Large diameter pipe and structural section mills need to maintain a high uptime operation. Change over times must be kept to a minimum, the break-down section of the Kusakabe Universal Forming Mill requires no roll changes, the fin passes use the patented cassette roll change system which is extremely fast, the same system is also used in the sizing section. The result is a mill where the changeover times are fast and the mill spends more time manufacturing product for the market. The Kusakabe Milling Cut-off produces a square cut end face and length control where the finished product can be supplied directly to the customer for structural pipes and sections without any additional work.
