Abstract:
A method of and apparatus for controlling the cooling of a continuously cast strand of metal at individual cooling zone sections after departing from a continuous casting mold. According to the invention, during casting there is integrated the speed of the individual strand sections over the travel time and there is simultaneously fixed the time spent by a strand section in the cooling zone to determine by means of a computer the amount of cooling agent applied to the individual strand sections. Such value is compared with reference quantities and there is determined the residual amount of cooling agent which is still to be applied to such strand section. As a function of such residual amount of cooling agent after a time-displacement determined by the computer there is selectively changed the length of the individual cooling zone sections, the total length of the cooling zone, or both the length of the individual cooling zone sections and the total length of the cooling zone, to thus maintain constant the residence time of the individual strand sections in the total cooling zone.
