ABSTRACT:
A continuous casting method of a reduced height with a horizontal or almost horizontal oscillating crystallizer, whereby an immersed teeming nozzle teems molten metal into the crystallizer below the meniscus, regulation of the flow being obtained with regulation means corresponding to the formula: V.gtoreq.K.multidot..sqroot.2gh-2p/.rho., a pressure being kept within a tube portion of the teeming nozzle at least transiently which is correlated with the pressure surrounding the teeming nozzle itself and with the pressure acting on the meniscus of the molten metal in the crystallizer, the pressure within the tube portion of the teeming nozzle being such as will at least hinder the migration of gas from the exterior of the nozzle to the inside of the bore of the tube portion.
