Title: Manufacture of shape bar
Inventor: ISHIDA KAZUO
IPC: B21B1/08
Filed: 1983-09-16
Abstract: PURPOSE:To obtain efficiently a shape bar without roughening the surface of a product by rolling a material without substantially subjecting its thick-thickness part to rolling reduction before rolling the material by specifying the draft of its thick-thickness part as compared with its thin-thickness one. CONSTITUTION:A blank material 14 having a cross section close to that of a product is obtained by passing a deformed blank material 13 through a pair of flat rolls. The material 14 is passed through a roll constituted of a flat roll and a grooved roll 41 having a grooved part 42 stepped to have its cross section equal to that of a product in order to finish its shape of sheet-thickness change into the prescribed dimensions. The material 14 can be subjected to rolling reduction so as to make the draft of its thick-thickness part larger as compared with its thin-thickness part within a draft of 5% in accordance with the sheet- thickness ratio thereof. Accordingly, the material 14 is prevented from surface roughening and is elongated to the longitudinal or rolling direction without roughening its surface, and a product 15 is obtained by finishing the material 14 into the prescribed cross-sectional dimensions.
