Roll flattening. The workpiece passing between a pair of rolls is compressed by the radial stress in them, but the reaction is transferred to the mill bearings and housing, which are capable of …

2018年4月15日 · In this study, stainless steel sheets were cold-rolled and the profiles of the partly rolled specimen were measured by a laser profilometer. Meanwhile, data processing method …

Mechanical Fatigue by mechanical compression (flattening) and physical distortion (deflection) caused by the rolling force and the necessary torque applied by the motor.

Flattening Rollers. Flattening or Leveler rollers require high strength and durability as they are used in the level or “flattening” of steel or other hard metal or cement/asphalt surfaces.
