Problems solved by technology
At present, in the process of high-purity smelting of high-temperature alloys, the crucible is prone to loss after repeated use and produces oxide inclusions in the melt, polluting the alloy melt, and needs to be replaced frequently; at the same time, based on production efficiency and working conditions Considering that it is required to change the crucible and alloy masterbatch without breaking the vacuum condition
[0003] However, at present, the crucible or alloy masterbatch is usually replaced by breaking the vacuum or shutting down the equipment, which greatly reduces the production efficiency and leads to difficulties in equipment maintenance; Calcium crucible, etc.) usually have the characteristics of hard and brittle, and it is easy to prevent bumping during the replacement process of the crucible or masterbatch, which will cause the crucible to be damaged, or friction between the crucible and the masterbatch will cause inclusions to be introduced into the alloy melt

Embodiment 1
[0025] A process for automatically changing a crucible for a vacuum induction melting furnace, the specific operations are as follows:
[0026] Step 1: Carry out vacuum-breaking treatment on the automatic replacement crucible and alloy masterbatch device system, place a new crucible on the feeder 1 of the push device, close it for vacuuming, and open the plug valve 16 at this time to communicate with the melting furnace chamber to ensure melting The coil is in a horizontal position, and the crucible is delivered to the outer end of the melting coil by 20 mm through the control system to run the linear module 8, and the crucible is slowly transported to the bottom of the inner crucible by about 5 mm
[0027] Step 2: Run the pneumatic tongs to withstand the outer wall edge of the outer crucible, and run the discharge pinch 1 slowly. After the pinch 1 runs out of the crucible, quickly run the pinch and the pneumatic clamp to the sealed chamber 17. Rotate the induction smelting co...

The invention belongs to the technical field of vacuum induction smelting, and provides a device for automatically replacing a crucible and alloy masterbatch for a vacuum induction melting furnace. The device comprises a crucible body, a bracket, a pushing device, an inserting plate valve and a sealing chamber; the sealing chamber is formed in the front end of a smelting furnace door for replacingthe masterbatch and the crucible body, and the inserting plate valve is arranged at the communication position between the sealing chamber and the smelting furnace for isolating and communicating thesmelting furnace and the sealing chamber to reduce the influence on vacuum environment in the smelting furnace; and stable replacement of the crucible body and the alloy masterbatch under vacuum condition is realized by utilizing a material pinch and a pneumatic clamp of the pushing device, friction and collision between the crucible body and the alloy masterbatch and the crucible body are avoided, the production efficiency is improved, the simple and convenient maintenance of the device is ensured, and the efficient and stable high-purity smelting of high-temperature alloy is realized.
Description
technical field [0001] The invention belongs to the technical field of vacuum induction smelting, and relates to an automatic replacement crucible and alloy masterbatch device for a vacuum induction smelting furnace. Background technique [0002] High-temperature alloy smelting is based on the requirements of high purity, high efficiency and stable production. In order to prevent the contamination of the interface reaction between the alloy melt and the crucible, it is necessary to replace the melting crucible under vacuum conditions, and it is necessary to ensure continuous feeding under vacuum conditions. At present, in the process of high-purity smelting of high-temperature alloys, the crucible is prone to loss after repeated use and produces oxide inclusions in the melt, polluting the alloy melt, and needs to be replaced frequently; at the same time, based on production efficiency and working conditions Considering that it is required to replace the crucible and alloy ma...
