METHOD AND DEVICE FOR REGULATING THE HEIGHT OF THE CASTING LEVEL IN CONTINUOUS CASTING SHELLS

摘要

P THE PROCESS OPERATED BY DETECTING THE VARIATIONS IN THE CASTING LEVEL ACCORDING TO THE PRINCIPLE OF CURRENT FOUCAULT, A HIGH-FREQUENCY ALTERNATIVE MAGNETIC FIELD INDUCING, IN TWO SECONDARY RECEPTOR COILS, VOLTAGES WHOSE THE DIFFERENTIAL VOLTAGE RESULTING IS MADE EQUAL TO ZERO FOR THE ASSIGNED HEIGHT AT THE LIQUID LEVEL, AND THE VOLTAGE CREATED WHEN THE CASTING LEVEL EXCEEDS THE ASSIGNED HEIGHT BEING USED FOR REGULATION. / P P THE DEVICE HAS TWO SECONDARY RECEIVER COILS 3 AND 4, MOUNTED INTO OPPOSITION, ASSISTANT TO A PRIMARY COIL 2 CONNECTED TO A HIGH FREQUENCY TRANSMITTER 1, AND A COMPENSATION COIL 5 AND A COIL 6 CONNECTED TO THE PROBE 7 WHICH ARE DETECTIONABLE, WHICH ARE RESPECTIVELY CONNECTED TO THE RECEPTORS COIL. / P P YOU CAN USE THIS PROCESS FOR CASTING BARS OF COPPER AND BRASS. / P
