The invention is directed to a method and apparatus for thermally cutting rectangular metal slabs along a longitudinal axis of the slab. A metal slab is conveyed along a predetermined path of travel while it is being cut by, for example, an oxygen-flame cutting machine. The means for conveying the metal slab comprises a plurality of rollers transversely disposed relative to the path of travel and the cutting machine is arranged above the conveying means and between two of the rollers. The slag created by the cutting is collected and conveyed by a slag duct disposed below the conveying means. Pursuant to the invention, the slag duct extends from between the two rollers adjacent the cutting machine along an axis transverse to the path of travel. In accordance with another feature of the invention, the side edges of the metal slab are sensed and the cutting machine is transversely aligned relative to the path of travel in accordance with the sensed locations of the side edges.

Apparatus for thermal longitudinal parting of rectangular metal plate

The invention refers to a support, drive and guide roller stand for a metal strand casting plant, particularly for a steel slab curved strand casting plant, consisting of several segments with rollers and counter-rollers mounted in separate segment frames. Several rollers are arranged in one common segment frame, whereby one segment frame, carrying rollers, can be set for casting thickness and/or shrinking thickness relative to the segment frame carrying the counter-rollers, and whereby individual rollers are provided whose length is foreshortened vs. the strand width.
