Automation of assembly batches hot rolled of metallurgical production

The paper considers the task of automating the process of forming assembly batches installation in a hot rolling mill. To solve this problem, a developed algorithm for the formation of optimal assembly batches at a hot rolling mill is proposed, taking into account the technological limitations imposed on the production process. The optimization of the set of assembly batches consists in the construction of a set with maximum productivity, which is achieved by reducing the time for the reconstruction of the equipment when switching to different width and thickness of rolling stock. A program for automatic formation of assembly batches at a hot-rolled steel mill has been implemented. It is now possible to save each batch included in the generated set to a separate file, as well as write general information about the entire set to a file. The algorithm was tested when forming assembly batches from a set of slabs available at the warehouse. Calculations on the formation of optimal assembly batches have been carried out. The presented results of the study show the increase of the formed assembly batches productivity and their compliance with all technological restrictions.
