Abstract: A machine for continuous casting by drawing-up comprises at least two moulds positioned above a metal supply means, and, sequentially arranged in the drawing-up direction of the continuously cast product, a drawing-up means for pulling out said product from said moulds, a cutting-off means for cutting the continuously cast product to lengths, said means being secured directly on the cast product and performing the cutting-off operation during its stepwise upward movement together with the cast product, and a manipulator adapted to place the cut-off lengths onto a conveyer.

Abstract: A process for continuous casting of hollow ingots wherein the rate of heat removal from the surface of an ingot within a mold is changed gradually over the mold height from a given maximum value in the ingot skin formation zone to a given minimum value as the ingot emerges from the mold. The speed of the continuous ingot withdrawal from the mold is increased gradually during each withdrawing cycle from zero to the maximum value for apredetermined length of time. An apparatus in accordance which comprises a water-cooled mold which is made in the form of an inverted truncated cone with the diameter of any of its bases being substantially less than its height. A part of the upper portion of the mold being cylinder-shaped and formed with a plurality of slots. The diameter of projections formed by the slots is slightly less than that of the top base of the frustoconical section, with the walls of the slots passing smoothly into projections.
