Abstract: The method allows the continuous, very regular production of glass-coated metal wire on the basis of the TAYLOR-ULITOVSKY principle. The feeding of the molten bath (12) by the guide tube (45) is made by means of a regulated dispensing system (40) allowing the very regular, precise adding of metal particles at a rate corresponding to the rate of wire drawing without disturbing the molten metal bath (14). The system is advantageously completed with a vacuum system (38), a pyrometer (30), a magnet (47), an automatic travel system (25) for the glass tube (20), a spooling system (11) and a water spray (34). Application to the manufacture of metal wire and in particular to glass-coated ferromagnetic wire.

Abstract: The device and process allow for continuous processing of metal wire sheathed in glass (10) of considerable length. Normally a feed pipe (15) containing all the necessary metal, itself placed into a glass tube (20), so as to continuously supply a bead (14) to the lower part of the glass tube (20). Heat from a first inductor (23) around the glass tube (20) and a second inductor (24) under the glass tube (20) allow to maintain a bead (14) at a stable temperature and in a continuous manner and to obtain the continuous drawing process of a metal wire sheathed in glass (10).
