摘要： In the continuous manufacturing of metal strip from molten alloy, the nozzle from which the melt issues to form the continuous strip by rapid-cooling solidification has an orifice that is discontinuous in the width direction of the strip; i.e., it is a multiple orifice. This enables amorphous and crystalline continuous metal strip to be produced in much greater widths than has hitherto been possible, and the strip thus produced is more uniform in thickness.
