Determination of solidification end position of continues cast slab based on force model

Abstract

For a better determination of solidification end position during the process of soft reduction to confirm the reasonable reduction position and reduction area and to get the better slab quality, by analyzing the force behaviour of slab shell during soft reduction process, a force dynamic determination model for the end position of liquid core of slab during soft reduction process has been built. The variation trend of reaction force and total pressure of segment clamping-roller with the changing of position of solidification end can be got by the using of model calculation, and by analyzing this trend, a force feedback-based model has been proposed for checking the end position of liquid core. The veracity of the force feedback-based model has been verified by using nail-shooting approach.
