A METHOD OF AND AN APPARATUS FOR PRODUCING FIBRES BY INTERNAL CENTRIFUGATION AND THE APPLICATION OF THE SAID METHOD AND APPARATUS TO THE DRAWING OUT OF CERTAIN GLASSES INTO FIBRES |
摘要 |
Techniques for making fibres by internal centrifuging of glasses of high melting point, such as basaltic glasses. …<??>According to the invention the fibre production is obtained by maintaining a temperature gradient between the inner and outer walls of the peripheral band of the centrifuge. The invention also relates to a device for making fibres in which the peripheral band is made of a material which has a thermal conductivity lower than 20 W m<-1> DEG C<-1> at 1000 DEG C. …<??>Application to the production of fibres from glasses whose working range is less than 100 DEG C in width. …<IMAGE>… |
