Abstract

Centrifuge for producing fibres from thermoplastic materials, in particular from glass, having a peripheral wall which is provided with rows of outlet passages arranged above one another and is connected, at its lower edge, to a flange which protrudes into the interior of the centrifuge, which centrifuge can be set in rotation about a vertical axis within an annular drawing-gas stream and consists of an alloy with the following composition ("constituent: content in % by weight"): C: 0.65 - 0.83; Cr: 27.5 - 31; W: 6 - 7.8; Fe: 7 - 10; Si: 0.7 - 1.2; Mn: 0.6 - 0.9; Co: 0 - 0.2; P: 0 - 0.03; S: 0 - 0.02; Ni (remainder): 59 - 50; making it possible to produce in particular hard glass fibres with a viscosity of the order of 1000 P at a temperature of over 1150 degrees C and a devitrification temperature of the order of magnitude of 1030 degrees C.
