ABSTRACT:
A method of and apparatus for continuously hot rolling steel slabs. Separate pieces of steel slabs are continuously fed from a slab yard and delivered to a carriage which is adapted to move reciprocatingly along the line of path of the steel slab pieces. The carriage carries a welder which can move transversely of the path of the slab pieces, and also clamp devices for clamping preceding and succeeding slabs to fix them to the carriage, as means for keeping the preceding and succeeding slab pieces in abutting condition. As a steel strip including a plurality of slab pieces welded together is moved at a predetermined rolling speed into a rolling mill, the carriage moves substantially at the same speed to keep the succeeding slab in abutment with the trailing end of the last slab piece of the steel strip, to permit the welder to weld these slab pieces at their abutting end. This welding is performed only over a part of the cross-sectional area of these slab pieces. The steel slabs are thus welded together into continuous form, delivered to the rolling mill and rolled by the latter. This system ensures a higher yield of products and permits a full continuous hot rolling of the steel slabs.
