Combining with the study of analogue experiments and test analysis, the kinetics of precipitation and growth of AlN and MnS in nonoriented electrical steel produced by the CSP process is calculated. The results show that the precipitate phase particles of AlN and MnS in typical nonoriented electrical steel grades produced by the CSP process have grown to some extent in the soaking stage, but the precipitation contents are less than 20% of the total contents of nitride and sulfide. The precipitate phase particles of AlN and MnS have precipitated almost after the hot rolling process. The precipitation contents are more than 80% of the total contents of nitride and sulfide, but it is very late for the precipitate phase particles to grow at the end of the hot rolling process.
