Abstract
PURPOSE: To grasp the leading end position of the unsolidified part of an ingot more accurately by measuring at least the first force out of the forces in the ingot pulling, thickness and width directions to be exerted from the ingot upon its holding rolls.
CONSTITUTION: When the leading end (p) of the unsolidified part M under drawing of an ingot is at the intermediate of rolls Rn and Rn+1, the force in the drawing (x) direction acts more largely than the bulging (y direction) force of the ingot upon the rolls on the upper stream side thereof. The force in the (x) direction acts just slightly upon Rn+1 and the rollers on the lower stream side thereof. Hence, if the reactions in the (x) direction of 2 to a number of rolls near the (p) estimated position are measured with load cells in the steady work, the position (p) is clearly identified. With the conventional measurement of only the (y) direction, the difference in the roll reaction of Rn, Rn-1 does not markedly appear when (p) is right under the roll Rn. The measured values of the roll reactions with the change in the position (p) are always larger in the (x) direction than the (y) direction, and the change is larger in the ratio x/y of the measured values, thus the accuracy is higher with the decision of the position (p) in the (x) direction or ratio x/y. Further, if the measurement of the forces in the width (z) direction of the ingot is added, the deviation of (p) in the (z) direction is detected as well.
