The paper illustrates the use of a heat balance in the design of small furnaces , and then discusses the principles of arc , arc -image, induction, electron-bombardment, resistor-heated and gas-fired ...
, transferred arc plasma furnace (TAP) can meet all requirements, but the disadvantage of this technology is the high cost. For performing experiments in the laboratory , the TAP was fabricated indigenously ...
in laboratory plasma- arc furnace in a graphite crucible at an arc power of 16–40 kW. The microstructure and X-ray phase analysis of the solidified melt were investigated after arc melting . The melt separated ...
Abstract The electromagnetic processes in the laboratory of three-phase arc furnaces is simulated with allowance for the spatial energy release in electrodes and a charge. Main laws are established ...
THE Metropolitan-Vickers Electrical Co., Ltd., has developed small induction furnace equipments which are particularly suited for laboratory work. They were originally designed for the Company's own ...
. The zirconium sponge is pressed into briquets and melted in graphite crucibles in a new graphite resistor vacuum furnace capable of melting over 10 pounds of zirconium a charge. LARGE-SCALE LABORATORY PRODUCTION ...
atmospheric pressure by a 9–16 kW arc discharge of direct polarity in a laboratory furnace . There are the two variants of melting : by a diffuse arc with a distributed heating spot and by a contracted arc ...
