METHOD AND DEVICE FOR DETERMINING THE CORE SOLIDIFICATION AND/OR THE LIQUID CRATER TIP DURING THE CONTINUOUS CASTING OF METALS, IN PARTICULAR STEEL MATERIALS

摘要

A method and a device for determining the core solidification (1) and/or the liquid crater tip (2) during the continuous casting of liquid metals, in particular liquid steel materials, in a continuous casting machine (1b) does not cause the top frame (5) with the top rollers (4) to oscillate, but rather the driven top roller (11a) rotatably mounted on a crosspiece (11) and opposite a bottom roller (8), the measured values of said top roller (11a) being used, via a computer program (12), at least for the feedback control of the actuating force of the top frame (5) via a control program (13) and/or the cooling (14) or the actuators for further casting parameters.
