[0026] Specifically: when the device is in use, it can be placed at the bottom of the hanging hook movable support frame, and the two connecting plates 101 are used to support and install the electric hydraulic cylinder 3. The base 1 is connected to the base 2 2 for use, and the steelmaking furnace body 6 is located on the surface of the base 1. The steelmaking furnace body 6 is an electric furnace, and its working principle is to convert electrical energy into thermal energy. It can be energized by connecting an external power supply through a connecting line, and a high temperature is generated by an electric arc between an electrode and the charge to melt the charge. When the steelmaking furnace body 6 is steelmaking, in order to prevent debris from falling into the interior of the steelmaking furnace body 6, it is necessary to protect the top of the steelmaking furnace body 6. By starting the two electric hydraulic cylinders 3 on both sides of the base 1, the operation of the electric hydraulic cylinder 3 can push the two support frames 4 to approach the two sides of the steelmaking furnace body 6. At this time, the two protective plates 505 can gradually approach each other, so that the two protective plates 505 are located at the top of the steelmaking furnace body 6 for protection. The two support frames 4 can support the installation of two protective devices 5. When it is necessary to perform steelmaking When feeding in the furnace body 6, the two protective plates 505 can be moved to one side by controlling the protective device 5, and the feeding assembly 7 can be controlled so that the discharge bin 706 at one end of the feeding assembly 7 is located at the top of the steelmaking furnace body 6. At this time, the feeding device 8 can be started to transport the materials in the feeding bin 703 to the inside of the steelmaking furnace body 6 through the feeding device 8. After steelmaking is completed, the electric hydraulic cylinder 3 on both sides of the steelmaking furnace body 6 can be controlled to drive the two protective plates 505 to separate from the top of the steelmaking furnace body 6, and the auxiliary hanger can be located above the steelmaking furnace body 6 by moving the support frame, and the auxiliary hanger can be hooked on the lifting columns on both sides of the steelmaking furnace body 6. At this time, the steelmaking furnace body 6 can be supported and lifted, and the positioning hook on the hanger is hooked on the connecting rod movably connected to the inner side of the two clamping plates at the bottom rear of the steelmaking furnace body 6. At this time, the connecting rod is driven upward by controlling the positioning hook, so that one end of the steelmaking furnace body 6 is tilted downward, and the refined molten steel can be poured out from the inside of the steelmaking furnace body 6.

[0027] In one embodiment, the protective device 5 includes a forward and reverse motor 501, which is fixedly embedded in the top of one side of the support frame 4, and a threaded rod 502 is fixedly installed on the output end of the forward and reverse motor 501. One end of the threaded rod 502 is connected to one side of the inner wall of the mounting groove 401 through a bearing. A slider 503 is movably sleeved on the surface of the threaded rod 502, and a movable plate 504 is installed on one side of the slider 503. A protective plate 505 is installed on one side of the movable plate 504, and the protective plate 505 is movable on the top of the steelmaking furnace body 6.

[0028] Specifically: when the steelmaking furnace body 6 is performing steelmaking, the two forward and reverse motors 501 can be started through an external controller. The operation of the two forward and reverse motors 501 can drive the threaded rod 502 to rotate forward and reversely. When the two threaded rods 502 rotate forward, the sliders 503 on the surfaces of the two threaded rods 502 can move toward one side of the top of the steelmaking furnace body 6. At this time, the protective plates 505 connected to the two moving plates 504 move along with it. Since the two forward and reverse motors 501 rotate synchronously, the two protective plates 505 can move synchronously with it, so that the two protective plates 505 are located at the top of the steelmaking furnace body 6 for protection, thereby protecting the safety of the staff.

[0029] In one embodiment, the feeding assembly 7 includes two support columns 701, and a lower feeding bin 702 is installed on the top of the opposite sides of the two support columns 701, and a feeding bin 703 is installed on the top of the lower feeding bin 702. A T-shaped slider 704 is installed on the bottom of the two support columns 701, and a feed bin 705 is connected to one side of the lower feeding bin 702, and a discharge bin 706 is installed on one side of the feed bin 705. An electric hydraulic cylinder 2 707 is installed on one side of the two support columns 701, and one end of the two electric hydraulic cylinders 2 707 is connected to the surface of the connecting plate 201.

[0030] Specifically: the materials required for steelmaking can be added to the interior of the charging bin 703, so that the interior of the steelmaking furnace body 6 can be filled at any time. When materials need to be added, the two electric hydraulic cylinders 707 can be started through an external controller. The operation of the two electric hydraulic cylinders 707 can drive the two support columns 701 to move to one side of the steelmaking furnace body 6. At this time, since T-shaped sliders 704 are installed at the bottom of the two support columns 701, the movement of the support columns 701 allows the T-shaped sliders 704 to move inside the T-shaped movable groove 202, which can make the movement of the support columns 701 stable. When the two support columns 701 move, the discharge bin 706 at one end of the feed bin 705 can be located above the steelmaking furnace body 6. Starting the feed device 8 can transport the materials inside the charging bin 703, so that the steelmaking materials are added to the interior of the steelmaking furnace body 6 through the discharge bin 706.

