Abstract: A process and an ultracompact plant for the endless production of hot rolled steel strip comprising an ingot mould (15) that produces a very thin slab, having narrow sides with thickness in the range between 40 and 55 mm and a central swelling, at a speed in the range between 4 and 16 m/min. Such a slab, which displays a core in which the steel is still liquid, is passed through a vertical pre-rolling device (16) that reduces the thickness of the slab and flattens it. The solidified slab may thus be subjected to a first mild rolling by a conveyor (17) and, by forming a free curve, takes a horizontal position where it is subjected to a first surface descaling, a first rolling, a heating in an inductor (23), a second surface descaling and a series of reductions in a rolling mill (30) formed by at least two stands, by maintaining its temperature along the mill above the recrystallisation point Ar3. Downstream of the rolling mill (30) there are provided a roller runway with cooling showers, a flying shear (33) for cutting to length the strip produced, pinch rolls and at least two spinning wheels (34) for the formation of coils of the hot rolled strip.

Abstract: A hot rolling method which, even if an abnormality occurs before, during or after the joining of metal pieces, does not need to stop the operation of the line. The method is such that if, at the inlet side of a finish rolling machine (26), the leading end of a following metal piece is to be joined to the trailing end (10B) of a preceding metal piece so as to be subjected to finish hot rolling continuously with the preceding metal piece (10), it is decided whether or not endless rolling is possible before and after joining and if it is found impossible, joining is suspended and the following metal piece (12) is stopped so that after the trailing end (10B) of the preceding metal piece has passed through the finish rolling machine (26), the following metal piece (12) is retransferred and finish-rolled with a setting for batch rolling, and if an abnormality occurs in the joined portion after the joining, the joined portion (11) is cut off between the joining device and the finish rolling machine (26), and the material to be rolled is fed into the finish rolling machine with a setting for batch rolling.
