Abstract
A plant for slitting a hot slab, emerging from a continuous casting machine, by means of band sawing machines of which two or more are guided in the serial direction of the slab and are slidably guided transversely to the slab feed direction so that saw changing can be performed in a position outside the rollers of the roller table. Normally, all band sawing machines are in the operating position so that a second, third and so on band sawing machine continues the slitting cut if the saw blade of the preceding machine breaks. The band sawing machines are conveniently provided with one-sided, C-frames, each of which has at least three cantilevered guide rollers for the saw blade, of which one roller is driven.

A method for slitting a hot slab emerging from a continuous casting plant advancing on a roller table comprising the steps of:
- (a) providing a plurality of band saw means, each having a saw blade;
- (b) serially positioning said blade of each of said band saw means one behind the next in a single cutting path, the first blade in the direction of said emerging slab being the leading blade, and the blades positioned therebehind being succeeding blades;
- (c) advancing the emerging slab;
- (d) cutting the advancing slab with the leading blade of the serially positioned blades;
- (e) providing means on each blade for removing said leading blade in the series when said leading blade breaks;
- (f) continuing to advance the slab when said leading blade breaks;
- and
- (g) cutting said advancing slab with said succeeding saw blade.
An apparatus for cutting a hot slab emerging in a longitudinal direction from a continuous casting plant advancing on a rolling table comprising:
- (a) a plurality of band saw means each having a blade;
- (b) each blade being positioned serially one behind the next in a single cutting path in the longitudinal direction of the advancing slab, the first blade in the direction of the emerging slab being the leading blade and the blades positioned therebehind being succeeding blades;
- and
- (c) means on each succeeding blade for removing said leading blade when said leading breaks.
