[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] This utility model provides a melting furnace for automobile casting production, including a furnace body 1, which is a hollow, open-top structure. A cover plate 2 is installed on the top of the furnace body 1. Heating resistors 101 are evenly distributed on the inner wall of the furnace body 1. A power supply 103 is installed on the outer wall of the furnace body 1 via a rectangular plate 102. The power supply 103 is connected to the heating resistors 101 via cables 104. A heat insulation layer 105 is installed outside the heating resistors 101 in the furnace body 1. A heat insulation block 106 is installed at the bottom of the cover plate 2. A loading furnace 3 is installed inside the furnace body 1. The furnace 3 contains a car-shaped raw material 301 to be melted. The furnace 3 is rotatably installed in the furnace body 1. The bottom of the furnace body 1 is equipped with a support foot 4. The bottom of the furnace 3 is equipped with a connecting block 302. The bottom of the furnace body 1 is equipped with a servo motor 303. The output end 304 of the servo motor 303 is connected to the connecting block 302. The top of the cover plate 2 is equipped with an auxiliary ring 201. A gas pipe 202 passes through the cover plate 2 and is connected to the inside of the furnace body 1. A control valve 203 is installed on the gas pipe 202 to facilitate the opening and closing of the gas pipe 202.

[0020] In actual use, the smelting furnace for automobile casting production places the raw material 301 to be melted into the furnace 3. Then, a cover plate 2 is placed at the open position of the furnace body 1. A heat insulation block 106 is installed at the bottom of the cover plate 2, blocking the hot air generated at the furnace 3 opening. Power is supplied by a power source 103 and cables 104 to multiple heating resistors 101 within the furnace body 1. The heating resistors 101 heat up and transfer heat to the furnace 3. Simultaneously, a servo motor 303, with output 304, drives the furnace 3 above the connecting block 302 to rotate within the furnace body 1, ensuring uniform heating of the entire furnace 3. Spherical protrusions 305 are evenly distributed at the bottom of the furnace 3 to prevent jamming during rotation. A temperature monitor 204 on the cover plate 2 monitors the internal temperature of the furnace body 1 in real time, and the furnace is then operated by personnel. The control valve 203 is activated to release the high-pressure gas inside the furnace body 1, ensuring its normal operation. A rotatable loading furnace 3 is installed inside the furnace body 1, and the raw material 301 to be melted (from a car) is placed in it. A servo motor 303, in conjunction with the output end 304, drives the loading furnace 3 above the connecting block 302 to rotate within the furnace body 1, ensuring uniform heating of the loading furnace 3 and uniform melting of the raw material 301 inside. The gas pipe 202 above the cover plate 2, in conjunction with the control valve 203, promptly releases the high-pressure gas. A temperature monitoring instrument 204 monitors the internal temperature of the furnace body 1 in real time. Compared to conventional fixed furnace structures, this invention achieves uniform heating and melting of the raw material 301, improving melting quality. The overall structure is compact, with a reasonable spatial layout, facilitating installation and maintenance by staff.

[0021] Example 1

[0022] like Figure 1-2 As shown, spherical protrusions 305 are evenly distributed on the bottom of the charging furnace 3, and a temperature monitoring instrument 204 is also installed on the cover plate 2. The temperature monitoring instrument 204 is connected to the interior of the furnace body 1.

[0023] The effect achieved by the entire embodiment 1 is that, during use, the bottom of the loading furnace 3 is evenly distributed with spherical protrusions 305, so that the loading furnace 3 is not easy to get stuck when it rotates in the furnace body 1.

[0024] Working principle: The raw material to be melted is placed in the furnace, and then a cover plate is placed at the open position of the furnace top. A heat insulation block structure is installed at the bottom of the cover plate, which is located at the open position of the furnace to block the hot air generated at the furnace position. Then, the power supply and cables supply power to multiple heating resistors in the furnace. After the heating resistors are energized, they heat up and transfer heat to the furnace position. At the same time, the servo motor, with the output end, drives the furnace above the connecting block to rotate in the furnace, so that the entire furnace is heated evenly. The bottom of the furnace is evenly distributed with spherical protrusions to prevent the furnace from jamming when rotating in the furnace. The temperature monitoring instrument on the cover plate monitors the temperature inside the furnace in real time. Then, the operator operates the control valve to open the control valve to release the high-pressure gas inside the furnace and ensure the normal operation of the furnace.
