Abstract: Coiling method and device (“R”) for a long product (10). The device (“R”) comprises a mandrel (12) with a substantially cylindrical shape and rotating around its own axis, and a containing element (13) coaxial with the mandrel (12), rotating together therewith and defining a front wall (32) to contain the coil of product (10) to be formed. The containing element (13) comprises an annular channel (14) to clamp the leading end of the product (10) around the mandrel (12). The containing element (13) is mobile axially with respect to the mandrel (12) between a first position wherein the leading end of the product (10) is inserted, and a second position wherein the coil of product (10) is completed.

Abstract: A bar speed changing device (48) comprising a pair of upper rollers (55, 55?) and a pair of lower rollers (59, 59?). Said device receives a bar section with the rollers (55, 55?, 59, 59?) in the open position and rotating at a given speed. Upon leaving the device (48) said sections are fed into axially arranged peripheral seats (58) of rotating drum channels. Control devices calculate the speed at which the bar section must be released, upon completion of the braking action, according to the position that said section must occupy in one of said seats and on the basis of the bar-seat friction coefficient. When the rollers (55, 55?, 59, 59?) receive the bar, they turn at the calculated release speed. At a predefined moment, such to enable braking in the correct space and time, the four rollers close on the section and exert the braking action, exploiting the dynamic friction between the roller-section.

Abstract: A device for reeling semi-finished rolled products comprises two sections (1, 2) connected together to form an articulated arm that guides the product (BL) coming out of a rolling mill onto the reel that is being wound. The second section (2), which is closer to the reel, during winding, maintains its own inclination constantly equal to the inclination of the turns of the reel. This enables a considerable reduction of the gap between the adjacent turns and prevention of any overlapping (i.e., climbing on top of one another) between the turns already wound and the turns being distributed on the same layer. Reels that are more compact and have a more precise geometry are thus obtained. Also described is a device (12) for guiding the rolled product (BL) arriving on the reel with greater precision.

Abstract: Plant for packing bars after the rolling cycle comprising a feeding unit, a shear (45) for cutting the bar to size, a pair of deflector devices (46), (47) and a bar braking device. The bar segment deflector devices send the bar segments into seats (58) arranged along the perimeters of pairs of rotating cylinders (50), (51), (52), (53) and parallel to the axis of the cylinder, after making them pass through a bar braking device (48) to slow the bars down to the predefined speeds. The bars are unloaded from the seats onto conveyors (60), (61), (62), (63) and transported to a station where they are packed into bundles.

Abstract: Coil winding method for steel bars providing, at the outlet of the rolling mill (2), cooling stages by means of WB (4?, 4?, 4??) and equallsation in air so as to perform “soft” hardening on the bar which generates a microstructure consisting, on the surface, of martensite and bainite and, in the center, of ferrite and pearlite, and winding of the bar in the form of a compact coil by means of a coil winder (5). In the position wound on the coil, the bar cools slowly with tempering of the bainite and martensite formed on the surface. This is followed by a straightening stage, jo performed during the coil unwinding phase, and a natural ageing stage, maintaining the bar at ambient temperature.
