Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail by the following embodiments in combination with the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model provides a rapid annealing furnace, as shown in figure 1 and figure 2, include: the furnace comprises a frame 100, a furnace body 200, a furnace pipe 300, a heat insulation layer, a heating unit, a vacuum unit and an atmosphere unit, wherein the furnace body 200 and/or the furnace pipe 300 are/is slidably connected to the frame 100 so as to adjust the length of the furnace pipe 300 in the furnace body 200; a cavity 310 is formed inside the furnace 300, an opening is formed at one end of the cavity 310, which is far away from the furnace body 200, a first furnace door 321 is arranged at the opening, the first furnace door 321 is arranged inside the cavity 310 and is used for sealing the cavity 310, and the first furnace door 321 can slide along the cavity 310; a second furnace door 322 is arranged at one end of the furnace pipe 300 far away from the furnace body 200, and the second furnace door 322 is sleeved on the furnace pipe 300 and can slide relative to the furnace pipe 300; the heat-insulating layer is arranged inside the furnace pipe 300 and covers the cavity 310; the heating unit is used for heating the cavity 310, the vacuum unit is used for controlling the gas pressure in the furnace, and the atmosphere unit is used for controlling the gas components in the furnace. By adjusting the length of the furnace 300 in the furnace body 200, the volume of the heated furnace 300 is determined according to the requirement, so that the part of the heated furnace 300 which does not need to be heated is avoided, the energy is saved, and the efficiency is improved.
For example, when the whole furnace 300 needs to be heated, the furnace 300 is entirely located in the furnace body 200, and the first furnace door 321 and the second furnace door 322 are both located near one end of the furnace 300 far from the furnace body 200, so that a complete communicating cavity 310 is formed in the whole furnace 300, and all parts of the cavity 310 are heated. When the furnace 300 only needs to be heated by a half part, the first furnace door 321 and the second furnace door 322 are positioned in the middle of the furnace 300, wherein the first furnace door 321 divides the inner cavity 310 of the furnace 300 into two mutually isolated parts, one part close to the furnace body 200 is heated, and the other part far away from the furnace body 200 is not heated.
In one embodiment, in order to avoid heat overflow of the unheated furnace 300 during local heating, the rapid annealing furnace further includes a third door 323, the third door 323 is disposed at an end of the furnace 300 away from the furnace body 200, and the third door 323 is used to seal the entire cavity 310. The position relationship between the third door 323 and the furnace 300 is relatively fixed, that is, the third door 323 is only used for closing the opening of the cavity 310 in the furnace 300. For example, when the furnace 300 only needs half of the heating, under the effect of the first furnace door 321 and the furnace body 200, the temperature of the heating part cavity 310 rises, meanwhile, the heat insulation effect of the first furnace door 321 is limited, the temperature of the unheated part cavity 310 also rises slightly, but the temperature of the unheated part cavity 310 still is at a higher temperature under the high temperature condition, if the third furnace door 323 is not arranged, the heat can be directly overflowed and dissipated to the environment, so that the heat loss is caused, and even the production accident is caused.
Similarly, in order to avoid the overflow of heat of the furnace pipe of the unheated part during the local heating, the rapid annealing furnace further comprises a heat insulation assembly, the length of the heat insulation assembly is adjustable, the length of the heat insulation assembly is equal to the length of the furnace pipe which does not enter the furnace body, and the heat insulation assembly is wrapped on the furnace pipe. For example, the heat insulation assembly is a plurality of heat insulation tiles, and the number of the heat insulation tiles is adjusted according to the length of the furnace pipe exposed out of the furnace body so as to cover the exposed furnace pipe part and prevent heat from overflowing.
In one embodiment, in order to improve the uniformity of heating inside the furnace pipe during heating, the rapid annealing furnace further comprises a rotating mechanism, and the rotating mechanism drives the furnace pipe to rotate along the axis of the furnace pipe. Further, in order to reduce the influence of rotation on the material to be annealed, the rotating mechanism is an intermittent rotating mechanism, for example, the intermittent rotating mechanism comprises a cam plate and a driven rod, the driven rod comprises a cross-shaped connecting part and a mandrel, the cross-shaped connecting part and the mandrel are fixedly connected into a whole, the connecting part abuts against the cam plate, the mandrel is connected to the furnace pipe, and the mandrel rotates to drive the furnace pipe to rotate along the axis of the mandrel. The cam disc is provided with a stroke section and a non-stroke section, and when the connecting part is abutted against the non-stroke section, the cam disc rotates and cannot drive the connecting part to rotate; when the connecting part is abutted against the stroke section, the cam disc rotates to drive the connecting part to rotate. It should be noted that, in the rapid annealing furnace provided with the rotating mechanism, the furnace pipe should be a revolving body such as a cylinder, and the furnace pipe does not interfere with the furnace body in the revolving manner.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
