Description of the Invention: [Technical Field] The present invention relates to a high temperature furnace for annealing a metal sheet joint, which has an annealing base and a supporting device which is spaced apart from the annealing base Forming a space for coaxially receiving a metal foil joint member, having a protective cover, comprising a dome-shaped outer casing and a dome at the top end of the outer casing, coaxially surrounding the annealing base and the a support device connected to the -new gas supply line and the protective gas discharge tube with a material seal between the annealing base and the protective cover, and with a fresh, 1U wire shield and spaced apart therefrom An interval. [Prior Art] A steel transformer metal sheet having a weight ratio of G.5 i 3.5% - ♦ is typically required to be subjected to a high temperature treatment in a hood furnace. The material to be annealed is under the protective body of nitrogen and/or hydrogen. In the protective cover, the light intensity is greatly increased by the first class (:. Under the high temperature, the essential strength of the Wei fire material will be greatly reduced' The plurality of metal sheet joints including the substantially wound steel strip are each supported on a supporting device, wherein the supporting device is supported on the annealing base by a load-dissipating (1〇ad-di=ating) manner, or penetrates The U-annealed wire is located on the basis of _. It is known that the high-temperature furnace of this type is especially supported during the annealing of the plate joint for the annealing pedestal along its center: square === metal sheet joint, in the lower area of the addition: Both of them are awarded the reward of gold. For the height of the joint piece, if the two metal sheet joints are supported by the towel-strips coaxially - corresponding support, tens of thousands of "Wanwu multiple upper joints heating" =Compared:: The king wants to, the upper joint or the square joint will make the bloodwork reach the joint, so the next *, the final temperature, and therefore the corresponding weakened magnetic 201040287 characteristics. (4) fire secret Any improvement is provided in this regard from the basis of the Society of Touch. In addition, in order to introduce the protection along the center, the protection method of the tactical _ _ 1 will be the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Therefore, «η, αμΪ according to the purpose 4, Wei-# _ part of the d-type "metal slab joint annealing high temperature furnace, so that the material to be annealed can be uniformly heated to high processing temperature in the gas environmental protection towel to ensure A transformer sheet made of steel having a fineness of 3.5% of the average sentence is provided by the spacer surface of the supporting device to compensate for the surface of the dome. The reason for the foregoing object is that the protective cover is determined by the vertical spacing. At least one-quarter of the surface between the axial jackets. From the beginning of the month, it has been found that additional light-radiation heat is supplied to the material to be annealed in the upper region through the dome of the protective cover, so that it is used for - a single metal sheet is attached to the n-piece annealed "storage towel, the heating of the metal sheet joint is faster in the tens of thousands of regions than in the lower region. The one will be coaxially arranged in one of the other = On the support device The second or more metal sheet joints may have a larger amount of light-radiating heat applied thereto during the upper or uppermost period. To compensate for the varying heat of the wire shield, the wire shield may be lengthened. Between the annealing pedestal and the (lower) sheet metal joining member, the supporting surface is disposed between the surface, and the protective sheath is provided in the region to provide at least three-quarters of the surface of the dome: Radiating the surface so that a sufficient amount of heat can be supplied to the material to be annealed in the area under the protective cover to at least partially compensate for the heat supplied in the area above the protective cover. Based on the method, it is thus ensured that The material to be annealed is heated to the processing temperature substantially uniformly 201040287. In order to pass through the protective cover, in the surface area of the supporting device, a radiation surface corresponding to one of the m dome radiating surfaces is equivalent to the annealing surface. The vertical spacing of the pedestals must be at least equal to the surface of the dome. However, this does not take into account the heat caused by the annealing base. For this reason, it is recommended that the surface of the sleeve portion, which is equivalent to the vertical spacing of the placement surface of the child, be made larger than the surface of the 贞. Increasing 5 to 2 G% is generally sufficient to compensate for the heat lost through the annealed susceptor. In order to greatly suppress the heat dissipated through the annealed susceptor, the annealed pedestal may be composed of mineral wool which has a significantly higher thermal insulation value than a typical refractory concrete slab. However, the larger load cannot be dissipated through the annealed base formed by a mineral wool. To this end, the carrier will penetrate the mineral wool to form an annealing pedestal and be supported on the foundation of the furnace for dissipation. In order to ensure excellent thermal insulation by means of the annealed pedestal, the mineralization of the mineralized cotton base is equivalent to at least one third of the diameter of the protective cover, preferably one-half. If the peripheral seal between the annealing base and the protective cover is made airtight, the protective gas supply line has a plurality of discharge ports distributed around the periphery of the protective cover, and the protective gas discharge