Patent ID: 7762312

Claim:
Method for driving support rolls ( 7 c ) of a continuous casting machine for liquid metals, which support rolls form a strand guide ( 7 ) for a continuously cast strand ( 1 ), which strand guide comprises electrically driven individual support rolls ( 7 c ) and/or hydraulically adjustable support roll segments ( 9 ), comprising the steps of: using an automatic load balance control system ( 12 ) for all drives ( 10 ) as a sum of individual forces for casting speed, motor torque, motor speed, and standard correction factors; providing the control system with individual adjustment of torque and speed of each drive support roll motor; determining a total driving torque for all drives ( 10 ) from a normal force of the driven drive support rolls ( 7 c ); and proportionately transmitting the total driving torque to each support roll ( 7 c ) in such a way that a static base setting of torque distribution is used as a basis for the specific load capacity of each drive support roll ( 7 c ).
