Rolling schedule generation method for aluminum cold rolling mill based on material state and parameter curve

Abstract

The invention relates to an aluminum cold-rolling mill rolling schedule generation method based on material states and parameter curves. The method includes determining intermediate annealing process parameters in a rolling schedule in terms of a material finished product state according to raw materials and finished product parameter requirements of aluminum rolls, determining process parameters such as the times of rolling passes, thickness of each pass and rolling speed according to the parameter curves, then calculating rolling schedule control parameters according to a mathematical model, and checking and correcting according to mechanical parameters of a unit so as to automatically generate the rolling schedule of the aluminum rolls. According to the method, after finished product definition and parameter curves of a certain material are determined according to process requirements and empirical data, automatic rolling schedule generation aiming for aluminum rolls made of the material and in various dimensions can be realized, maintenance and extension according to materials are facilitated, and a systematized rolling schedule generation technique is formed.

Description

technical field [0001] The invention relates to a method for formulating a rolling schedule suitable for an aluminum cold rolling mill, in particular to a method for generating a rolling schedule for an aluminum cold rolling mill based on a material state and a parameter curve. Background technique [0002] At present, there are few studies on the formulation of rolling schedules for aluminum cold rolling mills, and there is a lack of mature and reliable rolling schedule formulation methods with strong production practicability: First, the formulation of rolling schedules is mostly based on manual experience and lacks systematic Second, the aluminum cold rolling process factors cannot be considered comprehensively and systematically, and most of the pass allocation is only carried out from the perspective of thickness, without considering the requirements of the finished product state, and the same significant impact on the rolling process Process parameters such as speed an...
