Characteristics of Fujico Co. Ltd. CPC/HSS Rolls for Hot Strip Mills and Long Bar Mills and Its Application Results

摘要

In the late 1980s a trial with a very small work roll diameter was performed in a hot strip mill (HSM) to improve edge drop of the strip. The trial showed that improvements were very good, but that the small work roll needed to be improved for better wear resistance. High speed tool steels (HSS) were selected for their wear resistance. The continuous process for cladding (CPC) was selected so that (HSS) could be utilized as the shell material. Long bar mill rolls and other mill tools are also being manufactured by this process.
