Description

Technical Field

[0001] This utility model relates to the field of silicon-chromium alloy processing technology, specifically to an annealing furnace for decarburizing silicon-chromium alloys. Background Technology

[0002] The main function of an annealing furnace is to change the structure and properties of materials through heating and controlled cooling processes. It plays an important role in various fields of application, improving product quality and performance. Silicon-chromium alloys require the use of annealing furnaces during processing.

[0003] Currently, existing annealing furnaces still have the following shortcomings: when changing materials, the furnace door remains open, causing the internal temperature to dissipate outwards. This heat is wasted, and how to utilize this heat to preheat the materials to be processed is a problem that urgently needs to be solved by those skilled in the art. To address this, we propose an annealing furnace for the decarburization of silicon-chromium alloys. Utility Model Content

[0004] The purpose of this invention is to provide an annealing furnace for decarburizing silicon-chromium alloys, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an annealing furnace for decarburizing silicon-chromium alloys, comprising:

[0006] An annealing furnace body is provided, with a furnace door installed on the furnace body. An air pump is fixedly installed on one side of the furnace body, and a first air guide pipe is fixedly installed on the air pump. An air suction hood is fixedly installed on the end of the first air guide pipe away from the air pump. A second air guide pipe is fixedly installed on the air pump, and a diverter pipe is fixedly welded to the end of the second air guide pipe away from the air pump. Two air inlet pipes are fixedly welded to the diverter pipe. A heat insulation box is installed on one side wall of the annealing furnace body, and two serpentine heat-conducting pipes are fixedly installed inside the heat insulation box. One end of each of the two serpentine heat-conducting pipes is fixedly connected to one of the two air inlet pipes. A heat-conducting plate is fixedly welded to the opposite side of each of the two serpentine heat-conducting pipes. A preheating box is fixedly installed between the two heat-conducting plates. An exhaust pipe is fixedly installed on the end of each of the two serpentine heat-conducting pipes away from the air inlet pipe.

[0007] Preferably, the suction hood is located on one side of the furnace door, and two mounting rods are fixedly welded to the suction hood. A mounting base is fixedly welded to the end of the mounting rod away from the suction hood, and the mounting base is fixedly installed on the side wall of the annealing furnace body.

[0008] Preferably, an air distribution plate is fixedly welded onto the air suction hood, and the air distribution plate has a plurality of evenly distributed air inlet holes.

[0009] Preferably, the air suction hood, the first air guide pipe, the second air guide pipe, the diversion pipe, and the air inlet pipe are all made of heat-insulating material.

[0010] Preferably, the insulated box is equipped with an insulated box door.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During use, when changing materials after opening the furnace door of the annealing furnace, the exhaust pump can be started. The exhaust pump creates negative pressure in the suction hood through the first air guide pipe, drawing in the hot air emitted by the annealing furnace. The hot air is then discharged into the distribution pipe through the second air guide pipe. The distribution pipe delivers the hot air to two serpentine heat-conducting pipes through two air inlets. The two heat-conducting plates absorb the heat from the serpentine heat-conducting pipes and transfer the heat to the preheating box, thereby preheating the materials. This reduces the preheating time required for materials during annealing and ensures full utilization of the heat emitted by the annealing furnace when changing materials, avoiding waste of heat.

[0018] Please see Figure 1-3This utility model provides a technical solution: an annealing furnace for decarburizing silicon-chromium alloys, comprising:

[0019] An annealing furnace body 1 is provided, with a furnace door 2 installed on the furnace body 1. An air pump 3 is fixedly installed on one side of the furnace body 1, with a first air guide pipe 4 fixedly installed on the air pump 3. A suction hood 5 is fixedly installed at the end of the first air guide pipe 4 away from the air pump 3. A second air guide pipe 6 is fixedly installed on the air pump 3, with a diverter pipe 7 fixedly welded to the end of the second air guide pipe 6 away from the air pump 3. Two air inlet pipes 8 are fixedly welded to the diverter pipe 7. A heat preservation box 9 is installed on one side wall of the furnace body 1. Two serpentine heat conduction pipes 10 are fixedly installed inside the heat preservation box 9. One end of each of the two serpentine heat conduction pipes 10 is fixedly connected to the two air inlet pipes 8. A heat conduction plate 11 is fixedly welded to the opposite side of each of the two serpentine heat conduction pipes 10. A preheating box 12 is fixedly installed between the two heat conduction plates 11. An exhaust pipe 13 is fixedly installed at the end of each of the two serpentine heat conduction pipes 10 away from the air inlet pipe 8.

[0020] The suction hood 5 is located on one side of the furnace door 2. Two mounting rods 14 are fixedly welded to the suction hood 5. A mounting base 15 is fixedly welded to the end of the mounting rod 14 away from the suction hood 5. The mounting base 15 is fixedly installed on the side wall of the annealing furnace body 1. The suction hood 5 is located on one side of the furnace door 2, which makes it easy to draw in the hot air after the furnace door 2 is opened.

[0021] A uniform air distribution plate 16 is fixedly welded onto the suction hood 5. The uniform air distribution plate 16 has several evenly distributed air inlet holes 17. The uniform air distribution plate 16 facilitates expanding the suction range of the suction hood 5.

[0022] The suction hood 5, the first air guide duct 4, the second air guide duct 6, the diversion duct 7, and the air inlet duct 8 are all made of heat-insulating materials to reduce heat loss of hot air during transportation.

[0023] The insulated box 9 is equipped with an insulated box door 18.

[0024] Working principle: During use, when the furnace door 2 of the annealing furnace is opened for material replacement, the suction pump 3 can be started. The suction pump 3 generates negative pressure through the first air guide pipe 4 to draw in the hot air emitted by the annealing furnace through the suction hood 5. The hot air is then discharged into the diversion pipe 7 through the second air guide pipe 6. The diversion pipe 7 delivers the hot air to the two serpentine heat conduction pipes 10 through the two air inlet pipes 8. The two heat conduction plates 11 absorb the heat from the serpentine heat conduction pipes 10 and conduct the heat to the preheating box 12, thereby preheating the material. This reduces the preheating time required for the material during annealing and makes full use of the heat emitted by the annealing furnace when changing materials, avoiding the waste of heat.
