Abstract. Tata Steel, Meramandali faces severe clogging issues due to which tube change at the nozzle occurs at a frequency of 2 heats. A need for prior intimation to the operator of clogging in IF grade heats (Interstitial free) was required. An anomaly detection system was developed which consisted of exponentially weighted moving average coupled with moving average-standard deviation resulting in 98% accuracy due to composite signal processing arising from dual thresholding causing a benefit of 1.43 Cr due to increase in tube change frequency from 2 heats to 3 heats
