What exactly is Mill Scale and what is done about it
Mill scale is found on all hot-rolled steel products unless processed in a protective atmosphere or descaled (e.g., for galvanizing). At hot rolling temperatures, an inner layer of wüstite, FeO, exists between the steel and magnetite.
Hot Rolling Mill Rolls - UKOCarbide
They are generally heated to 1100 to 1250°C for rolling. This rolling process is called hot rolling. The termination temperature of hot rolling is generally 800 to 900°C, and then it is generally cooled in air, so the hot rolling state is equivalent to normalizing treatment. Most steels are rolled by hot rolling.
