Problems solved by technology

However, most of these methods only consider the problem of thickness distribution, and do not consider rolling parameters such as speed and tension, and generally optimize the thickness of a fixed number of passes. process
On the other hand, when the optimization algorithm is added for online optimization, its calculation time is longer, which is not conducive to online application

Embodiment Construction

[0089] The invention proposes a method for formulating a rolling schedule for an aluminum single-stand cold rolling mill, and the rolling schedule is formulated on the basis of the rolling specification.

[0090]According to the rolled material and specifications, after the rolling specifications are automatically generated or obtained from the rolling specification database, the pass planning system determines the overall pass and annealing pass arrangement, and the thickness distribution system completes the uncertain pass number of each pass section. Thickness allocation of each pass, combined with the tension system and speed system to complete the design of rolling parameters such as thickness, tension, and speed of each pass, and check the force and energy after generating the rolling schedule, and adjust the rolling specification until each rolling schedule The rolling parameters meet the process constraints, and the rolling schedule is output, such as figure 1 As shown...

Abstract

The invention relates to a rolling procedure making method of an aluminium single-stand cold-rolling machine, in rolling specification obtained by a rolling specification library according to the rolling material and specification, four system parameters are included to be suitable for the characteristics of rolling process of an aluminium single stand, and annealing, thickness, tensile force andspeed parameters in each pass can be respectively determined; the rolling specification is formed by a pass programming system, a thickness distribution system, a speed distribution system and a tensile distribution system, the specification of the rolling material carries out rolling procedure making by obtaining the rolling specification by the rolling specification library, so as to realize automatic generation of the rolling procedures of different materials with different width and thickness specifications in the production process of the aluminium single-stand cold-rolling machine and carry out rolling procedure making. The method has strong practicality, and can automatically realize rolling procedure making for different materials and specifications; the method is simple and practical, has high computing efficiency and rapid speed and is suitable for on-line usage.

Description

technical field [0001] The invention relates to a strategy for formulating rolling schedules in aluminum cold rolling production, in particular to a method for formulating rolling schedules applied to aluminum single-stand cold rolling mills. Background technique [0002] Aluminum single-stand cold rolling mill is a kind of rolling mill that is widely used in domestic aluminum processing enterprises. Compared with continuous cold rolling mill, its investment is small and the rolling production process is more flexible. It is suitable for the production of aluminum strips of various varieties and specifications. production to meet market demand. Due to the flexibility and variability of the production process of aluminum single-stand cold rolling mills, the formulation of rolling schedules is also specific, and its research is relatively less than that of continuous rolling mills. At present, in the production of many single-stand cold rolling units, there are many unreasona...
