TFP(Trimming Free Plate)製造技術の開発

概要

The presented rolling techonology aims at supplying heavy plates without edge trmming by incorporating an attached edger close to the finishing mill. Technical subjects for realizing this object include; rolling force and torque in V rolling, prevention of buckling in heavy width reduction, elimination of edge overlap by chamfer rolling, and overall rolling strategy. These subjects are first examined in experiments by lead model, and an production mill is constructed. Important features and some experiences in the production mill are summarized below; suggesting the promising future of the present technology. 1) The V roll has a caliber part as well as a flat part in order that the edge can be shaped in square by selective use of either part according to the rolling pass by roll shifting. 2) The overall rolling strategy including V rolling is supported by accurate AWC system, and is effective for attaining high width accuracy over the whole length of rollling material. 3) Width loss can be drastically reduced by chamfer rolling and finish-edging combined.