pipe has a central penetration Annealing one of the exhaust gas lines of the susceptor is particularly excellent in terms of the protective gas guiding device because the outer layer of the Wei fire base and the inner surface of the fresh-keeping cylinder are uniformly heated. The heated shielding gas will flow through the outer hot foil joint region and be supplied through the cooler region in the interior of the foil joint to the exhaust conduit that is directed centrally through the annealing susceptor. In order to heat up the material to be read, which is subject to change in the height of the secret, the further step may include, after the addition, the twisting power which is gradually decreasing with height is applied to the preservation, so that the The towel has a higher heat supply' and ensures improved heating of the material to be annealed. For this reason, in the cover of the 201040287 cover with the _(4) device, the heating unit separation section capable of each actuation can be set. Preferably, the one-watt heating type fresh towel '峨n' is placed in the area between the social filament and the supporting surface of the supporting material to be annealed material disposed above the annealing base. BRIEF DESCRIPTION OF THE DRAWINGS The main content of the present invention will be shown in the drawings. In the drawings: Figure - in a schematic longitudinal section, a high temperature furnace according to the invention with a gas heating heating hood; Fig. 2 shows a high temperature according to the invention according to Fig. 1 - an electric heating heating hood Furnace diagram. [Embodiment] According to the drawings - and Fig. 2 (the high temperature furnace is based on the furnace foundation i, the furnace base i supports-annealing the susceptor 2, and the support device 3 can penetrate the annealing pedestal. The support device 3 is designed according to a specific embodiment of the second embodiment for receiving the two metal thin plate joints 4, which are each on the (10)-support_5 and one of them is located on the other tens of thousands. To implement the metal thin plate joint 4 Annealing can be achieved by the protective cover 6 surrounding the 'and the outer cover of the protective cover 7 · the connection between the furnace base 1 and the annealing base 2' is assisted by the arrangement of the flange 8 and the ring seal 9 The end of the dense land. The code = the ground, and / money read Wei body, the shaft - protection New Zealand supply pipeline (7) for the protection of the mouth around the protective cover 6 distribution of a number of outlets U 'make this = vine body can be in the jacket 7 Between the annealing base 2 and the casing 6 are recorded in the casing 6, and can be discharged along the center and the ground through the exhaust gas recording 12 of the annealing base 2. The heating cover 13 is placed to heat the casing. An annealing material, the heating cover is based on a plurality of burners 14 of the t-side material, and each of the individual heating zones is provided according to FIG. Section 15 consists of an electric heating unit. Yes, I can add a fresh element 'generally through the field cover and emit light light', and scale annealed material. Adding fresh 6 can not only provide light shot of its jacket 7 201040287 The surface may also use its dome 16 and also achieve joint heating via the dome surface to the area of the upper sheet metal joint 4. To compensate for this, the heat in the upper area of the cover 6 is heated. The annealing base 2 and a lower metal sheet joining member 4 are lengthened by the outer sleeve 7 in the region between the seating surface 17 of the supporting device 3. A structure can be formed to vertically space the supporting device 3 seating surface 17 away from the annealing base 2 The jacket portion of the protective cover 6 having a surface corresponding to at least four knives of the surface of the dome, preferably the surface of the holstered dome, is considered to pass through the anneal base 2 The additional heat loss 'the side section can be greater than the dome area by 5 to 2 (%). Therefore, the contact surface for heating the T-metal thin-film joint 4 can be obtained, and the light-emitting surface can be adapted to The upper metal sheet joint member 4 uses a simple surface, and the average sentence is heated by a gold The thin plate joint member 4 has the advantage of aligning the material properties caused by the annealing. To suppress the heat dissipation caused by the annealing base 2, the annealing base can be composed of mineral fibers having good heat insulating properties, which is equivalent to The protective cover 6 has a height of at least one-half of the diameter of the outer casing 7. However, one of the annealed bases 2 composed of mineral fibers cannot disperse the ants formed by the material to be annealed to the miscellaneous base, and the sulphur metal thin plate joint 4 The support device 3 itself needs to be supported on the base of the furnace. In order to maintain uniform heating of the metal thin plate joints 4, the protective cover 6 can be applied with different heating along its length. For this reason, the gas heating device of the figure 14 is located below the placement surface 17 of the lower metal sheet joint member 4. According to Fig. 2, the respective independent sections 该 of the electric heating unit can be actuated to ensure that, for example, depending on the height, Change the heating power. Of course, the present invention is not limited to the specific embodiments illustrated in the drawings. Therefore, the furnace can be designed to heat only a single sheet metal joint 4 or more than two metal sheet joints 4. When a single sheet metal joining member 4 is heated, the mounting surface 3 of the supporting device 3, which is selected as a function of the dome surface, is vertically spaced from the annealing base 2, which prevents the height of the viewing position from unevenly heating the sheet metal joint.
