In this study, we measured the temperature at the tip of the lance in blast furnace and analyzed heat transfer to understand the actual situation, and observed the cross section of the actual lance with Scanning Electron Microscope - Energy dispersive X-ray spectroscopy (SEM-EDS) to examine the choke mechanisms. As a result, it was confirmed that the pulverized coal blowing lance of a blast furnace is exposed to high temperature, especially at the tip of the lance. It was also suggested that the growth of oxide layers on the inner surface of the lance and the resulting unevenness were related to the adhesion of pulverized coal particles.
