Abstract: A process and an ultracompact plant for the endless production of hot rolled steel strip comprising an ingot mold (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 recrystallization 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 continuous hot rolling method includes setting operating conditions (OC) for hot rolling facilities, regarding rolled material for which endless rolling was planned, in which a preceding piece of material and a subsequent piece of material are joined to each other, to batch rolling, in which rolling is performed without joining the preceding piece of material and subsequent piece of material to each other, or setting of changes from batch rolling to endless rolling. Changes can be speedily and accurately made, so that operating problems, or defective coils due to inaccurate changes in settings or delays in changing the settings can be prevented. Both the operating conditions (OCIe) for endless rolling and the operating conditions (OCIb) for batch rolling are predetermined, and the operating conditions (OCe,OCb) for the facilities at various positions on the hot rolling line are determined for both endless rolling and for batch rolling.

Abstract: The present invention eliminates the need to stop the operation of a line even when trouble arises before, during, or after an operation of joining metal blocks in hot rolling. According to a specific solving means of the present invention, when a succeeding metal block is to be subjected to hot finish rolling in succession to a preceding metal block after the leading end of the succeeding metal block is joined to a tail end 10B of the preceding metal block on the inlet side of a finish rolling mill 26, it is determined before and after joining whether or not endless rolling is impossible. When it is impossible, joining is aborted, and the succeeding metal block 12 is temporarily stopped, is fed again after the tail end 10B of the preceding metal block moves out of the finish rolling mill 26, and is finish-rolled under the conditions set for batch rolling. When joining was not performed successfully, a joint 11 is cut between a joining unit and the finish rolling mill 26, and the rolled material is bitten by the finish rolling mill set for batch rolling.

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.
