Continuous Casting Machine With a Continuous Casting Die for Casting Liquid Metals, Particularly Steel Materials

Abstract

A continuous casting machine ( 1 ) for steel materials has a continuous casting die ( 6 ) with a casting mold ( 10 ) formed of broad-side plates ( 11 ) and narrow-side plates ( 13 ) and at which piston-cylinder units ( 16 ) are provided as actuators and support bearings. The position of the piston-cylinder units ( 16 ) is measured by field measurement devices ( 21 ), the measurement data are stored in a control ( 23 ) of the continuous casting machine ( 1 ) via fieldbus modules ( 22 ) as BUS signals and, after being processed, are fed back to the actuators as control signals. In order to acquire and process the measurement data locally at the continuous casting die ( 6 ), it is proposed that a respective hydraulic cylinder ( 16 a ) is connected to a valve stand ( 24 ) with a stationary terminal box ( 25 ) for the measurement signal lines and control signal lines ( 28 ) and that the terminal box ( 25 ) is connected to an axis regulator ( 30 ) from which the fieldbus module ( 22 ) supplies the signals to a memory-programmable control ( 31 ).
