Abstract

PURPOSE: To form shape section bars and plates efficiently from billets without loss of material by extruding and rolling the respective parts of blank at the same thickness ratios as those at the final molding.
CONSTITUTION: Blank 1 is liquid-pressure-extruded from billet material at the same thickness ratios as those of the molded material 2 of the shape sectional bar or plate at the final molding. Next, while the thickness ratio of each part of the section is being maintained similarly to the above, the blank is rolled for more than one pass by an upper roll 3 provided with a rolling groove 5 and a lower roll 4 being flat plate. Here, it is also possible to roll-form the shape section bars or plates of various shapes by providing grooves or protrusions to the upper and lower rolls 3, 4.
