Abstract

945,992. Electron beam apparatus. W. C. HERAEUS G.m.b.H. April 25, 1960 [April 24, 1959], No. 14409/60. Heading H1D. In an electron beam casting furnace one or more electron beams are produced in separately evacuable chambers 13 and diverted on to the lower end of the consumable electrode 6. The beams are preferably also directed on to the molten pool 8. Each electron beam chamber 13 includes a cathode 14, a focusing electrode 15, magnetic deflection coils 17 and an apertured shield 16. An inert gas, e.g. helium or argon, may be fed into the furnace chamber at 20 and the suction sleeve 2 includes a throttle valve 21. The base 11 of the crucible 10 may be lowered during the melting operation in order to maintain the molten pool 8 always at the same level. Both the crucible 10 and the base 11 are water-cooled. The consumable electrode 6 may be automatically advanced so that the lower end of the electrode is always situated in the zone of overlapping electron beams. The electrode holder 5 is introduced through a seal 4 which may be a sliding seal or may contain pressure reduction stages. Where several electron beams are used, one or more beams may be directed on to the consumable electrode and one or more beams on to the molten pool.
