Abstract
PURPOSE: To quickly form the steel shape with a small power, and to improve the production efficiency, by installing the roll forming mill behind the hot rolling mill line for the hot strip.
CONSTITUTION: The steel strip 1 is rolled by the finish rolling mill 2, and is succsesively sheared by the flying shear 3 into the required length. The sheared strip is carried by the roller 4, and is fed to the roll forming mill 7 through the pinch roll 6; then, the strip is given a gradual deformation by a series of the forming rolls; and the steel shape of the required shape from the final forming roll. Thus produced steel shape is passed through the carrying and cooling zone and is finished to the final product. In the present method, since the steel strip is formed under the high temperature condition in succession to the hot rolling, the production of the steel shape is carried out efficiently, and besides, it is possible to manufacture the steel shape of the hard material.
