Abstract
At least one metal strip of small width is manufactured from a molten material held in a metallurgical vessel at a temperature above a melting point of the molten material, by the steps of subjecting the molten material to a pressure at least equal to atmospheric pressure and ejecting the molten material through orifices in a lower part of a nozzle fastened to the vessel and onto a moving cooling surface located beneath the nozzle, the orifices being elongated in the direction of movement of the cooling surface. The molten material is permitted to solidify in grooves in the cooling surface, the grooves being elongated in the direction of movement and facing and being in longitudinal alignment with the orifices.
