AI Technical Summary

Technical Problem

When the aluminum foil rolling mill produces ultra-thin double-zero aluminum foil, it is extremely difficult to start and increase the speed of the hot rollers, resulting in frequent strip breakage, affecting production efficiency and equipment operation rate.

Method used

A spray system is installed at the entrance of the rolling mill. A rolling oil mixture made by mixing acid additives with base oil is sprayed onto the surface of the aluminum foil through a spray nozzle. The oil supply parameters are adjusted to reduce dilution and ensure the lubrication effect, and then the system is switched to the normal oil supply mode of the base rolling oil.

Benefits of technology

It effectively solves the problem of difficulty in starting and speeding up the hot roller, reduces downtime, improves equipment operation rate and production efficiency, and reduces roller consumption and production waste.

Abstract

The invention belongs to the technical field of aluminum foil production, and relates to a method for solving strip breakage caused by abnormal speed starting of a hot roller of an aluminum foil mill, which comprises the following steps of: configuring a spraying system, preparing and spraying a rolling oil mixed solution, setting low oil supply parameters, and switching to a normal oil supply mode after the speed of the mill reaches a target working speed. The problems that when an aluminum foil finishing mill, especially a wide rolling mill, produces ultrathin double-zero aluminum foil, the hot roller is difficult to start and speed up, and a belt is broken are solved, the ultra-long downtime caused by starting failure of the hot roller is shortened, the equipment operation rate and the production efficiency are improved, the labor intensity of an operator of the finishing mill is relieved, and the capacity of the wide rolling mill is brought into full play. And the working time of the working roller is obviously prolonged, the dependence on the standby roller and the replacement frequency are directly reduced, and the roller consumption and the production waste caused by frequent shutdown and belt breakage are reduced.
