Recently it is required to improve the cutting performance of crop shears in hot strip mills. This paper shows the development of a new drum-type crop shear which is characterized by the differential speed cutting mechanism. The effect of this mechanism is proved by shearing tests of heated steel (at a temperature ranging between 800℃ and 1100℃) using an about 1/2 scale test machine. It is confirmed that this shearing method has such advantages as stated below, compared with the conventional drum-type crop shear, and can improve the cutting performance as expected. (1) Shearing surface has less "curl deformation" and "burr" (2) Thrust force, which is the cause of interior shearing, is effectively reduced to an amount between a half and a quarter, and the critical clearance can become twice as large as on the conventional drum-type crop shear.
