A materialto be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material, close to the transfer line from above and below the material, in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material, are transferred from the upstream to the downstream side in the direction of the transfer line.

A high-quality hot rolled steel sheet is manufactured with a high production efficiency and a low cost, from a long, hot slab, using a combination of continuous casting facilities and a plate reduction press machine.

Apparatus and methods for manufacturing hot rolled steel sheets

The die changing apparatus for a plate reduction press machine, comprises an upper die support holder,and a lower die support holder,that are arranged vertically on opposite sides of a transfer line, and support holder guide rails,installed on the upper die support holder and extending substantially horizontally in the lateral direction of the transfer line, and an upper die,and a lower die,are mounted on the upper and lower die support holders, respectively using the rollers onto the dies, fixing devices,that fix the upper and lower dies on the upper and lower die support holders, respectively, die fastening members,which are placed on each side of the upper and lower dies, opposite each other in such a manner that they can be fastened to both dies, and a die changing mechanism that can move one of the die fastening members in a direction perpendicular to the transfer line.
