In view of the problems of the violent crown fluctuation and unstable shape control in the endless rolling production line, the field measurement results show that the abnormal crown fluctuation is related to the shifting limit position of the work roll after the uneven wear occurs. For this reason, the asynchronous roll shifting strategy is developed, which has double attenuation of roll ...

Camber — or, to be more technical, "camber angle" — is the angle between the vertical axis of a wheel and the vertical axis of a vehicle. Put another way, it's whether or not your tires lean towards or away from the car when viewed from the front of the vehicle. If the top of the tire leans towards the vehicle, the car is said to have ...

The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.
