Description

Technical Field

[0001] This invention relates to the field of industrial frequency furnace technology, and more specifically, to an industrial frequency furnace with a temperature control device and a temperature control method thereof. Background Technology

[0002] An industrial frequency induction furnace is an induction furnace that uses industrial frequency current as its power source. It has developed into a widely used smelting equipment. It is mainly used as a melting furnace to smelt gray cast iron, malleable cast iron, ductile cast iron, and alloy cast iron. In addition, it is also used as a holding furnace. As before, the industrial frequency induction furnace has replaced the quenching furnace as the main equipment in casting production.

[0003] During operation, the internal temperature of existing industrial frequency furnaces is generally kept at a stable value. During the smelting process, the working temperature of the industrial frequency furnace cannot be adjusted according to the progress of metal smelting. Therefore, maintaining a high temperature and high efficiency smelting state will result in energy waste, while maintaining a low temperature smelting state will result in low smelting efficiency.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an industrial frequency furnace with a temperature control device and a temperature control method thereof.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an industrial frequency furnace with a temperature regulating device, comprising a furnace body, two vertically arranged support rods on both sides of the furnace body, a horizontal sliding rod between the two support rods, the sliding rod being slidably connected between the two support rods in a vertical direction, and a first driving member for driving the sliding rod, a feeding hopper being arranged between the sliding rod and the furnace body, the bottom of the feeding hopper being open, and a weighing member for measuring the weight of the feeding hopper.

[0007] By adopting the above technical solution, during the production and processing of this industrial frequency furnace, metal parts are placed in the feeding hopper, and the first driving component drives the feeding hopper to descend and enter the furnace body. The heating device inside the furnace works to melt the metal parts. After the metal parts melt and fall from the feeding hopper to the bottom of the furnace body, the weighing component detects that the weight of the feeding hopper has become lighter, and the heating device gradually lowers the temperature, ensuring effective melting of the metal parts while improving energy utilization.

[0008] The invention is further configured such that: pull rods are provided on both sides of the top of the hopper; the sliding rod has a first through hole for the pull rods to pass through; a connecting rod is fixedly connected between the ends of the two pull rods that pass through the upper surface of the sliding rod; the weighing component is specifically a pressure sensor disposed on the surface of the sliding rod; and the connecting rod is placed on the surface of the pressure sensor.

[0009] The invention is further configured such that: the sliding rod is fixedly connected to a cover, and the cover has a second through groove for the pull rod to pass through.

[0010] The invention is further configured such that: the opposite sidewalls of the two support rods are provided with a first sliding groove along their height direction, the sliding rod is slidably connected in the first sliding groove, the first driving member includes a first threaded rod rotatably connected in the first sliding groove, the first threaded rod passes through and is threadedly connected to the sliding rod, and the top of the support rod is also provided with a first motor for driving the first threaded rod.

[0011] The present invention is further configured such that: horizontally arranged guide rods are provided on both sides of the furnace body, the support rod is slidably connected to the guide rods, and a second driving component for driving the support rod is also included.

[0012] The present invention is further configured such that: a second sliding groove is formed on the surface of the guide rod along its length direction, the support rod is slidably connected in the second sliding groove, the second driving member includes a second threaded rod rotatably connected in the second sliding groove, the second threaded rod passes through and is threadedly connected to the support rod, and a second motor for driving the support rod is also provided at the end of the guide rod.

[0013] The present invention is further configured such that: a fixing rod is provided on both sides of the furnace body, and a rotating shaft is provided on both sides of the furnace body and rotatably connected to the fixing rod; and an adjustment component for adjusting the angle of the industrial frequency furnace is also included.

[0014] The present invention is further configured such that: the adjusting assembly includes an adjusting rod fixedly connected to one side wall of the support rod, the adjusting rod is parallel to the guide rod, and a pull rope is provided at one end of the adjusting rod, the other end of the pull rope being connected to the bottom of the side wall of the furnace body.

[0015] The invention is further configured such that: a limiting plate is fixedly connected between the other ends of the two guide rods located on the adjusting rod, and the surface of the limiting plate facing the furnace body is an arc-shaped groove that fits into the bottom of the side wall of the furnace body.

[0016] A method for temperature control of an industrial frequency furnace includes the following steps:

[0017] S1. Discharging: The metal parts to be melted are placed in the hopper, and the hopper is driven into the furnace body by the first drive component.

[0018] S2, Smelting: Turn on the furnace to raise the temperature and control the internal air volume at the highest temperature required for smelting;

[0019] S3.

When the weight of the hopper reaches its own weight, the temperature inside the furnace reaches the minimum temperature required for melting.

[0020] The present invention has the following beneficial effects: During production and processing, the metal parts are placed in the feeding hopper, and the first driving component drives the feeding hopper to descend and enter the furnace body. The heating device inside the furnace body works to melt the metal parts. After the metal parts melt and fall from the feeding hopper to the bottom of the furnace body, the weighing component detects that the weight of the feeding hopper has become lighter, and the heating device gradually lowers the temperature, ensuring effective melting of the metal parts while improving energy utilization.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0027] As shown in the figure, an industrial frequency furnace with a temperature control device includes a furnace body 1, a heating device inside the furnace body 1, specifically a heating element composed of an induction coil, two vertically arranged support rods 2 on both sides of the furnace body 1, a horizontal sliding rod 3 between the two support rods 2, the sliding rod 3 being slidably connected between the two support rods 2 in the vertical direction, a first driving component for driving the sliding rod 3 to rise and fall, a feeding hopper 4 between the sliding rod 3 and the furnace body 1, the bottom of the feeding hopper 4 being open and equipped with a drain net 5, a weighing component 6 for measuring the weight of the feeding hopper 4, and a controller (not shown in the figure), the weighing component 6 and the heating device being electrically connected to the controller.

