Initial rolling temperature is a core process parameter in hot strip rolling mill production, determining steel quality, rolling efficiency, and equipment wear. Its setting must be closely integrated with the chemical composition, microstructure, and rolling objectives of the steel grade to achieve precise control of “temperature-adapted steel properties.” Different steel grades exhibit significantly different initial rolling temperature ranges due to differences in alloy element ratios and phase transformation laws. Scientific setting is crucial for ensuring stable production and product quality.
