Description:

The roll is double poured indefinite chill iron,  produced by vertical spin casting process, heat treated at low temperatures to obtain favorable stress levels and the required hardness range. This material properties provide a good resistance against thermal and mechanical impacts due to rolling incidents. Meanwhile, the characteristic hardness drop of indefinite chill rolls is minimized by the manufacturing process.
