A method of continuous casting of an ingot by way of its recurrent upward drawing from a radial cooled mould into which molten metal is forced from a bottom of a supply vessel. Pressure is increased inside the ingot being formed in the period of a pause between its drawing from the mould for a tighter fitting of the ingot skin to the walls of the mould, and, once the ingot skin of a prescribed thickness is solidified, the pressure is reduced in the molten metal enclosed by the skin. Thereafter a hole is made in the upper butt portion of the ingot skin and a neutral gas is fed through the hole until the levels of the molten metal in the mould and in the supply vessel are equalized; then the ingot is drawn from the mould. The newly formed upcast branch of the ingot envelope is reduced with the aid of rolls in the course of drawing to a continuous section of a prescribed shape, the volume of a neutral gas (gas cushion) enclosed by the envelope being ahead of the reducing rolls. The method is good for the production of flat, profiled and multilayer ingots.
