METHOD FOR CONTROLLING THE DRAWER OF A CAST POUCH WITH AUTOMATIC COMPENSATION OF ERRORS RESULTING FROM LEAKS ON DEVICES LOCATED IN THE EXTREME ENVIRONMENTAL CONDITION ZONE

摘要

P A CASTING POUCH 13 IS EQUIPPED WITH A DRAWER 11 MANEUVER BY A VERIN 12. THIS VERIN 12 IS HIMSELF MANEUVERED BY A HYDRAULIC INSTALLATION THAT TAKES INTO ACCOUNT: ON THE ONE HAND THE LEVEL 14 OF THE FUSION BATH IN THE LINGOTIERE; On the other hand, the flow velocity from the casting bag. / P p THIS FLOW SPEED DEPENDS ON ITSELF OF A COEFFICIENT OF RESISTANCE, THAT A DETERMINED CALCULATION SET AT ANY TIME AND MEMORIZED, AND HYDROSTATIC HEIGHT IN THE CASTING POUCH, THE HEIGHT SAME HAS CALCULATED IN A CALCULATOR BY INTEGRATION FROM THE FLOWS ALREADY RUN. / P P OF THE AUTOMATIC COMPENSATION DEVICES ALLOW THE COMPENSATION TO BE COMPENSATED OIL LEAKS WHICH OCCUR IN THE JACK 12 EVERY TIME THIS JACK IS LOCATED (OR SHOULD BE FINISHED) AT THE END OF THE RACE. / P
