METHOD OF ELECTRON-BEAM MELTING OF PRODUCT FROM HIGH-MELTING METAL OR ALLOY, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC C22B34/00 C22B9/22 

FIELD: metallurgy.

SUBSTANCE: method of electron-beam melting of products from high-melting metals and alloys and device for the method's implementation are proposed. The above method involves arrangement of molten material inside replaceable shape-generating melting pot and installation inside cooled vacuum chamber of cathode assembly, anode and melting pot. The latter is fixed inside anode made in the form of a metal pipe and arranged axisymmetrically inside cathode assembly with system of annular focusing electrodes and thready annular cathode. Melting of material in melting pot or first of the bottom part, and then of the whole material is performed by moving anode or cathode assembly relative to each other along their vertical axis with formation of crystallisation zone of molten product at the pot bottom and by movement of zone of molten material upwards with velocity providing the formation of shrinkage hole in upper part of the product.

EFFECT: obtaining complex products of high strength; increasing the surface area of its carrying section.
