Abstract

Molten metal is introduced into a tubular mold and is withdrawn from the mold in the partly solidified state. There is included a sensor to measure the behavior of the metal strand as close as possible to the mold in order to control or regulate the drive unit for the withdrawal of the strand on a continuous casting machine. For a more precise determination of the actual conditions, the movement of the strand is measured in an area close as possible to the point where the strand leaves the mold. The measurement of the movement may be made in a non-contact and non-delayed manner by the sensor which responds to radiation. The sensor is designed and positioned so that it produces an evaluatable measurement signal in response to the displacement-time behavior of the strand. The measurement signal is transmitted to a display unit and/or evaluation unit for adjustment of the drive unit in order to obtain the desired speed of withdrawal.
