Abstract:
The characterization of coils is the process in which it is necessary to evaluate the characteristics of coils that have been declassified, that is, are not allocated to a sales order, to align them with commercial technical standards that allow for their sale. These characteristics include dimensions, chemical composition, mechanical properties, quality, and applicability. Since each coil has individual characteristics, the evaluation process is also individual, resulting in a laborious and error-prone task that can lead to accidents for customers. Therefore, it is crucial to automate the characterization process, not only due to the speed of the process, which leads to greater stock turnover and increased sales potential, but also to mitigate risks. The automation was achieved by using real values from hot-rolled coils measured throughout their manufacturing process, comparing them with tables containing the values and tolerances for each applicable technical standard, based on the translation of business rules into the program algorithm. Over six months, the volume of material available for sales increased by 738%, and the volume of liabilities decreased by 84%, with a 45% reduction in declassified stock of this product at ArcelorMittal Brazil and a 67% increase in stock sales revenue, justifying the investment in this project.
