| Abstract: |
| Water nozzle clogging of tundish is analyzed, and in order to reduce water nozzle clogging and improve the quality of steel, countermeasure is discussed. Cutting off the water nozzle cross-section of the heel, taking a sector and making a polished section, and observing its microstructure with optical microscope, determining the composition of different phase with scan electron microscope. According to the above, the cause of water nozzle clogging is researched, and the measure to avoid water slot heel is put forward. |
