Flame cutting of short slabs in continuous casting plant - using extra rollers in conveyor track so short cut pieces cannot fall through gaps between rollers

摘要

In a first zone of the casting plant, cuts are made in the cast billet or slab; but the cuts only extend through part of the thickness of the slab. The slab then travels through a second zone in which cutting is completed. The cut pieces of slab are next pref. removed at the same speed, or faster than, the casting speed employed for the slab. The pref. plant includes a flame cutting machine clamped to, and moving with, the slab, and carrying several burners, so that several part-cuts can be made in the slab simultaneously. A conventional roller track can be used for cutting short pieces from a slab, by using extra rollers so the short cut pieces cannot fall through the track.
