The oxygen content at end point of ultra-low carbon steel is directly related to the subsequent fabrication processing and quality of final product. The bottom blowing in the process of converter smelting and the calculating parameters of sublance model system are optimized by company so that the intensity of bottom blowing gas supply is increased, stir of bottom blowing to molten pool is strengthened and bottom blowing gas supply mode is established for ultra-low carbon steel. The results showed that the oxygen content at end point could be reduced, hit ratio of carbon content as well as temperature and oxygen content for ultra-low carbon steel at end point could be improved with the above process, which could provide better molten steel for the subsequent processes.
