The invention relates to the technical field of hot rolling, in particular to an implementation method for a material backup roll of a finish rolling working roll of a rolling line.

Background

The spare roll of the finish rolling working roll means that the finish rolling working roll meeting the requirements is selected according to the spare roll requirement of the rolled steel type to be used on a machine, and the traditional process of the spare roll of the finish rolling working roll is realized by adopting paper roll changing single exchange information. Because the high-speed steel work roll is resistant to surface roughness and abrasion resistance, the work roll can be ground for one time and used for multiple times, and after the work roll is used for multiple times, the surface of the work roll has the defect that an oxide film is peeled off or the abrasion is large, so that the work roll needs to be different in requirements on roll surface quality and plate type of different steel types, and different in standby use times and surface grades, namely, the work roll is prepared according to the material. When a rolling plan is issued each time, rolling line operators provide roller standby requirements for the rolling line operators in a telephone or face-to-face notification mode according to rolling varieties, the rolling line operators select rollers meeting requirements from turnover rollers according to the rolling line requirements, fill the rollers in paper roller changing lists and send the rollers to a rolling line operating platform, the rolling line operators input information into a rolling line control system, and after rolling planning is finished, the rolling line returns the paper roller changing lists to the rolling line.

The traditional finish rolling working roll standby flow is completed in a paper roll changing single mode, and has serious defects, one is that the standby roll is large in quantity, 3 thousands of rolls are loaded and unloaded each year, information such as roll numbers, surface grades, use times, roll diameters and the like is manually filled, the workload is large, the error rate is high, and particularly when temporary roll changing occurs, the standby roll flow needs to be completed within ten minutes, and errors are easy to occur; and secondly, when the information communication of the backup rolls among personnel is not timely or the backup rolls are deviated, the backup rolls do not meet the requirements of rolling varieties and need to be prepared again, the workload of operators among the grinding rolls is increased, and the production efficiency of a rolling line is influenced.

Aiming at a hot rolling production line, the number of the rollers on and off is large, and when an operator fills a roller list between the grinding rollers and inputs a rolling line operator into a rolling line control system according to roller list information, the rolling line shutdown accident is caused by multiple data errors every year; in addition, because the operators of the rolling line cannot inform the operators in time, the rolls are prepared between the grinding rolls, and the operators of the rolling line do not agree with the rolling machine, the rolls need to be prepared additionally, so that the repeated labor is caused, the workload of the operators between the grinding rolls is increased, and the normal production process of the rolling line is seriously influenced.
