Embodiment Construction

[0015] This embodiment provides a data-driven method for optimizing the scale length of wide and heavy plates. Taking a single-stand wide and heavy plate rolling mill as the research object, the scale length of its production process is optimized. The process parameters of rolling equipment and products are as follows : Rolling mill type: single-stand four-high rolling mill; work roll length: 5000mm; work roll diameter range: 900-1150mm; billet thickness: 300mm; plane shape control: the control system has the plane shape control function.

[0016] ① Extract data, determine the key factors affecting the length of the ruler and its upper and lower limits

[0017] According to the three key factors of the thickness of the finished product, the length of the finished product and the width ratio, the corresponding length data of the scale is extracted from the scale layer table of the current production application, such as figure 1 shown. A total of 449 groups of initial data wer...

Abstract

The invention discloses a wide and thick plate ruler placing length optimization method based on data driving, relates to the technical field of steel production, and is mainly applied to the aspect of rolling length ruler placing control. A unified and continuous ruler placing amount calculation module is established, the problems that the ruler placing standard is difficult to refine and blanksare wasted due to the fact that an existing rolling length ruler placing mode adopts manual experience and a sectional type extensive mode are solved, the steel plate rolling yield is increased, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a data-driven method for optimizing the scale length of wide and thick plates. Background technique [0002] At present, the varieties and specifications of thick plate hot rolling mills are constantly expanding, and the precision of dimensional control is constantly being optimized. At the same time, the steel situation requires continuous improvement in reducing production costs. For the control of the scale length of products of different specifications in the thick plate hot rolling mill, it is still compiled manually based on experience, and there is room for further optimization. The scale standard programmed by manual experience adopts a fixed-value segmented scale measurement, which is difficult to maintain. , resulting in a large amount of waste of steel, which restricts the improvement of the yield of rolled steel. Contents of the invention [0003]...
