METHOD FOR CONTROLLING LINE SPEED ON ENTRANCE SIDE IN WELDING RELATED OPERATION

摘要

PURPOSE: To provide a line speed controlling method on the entrance side in a welding related operation in a continuous cold rolling mill which is capable of utilizing the maximum of a loop storage quantity including stationarily generated deceleration of a rolling speed and displaying the production capacity of the rolling mill at its maximum. ;CONSTITUTION: In this method for automatically welding billets successively and for continuously rolling a strip on the entrance side of a continuous rolling mill, a rolling speed pattern in which a loop storage quantity is utilized at its maximum is computed and set in accordance with each of the following items, the position of a loop car, maximum rolling speed (capacity limit of equipment), estimated time Th until the completion of a welding related operation, presence/absence of deceleration of rolling speed and its timing within such estimated time Th as well as its deceleration pattern (Td, Vd).;COPYRIGHT: (C)1995,JPO
