Title:
ROLLER TABLE ALUMINUM PICKUP CONTROL METHOD BASED ON MICRO TORQUE OF DRIVING ROLLER
Document Type and Number:
WIPO Patent Application WO/2022/083263
Kind Code:
A1
Abstract:
A roller table aluminum pickup control method based on micro torque of a driving roller, the method comprising: selecting, in areas near to two sides of a rolling mill, a driving roller separately driven by an individual electric motor to serve as an experimental roller; conducting an experiment on the driving roller, and selecting, according to an on-site roller table situation, a set of transfer roller tables as roller tables to be corrected; in a system, modifying a driving roller speed control mode during the rolling process, and retrieving process data of normal production; and when speed mismatching occurs between a rolled piece and the transfer roller table, correcting a set speed value of the transfer roller table or a drive mode of the transfer roller table. By means of the method, the speed control mode of a driving roller during the rolling process is modified, and the speed of the driving roller is compared with the speed of a transfer roller table to be corrected, so as to verify the speed matching between a rolled piece and said transfer roller table, and the speed of said transfer roller table is corrected, such that the number of defects, i.e. roller table aluminum pickup and scrapes and scratches on the surface of a rolled piece, which are caused by speed mismatching between the rolled piece and a transfer roller table, can be reduced.
