A METHOD OF CONTROLLING THE COOLING PERFORMANCE OF THE END WALLS OF PLATE MOULDS DURING CONTINUOUS CASTING AND APPARATUS FOR PERFORMING THE SAME

摘要

A method of controlling the cooling rate of narrow side walls of plate molds during continuous casting, wherein the narrow side walls are fixedly clamped between the wide side walls, prior to start of the casting the hollow casting compartment between the narrow side walls is provided with a casting taper which converges in the direction of travel of the cast strand or casting and which is accommodated to the quality of the steel and the width of the strand. Prior to the start of the casting operation the casting taper is additionally adjusted to a reference value which corresponds to the contemplated casting speed and/or casting temperature, and upon deviation of the casting speed and/or casting temperature during the casting operation the casting taper is changed in accordance with reference values corresponding to such fluctuating or changing casting parameters.
