Actuator

Result

Hydraulic roll force cylinders

Top position accuracy for close thickness tolerances and compensation of wedged strip profiles

Wedge adjustment system

Stepless passline adjustment; low wear for lower costs

CVC^® plus roll shifting

Precise roll-gap setting for full utilization of roll bending system and fewer off-gauge lengths

Enhanced shifting system (ESS)

Edge drop reduction with edge-oriented intermediate roll shifting combined with CVC^®

Work / intermediate roll bending

Accurate roll-gap adjustment combining CVC^® and bending to produce flat strips

Edge Drop Control (EDC^®)

Mechanical reduction of work roll diameter together with work roll shifting ensures constant strip profile right up to the edges. Higher yield because of lower trimming losses

Multizone cooling system

Smoother out more severe flatness defects by cooling particular roll surface areas

Dry strip system (DS system)

Top surface quality by efficient removal of roll coolant, even at high rolling speeds
