Title: Method of cutting band steel
Inventor: MASUI HIDETO
IPC: B24B7/12
Filed: 1977-12-27
Abstract: PURPOSE:To make practicable the grinding of band steel at a constant grinding amount so as to remove flaws by providing power programs having characteristics varying with the types of belts. CONSTITUTION:A band steel 9 to be ground which is fed at a predetermined speed is ground between a billy roll 8 and a grinding belt 4 driven by a contact roll 5 rotated by an induction motor 15 in a prescribed manner so as to remove flaws thereon. The conditions of grinding are changed by rotating a screw shaft 19 by an electric motor 22, vertically moving a supporting plate 17 by rotation of the screw shaft 19, and vertically moving the billy roll 8 little by little. Also, the grinding power at the time is read from the current value in the induction motor 15 for driving the contact roll 5. Therefore, if a power program is set up by investigating the grinding characteristics of the grinding belt beforehand, grinding may be carried out at a constant grinding amount to remove flaws on the band steel.
