Abstract
Systems for melt supply to the cooling disk in the production of amorphous and microcrystalline ribbon are considered. For large-scale industrial production, the optimal technology includes lateral supply and inductive melting of the initial blank (regardless of the melt volume). The design of the casting nozzle must be free of danger spots; the material employed will depend on the composition of the melt being cast. For an ampoule system, remote visualization of the nozzle-disk gap is recommended, as well as remote control of the crucible motion. The use of a composite cooling disk reduces wobble at its working surface and simplifies the design. The influence of vibration on ribbon quality must be taken into account in selecting the drive and bearings. The device for removing the ribbon from the disk surface must provide auxiliary ribbon cooling.
