PURPOSE:To reduce crop losses by cutting the front and rear ends of a slab into projected and recessed plane shaped respectively and edging the slab between a pair of anvils opened and closed periodically. CONSTITUTION:A gas cutter provided with a computer for controlling the speeds in both casting and width directions is disposed at the outlet side of a continuous casting machine. The front and rear ends of a slab are previously cut into projected and recessed shaped respectively to form a continuously cast slab 2 by synchronizing the speeds of cutter in both directions with a continuous casting speed. Anvils 1, 1 are periodically opened and closed at an amplitude 2(a) and a frequency (f) by synchronizing their motions with the casting speed, and the minimum distance between them is set to a prescribed width W1. The slab 2 is fed between the anvils 1, 1 and is pressed by a whole length edging system. In this way, the cut off part of the front and rear ends of slab 2 are reduced, that is, the crop loss is reduced. |
