The ladle on the ladle turret is tapping molten steel into the tundish for continuous casting process - SME Group

Preparation and secondary refining of molten steel in continuous casting process

The biggest feature of continuous casting process is forced cooling of molten steel, solidifying molten steel into billet in a short time. Therefore, the continuous casting process itself has more stringent requirements on the quality of molten steel. It must not only ensure stable and appropriate molten steel temperature and deoxidation…