[0028] During production and processing, the industrial frequency furnace places metal parts into the hopper 4. The first driving component drives the hopper 4 to descend and enter the furnace body 1. The heating device inside the furnace body 1 works to melt the metal parts. After the metal parts melt and fall from the hopper 4 to the bottom of the furnace body 1, the weighing component 6 detects that the weight of the hopper 4 has become lighter. The heating device gradually lowers the temperature to ensure effective melting of the metal parts while improving energy utilization.

[0029] Pull rods 7 are provided on both sides of the top of the hopper 4. The sliding rod 3 has a first through hole for the pull rods 7 to pass through. A connecting rod 8 is fixedly connected between the ends of the two pull rods 7 passing through the upper surface of the sliding rod 3. The weighing component 6 is specifically a pressure sensor set on the surface of the sliding rod 3. The connecting rod 8 is placed on the surface of the pressure sensor. The weight of the hopper 4 can be detected in real time through the pressure sensor.

[0030] The sliding rod 3 is fixedly connected to a cover 9. The cover 9 has a second through slot for the pull rod 7 to pass through. When the first drive unit controls the feeding hopper 4 to fully enter the furnace body 1, the cover 9 covers the top of the furnace body 1, thereby ensuring the normal operation of the smelting work.

[0031] The two support rods 2 have first sliding grooves formed on their opposite sidewalls along their height direction. The sliding rod 3 is slidably connected in the first sliding groove. The first driving component includes a first threaded rod 10 rotatably connected in the first sliding groove. The first threaded rod 10 passes through and is threadedly connected to the sliding rod 3. The top of the support rod 2 is also provided with a first motor 11 for driving the first threaded rod 10. The first motor 11 drives the first threaded rod 10 to rotate, thereby controlling the lifting and lowering of the sliding rod 3 and the hopper 4.

[0032] The furnace body 1 has horizontally arranged guide rods 12 on both sides, and support rods 2 are slidably connected to the guide rods 12. A second driving component is also included to drive the support rods 2. Before smelting, the first driving component drives the sliding rod 3 upward, causing the hopper 4 to completely leave the furnace body 1. At this time, the second driving component controls the two support rods 2 to move along the guide rods 12, positioning the hopper 4 on one side of the furnace body 1. The first component then controls the sliding rod 3 and the hopper rod to descend, so that the metal parts can be placed in the hopper 4 for easy loading.

[0033] The guide rod 12 has a second sliding groove along its length. The support rod 2 is slidably connected to the second sliding groove. The second driving component includes a second threaded rod 13 rotatably connected to the second sliding groove. The second threaded rod 13 passes through and is threadedly connected to the support rod 2. The end of the guide rod 12 is also provided with a second motor 14 for driving the support rod 2. The second motor 14 drives the second threaded rod 13 to control the movement of the two support rods 2 along the guide rod 12.

[0034] The furnace body 1 is also equipped with fixing rods 15 on both sides, and rotating shafts rotatably connected to the fixing rods are provided on both sides of the furnace body 1. It also includes an adjustment component for adjusting the angle of the industrial frequency furnace. After the metal parts are completely melted, the first driving component drives the feeding hopper 4 to rise and leave the furnace body 1. Then, the adjustment component controls the furnace body 1 to tilt to one side so that the molten metal can be poured out of the furnace body 1.

[0035] The adjustment assembly includes an adjustment rod 16 fixedly connected to one side wall of the support rod 2. The adjustment rod 16 is parallel to the guide rod 12, and a pull rope 17 is provided at one end of the adjustment rod 16. The other end of the pull rope 17 is connected to the bottom of the side wall of the furnace body 1. After the metal is completely melted, the first drive unit first controls the feeding hopper 4 to rise and leave the furnace body 1. The second drive unit then controls the two support rods 2 to move along the guide rod 12. Under the action of the pull rope 17, the furnace body 1 is deflected, and the molten metal is poured out of the furnace body 1.

[0036] Two guide rods 12 are fixedly connected to a limiting plate 18 between the other ends of the adjusting rod 16. The surface of the limiting plate 18 facing the furnace body 1 is an arc-shaped groove that fits the bottom of the side wall of the furnace body 1, which has a positioning effect on the feeding hopper 4 and ensures the stability of the feeding hopper 4.

[0037] A temperature control method for the above-mentioned industrial frequency furnace includes the following steps:

[0038] S1. Discharging: Place the metal parts to be melted into the hopper 4, and drive the hopper 4 into the furnace body 1 through the first driving component;

[0039] S2, Smelting: Turn on furnace body 1 to heat up. According to the type of metal parts to be smelted, the controller controls the heating device to control the internal air volume of furnace body 1 at the highest temperature required for smelting.

[0040] S3. Temperature control: As the metal parts in the hopper 4 gradually melt and fall to the bottom of the furnace body 1, the controller controls the temperature of the furnace body 1 to gradually decrease according to the data measured by the weighing device 6. When the weight of the hopper 4 reaches its own weight, the temperature inside the furnace body 1 reaches the minimum temperature required for melting.

[0041] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
