Abstract:
A plate mold for producing a steel billet, comprising:opposed broad side walls;water-cooled narrow side walls arranged between the broad side walls so that a mold mouth is formed, the broad side walls being divided into at least three adjacent and mutually independent cooling segment chambers, the broad side walls being divided symmetrically relative to a central axis of the mold, and having, in a region of the mold mouth, separate connections for independent supply of a liquid cooling medium;actuator means for adjusting a hollow space formed by the narrow side walls and the broad side walls to different billet sizes as well as to adjust casting taper;means for oscillating the mold;first temperature sensor means provided in one of the walls of the chambers facing the billet for detecting at least a temperature difference between the individual chambers;second temperature sensing means for sensing temperature at the connection for liquid cooling medium; andcontrol means, connected to the first temperature sensor means, the second temperature sensor means and the actuator means, for controlling the taper of the narrow side walls via the actuator means and balancing specific heat flows per chamber relative to each other by changing oscillation parameters of the mold.
