Abstract: A system for cutting to length at least two strands of long rolled products (3, 5) preferably coming from a hot rolling mill. The system includes shears comprising at least two rotatable drums (4,6), each drum having a cutter (8,8?,10,10?) arranged to cut simultaneously at least two strands of long rolled products into finished segments. The system further includes at least two movable guides (12,14), each including at least two channels, each guide arranged to receive and guide at least one strand (3,5) of long product. The guides are movable between a position wherein, in operation, the strands of long product are located in positions either outside of the trajectory of the cutters in a position wherein the strands cannot be cut or wherein the strands are located on the trajectories of the cutters and can be cut by the cutters.

Abstract: A method for producing rolled products includes providing two parallel lines downstream of a continuous casting, for conveying profiled supply sections that converge together at least at a single first rolling station. A plant for implementing the method is also provided.

Abstract: An apparatus for producing elongated rolled products contains a steelmaking station for producing liquid metal having at a first production rate, a rolling mill having a second production rate, and a continuous casting station located between the steelmaking station and the rolling mill. The continuous casting station contains at least two casting lines, each line being operable to produce elongated intermediate products. A first casting line is directly aligned with the rolling mill to feed the rolling mill with casted products, and at least one second casting line not aligned with the rolling mill and not feeding the rolling mill. The apparatus further contains a varying device for varying simultaneously the production rate of the first casting line and the production rate of the at least one second casting line depending on a difference between the steelmaking station production rate and the rolling mill production rate.

Abstract: A stacker for the stacking of metallic section bars in alternating upright and reverse layers in an orderly manner, in particular of section bars originating from rolling mills by a conveying line which includes a plurality of trolleys equipped with lances capable of moving forward and backward from the reception area of a stack of section bars to a deposition area of the same layer of section bars in an upright position, and a plurality of magnetic heads capable of being actuated to rotate by a first set of actuating members from a picking-up position of another layer of section bars to a depositing position of the same layer of section bars reversed on top of the first layer of upright section bars.

Abstract: An automatic stacker with rotary heads for stacking in an ordered manner in alternate upright and inverted layers rolled metal sections originating from a rolling mill via a transport line is characterised in that each head also undergoes vertical translational movement in the directions of the arrow substantially parallel to itself, such movement being provided by a second drive mechanism independent of a first providing rotation of the head itself. In this manner, the head deposits softly and with precision each layer of sections on the layer placed below, thus avoiding jamming and improper stacking.

Abstract: A rotary electromagnetic head for automatic stackers of iron sections originating from a rolling mill. And an expulsion device is provided with a bar rotating together with the head but also provided with simultaneous movement relative to the head. This relative movement is caused by a cam against the action of a counteracting spring.
