Clogging behavior of submerged entry nozzles during non-oriented silicon steel（with aluminum content of 0.3%~0.4%）casting by BOF-LF-RH-CSP process in a domestic steel mill was investigated.By way of systematical sampling,optical microscope observation,SEM analysis and mineralogical phase analysis,the structure and compositions of the clogging substance were identified and the clogging mechanism was briefly clarified.It was found that the process of Ca treatment,which generated a lot of CaS,was the major factor to clogging.By improving the production process,the sequential heats during non-oriented silicon steel casting by CSP process increased from 5 to 8 or above,resulting in higher production efficiency without sacrificing the requirements of quality.
