Verfahren und Anordnung zur Herstellung eines Rohres

摘要

#CMT# #/CMT# The tube production process involves drawing the tube from a melt in a crucible (16), the temperature of the melt being is set in individual regions of it independently of each other by regulation in a tube drawing device (10) supplied with materials kept molten by heaters, so that the melt passes through a capillary gap and rises to a meniscus high enough to pass over a seed crystal. #CMT#USE : #/CMT# For tubes, by edge-defined film-fed growth. #CMT#ADVANTAGE : #/CMT# More uniform wall thickness. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing illustrates the principle of a device for drawing a tube from a melt. 10 : Tube drawing device 14 : Floor insulation 18 : Input device 30 : Aperture.
