Process setting method for single-frame double-coiling aluminium hot-rolling mill

Abstract

The invention provides a process setting method of a single-stand aluminum hot rolling mill with two coilers. A corresponding rolling schedule setting model is established according to the technical features of the single-stand aluminum hot rolling with two coilers; the rolling schedule setting model program is complied into a dynamic link library; a memory sharing manner is adopted to the data sharing of each setting model program; WINCC is adopted as an invoking platform in all programs of the dynamic link library; the WINCC and basic automatic grade adopt Ethernet communication, have the functions of data collection, setting program invoking, setting model self-studying, rolling line tracing, and the like and realize the automatic setting and online modification of the schedule of single-stand aluminum hot rolling. The method obviously increases the quality precision such as thickness, convexity, and the like of aluminum hot rolling strip coilers and adequately ensures the stability of aluminum hot rolling single-stand production.

Description

technical field [0001] The invention relates to a process setting method in aluminum hot rolling production, in particular to a process setting method applied to a single stand double coil aluminum hot rolling mill. Background technique [0002] The single-stand double-coil aluminum hot rolling mill is a kind of rolling mill that is widely used in China in the 21st century. Because its investment is smaller than that of continuous rolling, it can provide billets with better rolling performance. But at present, in the production of a single-stand double-coil aluminum hot rolling mill, the automation level is low, and the setting and control are basically based on manual experience. Due to the different operating levels, the product quality, especially the thickness, crown, temperature and other properties, cannot be guaranteed. It is guaranteed that the production efficiency is not high due to unstable production, and the production profit of the enterprise is affected. [0...

Problems solved by technology

[0004] In view of the characteristics of single-stand rolling, especially in single-stand aluminum cold rolling, there are also related automation drive companies abroad that have developed process setting systems, but they also face the disadvantages of high cost of setting software and are not suitable for promotion.

However, for single-frame double-coil aluminum hot rolling, there is no good and easy-to-promote process setting method and system.
