Abstract

We present a method of anomaly detection using multivariate statistical process control(MSPC) to detect the abnormal behaviors of a blast furnace. Tuyere cameras attached circumferentially at the lower side of a blast furnace are used to monitor the inside of the furnace and this method extracts abnormal behaviors of intensities. It is confirmed that with our method, detecting timing is earlier than operators’ notice. Besides, misalignment of cameras doesn’t affect detecting performance, which is important property in actual use.
