For the blanking problem of transformer silicon steel sheet, an integer programming optimization model for the blanking problem with the least material consumption as the optimization goal was established, and the model was solved by a blanking algorithm based on the sequential correction of remaining material utilization rate. Then, the algorithm adopted a reasonable and effective strategy for the utilization and generation of remaining material, and the remaining material with the same width was considered to be the same kind of remaining material. Furthermore, the inventory backlog was avoided by restricting the type and total number of the remaining material, and the material utilization was improved by splicing silicon steel sheets with the same width. Compared with the other published algorithm, it is proved that the proposed algorithm can effectively improve the material utilization ratio under the premise of ensuring reasonable running time, and the effectiveness of the algorithm is further verified by running a production example. Therefore, the proposed algorithm can be used to guide the blanking process of transformer silicon steel sheet, which has great practical value for improving the economic benefits of enterprises.
