  • Process for controlling the operation of a vertically guided mold for the casting of a billet
    Patent number: 5931215
    Abstract: The invention relates to a process for operating a guided vertical mold, especially for the continuous casting of a steel billet, which is oscillated by a lifting device. According to the invention, the driving force (F), the lift position (x) and/or the lifting speed (v) of the mold are detected by measurement technology, and a mold lifting movement is preset in a computer model as a target variable. Finally, a difference of the mold lifting movement, representing the measure of frictional force between the billet and the mold, is fed as a control variable to actuators by means of a circuit arrangement.
