Online feedback control method and device for short-process production line and electronic equipment

Abstract

The invention discloses an online feedback control method and device for a short-process production line and electronic equipment. The method comprises the following steps of acquiring historical data of the short-process production line; establishing a short-process production line database according to the historical data of the short-process production line; refining metallurgical specifications of a manufacturing system; obtaining new product development data of the short-process production line; and performing online feedback control on the short-process production line according to the short-process production line database and the new product development data. According to the online feedback control method and device for the short-process production line and the electronic equipment, on the basis of actual performance data such as variety components, process and performance of the short-process production line in recent ten years, real-time calling of process data and reminding and alarming of abnormal conditions are realized in combination with a manufacturing system (overall production and marketing system ERP), L2 and the like, and the method and device are simple and easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of structure and performance prediction of hot-rolled strip steel, and in particular relates to an online feedback control method, device and electronic equipment for a short-process production line. Background technique [0002] The microstructure and performance prediction technology of hot-rolled strip rose in the 1970s. With the development of iron and steel enterprises, its application prospects are very broad, and it has been valued by many iron and steel enterprises at home and abroad. The fundamental principle is to use physical metallurgical models and computer and information technology to conduct comprehensive numerical simulations of various physical metallurgical phenomena in the hot rolling production process, quantitatively describe the microstructure evolution process, and predict the microstructure and mechanical properties of the rolled products. performance.

Problems solved by technology

[0007] Due to the rigid connection between continuous casting and steel rolling in the short-process production line, when there is a deviation in the composition control of molten steel, if the pouring is interrupted, the production will be interrupted, and the production rhythm will be disrupted. The subsequent molten steel needs to be reheated and treated, resulting in poor quality of molten steel; If casting is forced, due to the uniqueness of the manufacturing system process, the performance may be changed and the judgment may be changed, resulting in quality loss
