    2021-4-22  In a blast furnace operation under low percentage of reducing materials, which intends to rationalize, the fur-nace condition easily falls into unstable. Therefore, it is important to operate the furnace with a better under-standing of the current condition. However, information obtained from sensors is not still enough. Accordingly, techniques for particle size measurement of charging coke in real time, prediction of pig iron temperature based on blast furnace physical model, and furnace con-dition detection based on inner pressure data of the blast furnace have been developed by utilizing data science technique. These techniques contribute to the detecting the anomaly causing troubles in advance with the guid-ance to operator for preventing a blast furnace
