The technologies and equipment have been developed for electron-beam scull melting with electromagnetic stirring of melt for some Ni-based superalloys as well as for multi-component Ti-, Zr-, Nb-, and Mo-based alloys. Two types of scull crucible sets with electromagnetic stirring systems have been constructed, with the metal pouring by the crucible tilting or through the hole in the crucible bottom. In the second case slag does not fall into a mold, and the electron beam may be used for metal heating in the costing head, thus improving the quality of castings. The technologies developed allow to utilize scrap, cost part reverts, chips etc. thus saving virgin alloys. The electromagnetic stirring application permits to product multi-component alloys, to increase the mass of the metal poured, and to reduce the specific energy expenditure and metal loss through evaporation.