[0031] In one embodiment, the feeding device 8 includes a motor 801, which is fixedly embedded in one side of the lower material bin 702. A connecting rod 802 is fixedly installed on the output end of the motor 801. One end of the connecting rod 802 is connected to one side of the inner wall of the discharge bin 706 through a bearing. A auger piece 803 is wrapped around the surface of the connecting rod 802.

[0032] Specifically: the motor 801 can be started by an external controller, and the operation of the motor 801 can drive the auger piece 803 on the surface of the connecting rod 802 to rotate. At this time, the steelmaking material located inside the charging bin 703 can be rotated and pushed by the auger piece 803, so that the steelmaking material is transported to the inside of the discharge bin 706 through the auger piece 803, and is added to the inside of the steelmaking furnace body 6 through the discharge bin 706.

[0033] In one embodiment, the four T-shaped movable plates 403 are evenly divided into two groups, and the two groups of T-shaped movable plates 403 are movable inside the two T-shaped movable grooves 102 .

[0034] Specifically: after the steelmaking is completed, the two electric hydraulic cylinders 3 on both sides of the base 1 can be started so that the electric hydraulic cylinders 3 can drive the support frame 4 to move to one side. At this time, the two T-shaped movable plates 403 at the bottom of the support frame 4 can move inside the T-shaped movable groove 102, and the moving position of the support frame 4 can be limited, so that the movement of the support frame 4 is stable.

[0035] In one embodiment, the two T-shaped sliding blocks 704 are movable inside the two T-shaped movable grooves 202, and the interiors of the lower material bin 702, the loading material bin 703, the feeding material bin 705, and the discharging material bin 706 are interconnected.

[0036] Specifically: after the steelmaking materials are added into the interior of the feeding bin 703, they can fall into the interior of the lower bin 702, and be pushed and transported through the feeding device 8 inside the feeding bin 705, so that the steelmaking materials are finally discharged into the interior of the steelmaking furnace body 6 through the discharging bin 706. When the two support columns 701 are moved, the T-shaped sliders 704 at the bottom ends of the two support columns 701 can move inside the two T-shaped movable grooves 202, which can increase the stability of the movement of the support columns 701.

[0037] Working principle: When the steelmaking furnace body 6 is in the process of steelmaking, the two electric hydraulic cylinders 3 on both sides of the base 1 can be started by an external controller, so that the electric hydraulic cylinders 3 on both sides can drive the two support frames 4 to approach the two sides of the steelmaking furnace body 6. At this time, the two protective plates 505 can be abutted against each other, and the top of the steelmaking furnace body 6 can be covered and protected. The two forward and reverse motors 501 are started by the external controller, and the two forward and reverse motors 501 operate and drive the slider 503 on the surface of the threaded rod 502 to move, so that the two moving plates 504 drive the two protective plates 505 to move to the appropriate position on the top of the steelmaking furnace body 6, thereby moving and adjusting the position of the two protective plates 505. By setting the protective device 5, the steelmaking furnace body 6 can be protected during the steelmaking process, and debris can be prevented from falling into the interior of the steelmaking furnace body 6 so that the molten steel splashes and causes harm to the staff, which has a certain degree of safety. When it is necessary to add steelmaking materials to the interior of the steelmaking furnace body 6, the staff can add the steelmaking materials to the interior of the charging bin 703 in advance, and the two forward and reverse motors can be controlled by the external controller. 501 drives the two threaded rods 502 to rotate in the opposite direction, so that the two protection plates 505 move synchronously to one side of the top of the steelmaking furnace body 6, and start the two electric hydraulic cylinders 707. The operation of the two electric hydraulic cylinders 707 can drive the two support columns 701 to move to one side of the connecting plate 201. At this time, the discharge bin 706 can be located just at the top of the steelmaking furnace body 6 for charging. The motor 801 is started. The operation of the motor 801 can drive the auger piece 803 on the surface of the connecting rod 802 to rotate, and the auger piece 803 located inside the charging bin 703 is rotated. The steelmaking materials can be rotated and transported by the auger piece 803. At this time, the auger piece 803 can rotate and push the steelmaking materials to the inside of the discharge bin 706, and make the steelmaking materials fall downward into the inside of the steelmaking furnace body 6 through the discharge bin 706. After the feeding is completed, the two support columns 701 are moved to their original positions by controlling the two electric hydraulic cylinders 707. By setting the feeding component 7, the steelmaking furnace body 6 can be fed during the steelmaking process, and the feeding device 8 is set to be able to quantitatively feed the steelmaking furnace body 6, which can improve the efficiency of steelmaking production.
