During the sintering process of iron ore, due to the long production line and multiple procedures, there is always a delay in control which can lead to defects on the sintering surface. To solve this problem, we propose a novel algorithm called TCUE that predicts these defects based on time compensation mechanism. The algorithm exploits various decision tree algorithms to calculate feature importance, which helps it determine the optimal time lag for each feature and compensate for any delays accordingly. Furthermore, UMAP is used for dimensionality reduction to simplify the calculation. Finally, we employ a kernel extreme learning machine for classification. Our experimental results have shown that TCUE can accurately predict whether cracks will appear on the sintering surface. It outperforms other common machine learning methods, making it suitable for large-scale deployment in factories.
