Title: Automatic mould level control - for continuous casting plant by tundish stopper control with overriding casting speed control
Inventor: BRUDERER WERNER
IPC: B22D11/20
Filed: 1973-10-16
Abstract: An automatic mould level control system for continuous casting installations acts on a stopper control of the tundish nozzle and/or on varying the casting speed to keep the metal in the mould at constant height. A radioactive source emits gamma rays to monitor the level. Correcting signals are applied to the stopper control, and also to a function generator for the casting speed control. The latter is also governed by a casting speed setting unit; its output function is such that the casting speed is altered only when the rate of change of the correcting condition in the stopper control circuit exceeds a certain threshold.
