Description

Technical Field

[0001] The utility model relates to the technical field of nickel-based alloy smelting, in particular to a nickel-based alloy induction smelting feeding device. Background Art

[0002] Nickel-based alloy is a kind of alloy material with nickel as the main component. It has the characteristics of high strength, corrosion resistance, high temperature resistance, oxidation resistance and wear resistance at high temperature of 650-1000℃. Therefore, it is widely used in aerospace, chemical, petroleum, energy, shipbuilding and other fields, nuclear industry and other fields. Nickel-based alloy is usually produced by induction furnace smelting. In its production process, corresponding feeding device is needed to add the corresponding raw materials into the induction furnace for smelting processing.

[0003] After searching, the existing patent (Announcement No.: CN217968516U) discloses a nickel-based alloy induction melting feeding device, which is applied to the field of nickel-based alloy processing technology, including a main body, the interior of the main body is respectively connected to a first pressure roller and a second pressure roller by bearings, and one end of the first pressure roller and the second pressure roller is respectively welded with a plurality of first gear teeth and a second gear teeth, a connecting plate is welded on an outer side wall of the main body, and a motor is welded on one side wall of the connecting plate. When the material needs to be melted and processed, the motor is first started, and the motor drives the second pressure roller to rotate. Because the second gear teeth are meshed with the first gear teeth, the second gear teeth will also drive the first pressure roller to rotate. At this time, the first pressure roller and the second pressure roller will rotate in opposite directions, and then the material is placed in the main body. The material will be squeezed by the first pressure roller and the second pressure roller, causing the material to deform, and then the heating area of ​​the material is increased, which is convenient for the subsequent further operation of the material, reducing the time for the material to melt, thereby increasing work efficiency.

[0004] However, in the above scheme, it is inconvenient to adjust the height of the discharge port. The existing method is to install and fix the feeding device on the top of the induction furnace, and connect the feeding port of the feeding device with the feeding port of the induction furnace. However, the feeding ports of different induction furnaces have different heights, and the height of the feeding port of the feeding device is mostly fixed. Therefore, it is often necessary to repeatedly adjust the installation height position between the feeding device and the induction furnace to ensure the accurate connection between the discharge port and the feeding port. Some of them require a pad to raise the height or add an additional connecting pipe, which leads to inconvenience in its smelting processing.

[0005] In view of this, the utility model provides a nickel-based alloy induction melting feeding device. Utility Model Content

At this time, the fixed plate 8 is used to centrally guide the added material, and then the servo motor 7 is started to drive the pressure roller 10 to rotate, and the material is squeezed and deformed, so that the material has a larger heating area, and then guided by the guide plate 9, so that it is discharged into the induction furnace through the inner discharge pipe 402 and the outer discharge pipe 401, so that the induction furnace can better melt the material;

[0040] At the same time, the relative rotation between the scraper 602 and the pressure roller 10 can be used to scrape off the material adhered to the surface of the pressure roller 10, thereby improving the material utilization rate.
