Abstract
The utility model relates to a graphite barrel heating furnace which is characterized in that the cavity of a tubular resistance heating tube is used as a heating chamber which is used in the heated graphite barrel heating furnace at high temperature. Heaters with adjustable temperature are respectively installed at the upper part and the lower part of the heating tube near the outside of both ends of the heating tube, and the adjustable temperature heaters are made to be vertical with the heating tube.
Description
Technical field of the present invention is: this graphite tube heating furnace be with the graphite tube body as heater, be used for high temperature heating.
Existing directly-heated type graphite tube heating furnace heats under high temperature (1500 ℃ to 3000 ℃) state, and heat-generating pipe is the length of heating evenly, depends on heating-up temperature basically.
As mentioned above, because existing directly-heated type graphite tube heating furnace at high temperature works, so, must be to the parts 7 of anchor stone ink cylinder, be used for cooling off to the wiring screw 8 of this graphite tube energising.Therefore, switch on when heating to heat-generating pipe 5, the two ends of heat-generating pipe 5 are except outside radiant heat, and also because above-mentioned cooling effect, the result makes the middle part temperature height of heat-generating pipe 5, along with then reducing gradually near two ends.Form a-b curve shown in Figure 2 a kind of fixing temperature analysis like that.
So evenly heating part shortens, when article to be processed passed through from stove fast and continuously, its intensification and cooling then changed only in this way a kind of form of the shape of temperature curve according to the thermograde of a among Fig. 2 and b respectively.
The invention solves the problem of above-mentioned existence, make even heating part elongated, and can change arbitrarily the shape of temperature curve. It is characterized in that: take the inner chamber of resistance tube heat-generating pipe as heating clamber, be used in the graphite barrel reheating furnace of high-temperature heating, outside near above-mentioned heat-generating pipe two ends, respectively at an upper portion thereof and at a lower portion thereof, by having filled the heater adjustable with the perpendicular temperature of this heat-generating pipe.
Below, with reference to drawing explanation one embodiment of the present of invention.
Fig. 1 is the profile of one embodiment of the present of invention, and Fig. 2 represents effect of the present invention, and the curve among the figure is the temperature curve of the article handled.
As previously mentioned, the temperature of graphite tube heating cooking stove in the past distributes or the temperature curve of the intensification → insulation → cooling of article to be processed, has only a kind of fixed shape of the a-b curve representative of Fig. 2.
In order to select the temperature curve of several shapes, the invention is characterized in: about near fixing heat-generating pipe 5 on two position component, by having adorned the adjustable heater 3 of several temperature, and make it vertical, it is clamped from both sides up and down with this heat-generating pipe 5.
In addition, be respectively that the middle part, horizontal side of heat-generating pipe 5 and the variable heater 3 of the left and right sides are carried out thermometric three positions, and these three positions are regulated heating current separately, thereby reach the purpose of regulating temperature.
In this example, variable heater 3 usefulness graphite heaters are done, and what the mensuration temperature was used is radiation thermometer, still, are not that qualification must these two kinds of things of usefulness.
Among the figure, the 1st, oven enclosure, the 2nd, the graphite heat-insulating material is filled between this oven enclosure 1 and the graphite box 4.The 6th, heating clamber is made of the inner chamber of heat-generating pipe 5.The 7th, heating graphite pipe 5 is fixed on parts on the oven enclosure.In addition, the 8th, the electrode terminal that water-cooled is used is contained in the two ends of heating graphite pipe 5, and the 9th, cooling tube is contained in the fixed part 7.
In heating furnace in the past, not by adorning temperature variable heater 3 shown in Figure 1, so, the temperature curve of the intensification → insulation → cooling of article to be processed, has only a kind of like this form of a-b curve shown in Figure 2, in contrast, because the present invention is provided with above-mentioned variable heater 3, so, heating current by any adjustment variable heater 3 and heat-generating pipe 5, can select the temperature curve of different shape, temperature curve C-d, C-e-d for example shown in Figure 2, perhaps a-f-d or the like.
Therefore, heating furnace in the past compares together, the above-mentioned performance that can in a big way, select temperature curve, and to high-temperature heating treatment, it is effective developing new application.
The simple declaration of drawing:
Fig. 1 is the profile of a graphite tube heating furnace embodiment of the present invention.
Fig. 2 is the temperature curve that is obtained by embodiments of the invention, and transverse axis is represented each position of heating furnace, and is corresponding with Fig. 1.

Claims (1)
- A kind of graphite tube heating furnace is that the graphite tube body is as heater, be used for the high temperature heating, because existing directly-heated type graphite tube heating furnace is at high temperature worked, so, must the parts of anchor stone ink cylinder be cooled off with the binding post that is used for to this graphite tube energising, make the middle part temperature height of heat-generating pipe, reduce gradually near the two ends temperature, so evenly heating part shortens, it is characterized in that: at the inner chamber with the resistance tube heat-generating pipe is heating clamber, be used in the graphite tube heating furnace of high temperature heating, near the outside at above-mentioned heat-generating pipe two ends,, and make it vertical with this heat-generating pipe respectively at an upper portion thereof and at a lower portion thereof by having adorned the adjustable heater of temperature.
