The formation reson of the surface defect of 0Cr18Ni10Ti after rolling is analyzed, some improving solutions are performed for avoiding the surface defect and enhancing the production quality. The investigation shows that the surface defect of rolled steel is mainly ascribed to the inclusions containing Ti, and TiO2 and TiN is a primary source of inclusions in the steel. An effective way of reducing the inclusion performed is decreasing the Ti and N content in liquid steel. By appropriately increasing the carbon content of molten steel entering into the AOD, decreasing the carbon content of the end of blasting oxygen, slag skimming in the ladle and slagging in LF furnace, feeding SiCa wire before Ti alloying in LF furnace and optimization of Ti alloying method and protection casting with no oxidation, the yield of Ti is greatly increased, the TiO2 and TiN inclusions is controlled better, the quality of products 0Cr18Ni10Ti all are greatly improved. The number of continuous casting furnace is increased from one to the three furnace, and the production efficiency is obviouly enhanced in TISCO.
