Problems solved by technology
[0005] The purpose of the present invention is to provide a vacuum smelting furnace for high-chromium-nickel-based cast superalloys, which mainly solves the problem that after long-term use of the vacuum smelting furnace, impurities will accumulate if the inner wall of the furnace is not wiped, which will affect the purity of smelting. However, during the cleaning process , due to the relatively high furnace wall, its internal temperature is also high, manual cleaning is more difficult and dangerous

Embodiment approach
[0048] As an embodiment of the present invention, a sealing ring 14 is provided on the part of the furnace body 1 penetrated by the lower ring gear 1203 .
[0049] During the use of the vacuum smelting furnace for high-chromium-nickel-based cast superalloys, a sealing ring 14 is provided at the part of the furnace body 1 penetrated by the lower ring gear 1203 to prevent gaps in the part of the furnace body 1 penetrated by the lower ring gear 1203, The vacuum environment inside the furnace body 1 is affected, and the production quality of the superalloy is affected.
[0050] Working principle: When the inner wall of the furnace body 1 needs to be cleaned, the No. 1 motor 1209 is started, and the No. 1 motor 1209 drives the lower inner gear 1203 to rotate, and the lower inner gear 1203 drives the lower gear 1202 to rotate between the lower inner gear 1203 and the lower outer gear. The gears rotate between the rings 1201, and the connecting rod 1205 drives the roller 1208 to rota...

The invention relates to the field of smelting patents, in particular to a vacuum smelting furnace for high-chromium nickel-based cast superalloy. The vacuum smelting furnace comprises a furnace body, wherein a furnace cover is movably connected to the top end of the furnace body, a handle is fixedly connected to the top end of the upper surface of the furnace cover, a vacuum meter and an observation window are arranged on the upper surface of the furnace cover and located at the left end and the right end of the handle correspondingly, a plurality of supporting frames are fixedly connected to the periphery of the lower surface of the furnace body, a first cavity is formed in the furnace body, a base plate is fixedly connected to the middle of the lower surface of the first cavity, a coil is fixedly connected to the upper surface of the base plate, a fixing frame is arranged in the coil, a crucible is slidably connected to the inner surface of the fixing frame, an ash removal unit is arranged on the side surface of the first cavity, and the problems that in the cleaning process, due to the fact that the furnace wall is relatively high, the internal temperature of the furnace wall is high, and manual cleaning is difficult and dangerous are solved through the arrangement of the ash removal unit.
Description
technical field [0001] The invention relates to the field of smelting patents, in particular to a vacuum smelting furnace for high-chromium-nickel-based cast superalloys. Background technique [0002] High-chromium-nickel-based cast superalloys refer to cast superalloys with chromium-nickel as the main component. With the increase of service temperature and strength, the degree of superalloy alloying (see superalloy strengthening) is getting higher and higher, and hot forming is becoming more and more difficult, so it must be produced by casting process. [0003] At present, when high-chromium-nickel-based high-temperature alloys are cast, they are often smelted in a vacuum smelting furnace. The vacuum smelting furnace passes through a coil, and a repeatedly changing current is passed into the coil. Eddy currents are generated in the metal in the furnace, and the heat generated by the eddy currents melts the metal. The advantage of using eddy current metal smelting is that ...
