  • Process for automatic control of the startup of a continuous casting apparatus
    Patent number: 4774999
    Abstract: At the latest before response of the measuring mechanism which senses the filling state of the melt tundish the opening rate of the outlet of the tundish is brought to near its standard opening rate and, after obtaining a clear signal from the filling state measuring mechanism or reaching a first predetermined filling height, the withdrawal mechanism is switched on and the withdrawal speed delayed for determination of the opening rate of the outlet. Advantageously the speed of the discharge rollers is measured by a tachometer which transmits a normalized signal which is then multiplied by a signal determined by the standard opening rate. The resultant signal controls the opening rate of the outlet.
