panel 8 not only is not configured in the upper end of glass substrate 6, nor is configured in the part relative with the lower end.This because: owing to below glass substrate 6, dispose heater 11, thus approach to be subjected near the lower end of glass substrate 6 of heater 11 to heat up from the radiant heat of heater 11, need be from the radiant heat of radiant panel 8.That is, radiant panel 8 disposes in that the hot blast downstream of glass substrate 6 is only relative with the part of stow away from heat, thereby can make the temperature differences in the glass substrate 6 become minimum.
Upper end when then, Fig. 4 represents that 4 pairs of glass substrates 6 of holding device with Fig. 2 heat and the variations in temperature of bottom.Heating furnace 1 is divided into a plurality of cells at the throughput direction of holding device 4, and the temperature that blows out of the hot blast in each cell is configured to uprise gradually.Dot bottom variations in temperature among Fig. 4, be illustrated in the bottom variations in temperature of radiant panel 8 being installed the glass substrate 6 of back state with solid line at the glass substrate 6 that radiant panel 8 is taken off the back state.Radiant panel 8 have or not the upper end temperature that can make glass substrate 6 different.As can be seen from the figure, when hot blast blow out temperature more than 350 ℃ the time radiant panel 8 begin to tell on, temperature is high more, it is just good more that the upper end of glass substrate 6 and the temperature difference of bottom reduce effect.This is that radiant panel 8 produces effect especially for the heating of high temperature more than 400 ℃ because the relation of radiant heat and temperature is the cause of biquadratic ratio.
In addition, in this example, as shown in Figure 5, also radiant panel 8 can be remained on the glass substrate 6 every 1 ground, that is, arbitrary that radiant panel 8 only is configured to the surface of 1 glass substrate 6 or the back side is relative.This is because transmit the little occasion of heat difference in the little convection current of glass substrates such as occasion about in the of 6 of hot blast temperature decline, also can reduce the photothermal cause of radiant panel 8.
Because the radiant panel retainer 9 of this example is clipped in radiant panel 8 between pillar 18 and the pressing plate 20 and carries out clamping, therefore, even the material of radiant panel 8 is the low materials of mechanical strength that are made of stainless steel foil, also can be maintained securely.In addition, even change the length up and down of radiant panel 8 and the height that is kept, radiant panel retainer 9 also can keep radiant panel 8 easily and securely, so can easily change the length up and down of radiant panel 8 and the height that is kept according to various conditions such as the physical property of the temperature of hot blast and air quantity, glass substrate, so that the temperature difference of glass substrate 6 minimizes.
In addition, Fig. 6 represents the 2nd example of the heating means of sheet material of the present invention.Among Fig. 6, for the structural element of the 1st example identical function, put on same-sign and omit explanation.
The heating furnace 1 ' of this example constitutes hot blast and blows on the glass substrate 6 to horizontal direction.The retaining member 4 ' that utilizes roller path 3 to carry in heating furnace 1 ' has: flatly and spaced-apart certain intervals ground sheet material retainer 7 ' that a plurality of glass substrates 6 are carried out stacked maintenance; Between glass substrate 6, respectively radiant panel 8 is held in the radiant panel retainer 9 ' of level.
In this example, the effect of radiant panel 8 is also identical with the 1st example.In this example, because heater 11 is located in the circulation stream 13, so that radiant panel 8 is configured to is relative with the end of downstream side of glass substrate 6.In the heating furnace 1 ' that the hot blast level is blown out, also can vertically keep glass substrate 6 and radiant panel 8.
