In this article, the effects of key hot rolling process parameters on the properties of hot dip galvanized extra deep drawing IF steel for home appliances are studied combining with production practices. The analysis on the texture, me-tallographic structure and mechanical properties of test steel at finishing rolling temperatures of 880 ℃ and 915 ℃ as well as coiling temperatures of 680 ℃ and 710 ℃ separately are carried out. The study results revealed the correlation between different hot rolling process parameters and texture, metallographic structure as well as mechanical properties of finished product of hot dip galvanized extra deep drawing IF steel for home appliances, which could be as the reference for improving the properties of hot dip galvanized extra deep drawing IF steel products through establishing reasonable hot rolling process.
