摘要： An edge dam position control method and device in a twin roll strip casting process calculates the reduction ratio and rolling force of rolls to obtain the height of a solidification point, and adjusting the height of an edge dam during casting to correspond to the obtained height of the solidification point. It minimizes the force applied to the edge dam during casting, reduces the degree of wear of the edge dam, and improves the quality of edge portions of both sides of the strip. This new method includes the following steps: calculating the position of a solidification point to a rolling force of twin rolls and diagrammatizing the calculated result; measuring a real rolling force of the twin rolls upon casting by means of a load cell; determining whether the position of the solidification point to the measured rolling force of the twin rolls corresponds to the current height of the edge dam; and moving the edge dam to a position where the height of the edge dam corresponds to the position of the solidification point to the measured rolling force of the rolls.
