AI recognition of hot-rolled steel surface defects
Baosteel's hot-rolled surface-defect model reached 96% accuracy and spread to multiple production bases
Problem
Baosteel needed to identify surface defects in hot-rolled steel during production.
Approach
Baosteel deployed an AI model for hot-rolled product surface-defect recognition. Its broader industrial AI program included collaboration with Huawei. The surface-defect model reached 96% accuracy within 6 months and was replicated on production lines at multiple bases.
Results
Takeaway
Baosteel expanded the model beyond an initial production setting. It did not disclose the test set or false-rejection rate behind the accuracy figure.
