Abstract The primary strengthening factors of BOFLFCSPproduced matrix plate for coldrolled products were analysed systematically.Grain refining strengthening is the main factor for such product. Yield strength is correspondingly related to grain size； Through optimization of steel making process,ladle furnace refining and casting process, the average w［Si］ in liquid steel was less than 0.02%, and w［N］ was less than 30×10-6. The control rolling and cooling was used to control dynamic recrystallization and grain growth,beginning and finishing temperature and coiling temperature are three important parameters that affect the strength of product. The strength of matrix plate for coldrolled products was decreased significantly through specific measures.

Key words： CSP strength matrix plate for coldrolling
