<p>Casting method and immersed teeming nozzle for a continuous casting machine of a reduced height with a horizontal or almost horizontal oscillatory crystallizer (16), whereby an immersed teeming nozzle (11) teems molten metal into the crystallizer (16) below the meniscus, regulation of the flow being obtained with regulation means (14), a pressure being kept within a tube portion (15) of the teeming nozzle (11) at least transiently which is correlated with the pressure surrounding the teeming nozzle (11) itself and with the pressure acting on the meniscus (17) of the molten metal in the crystallizer (16), the pressure within the tube portion (15) of the teeming nozzle (11) being such as will at least hinder the migration of gas from the exterior of the nozzle (11) to the inside of the bore of the tube portion (15).</p> |
