Title:
METHOD FOR ASSISTING OPERATION OF ROLLING FACILITY, OPERATION ASSISTANCE DEVICE, AND ROLLING FACILITY
Document Type and Number:
WIPO Patent Application WO/2021/024448
Kind Code:
A1
Abstract:
This method for assisting operation of a rolling facility comprises a target rotational speed acquisition step for acquiring the rotational speed fr of a rolling roll, and a step for outputting the acquired rotational speed fr as a target rotational speed. In the target rotational speed acquisition step, the correlation between the rotational speed fr and a characteristic value σ, which indicates an N-gon-forming tendency for the rolling roll to form into an N-gon by being subjected to uneven wear when rolling is performed at the rotational speed fr, is used as a basis upon which to acquire the rotational speed fr that corresponds to a characteristic value σ indicating that the rolling roll is forming into an N-gon in a slowed or attenuated manner.
