Abstract: A plant for the production and packaging of bars and steel profiles includes a rolling station of rods and profiles of indefinite length, a cooling station, a scrap separation station, a diverter device, cutting shears, intended to cut said bars and profiles in bar portions having a fixed length, and a speed changing device, able to move the bar portions at a speed rate such that they can be placed within respective grooves or housing provided on the outer surface of at least one cylinder or rotating drum. Each cylinder or rotating drum is associated with a speed changing device, so that the housing receives bar portions at different speeds, depending on the fact that the housing belong to one first or to at least second rotating cylinder, in order to avoid overlap of the bar portions when the same are discharged onto the cooling plate.

Abstract: The present invention relates to a energy-saving steel production apparatus, including an hot-rolling production line and a continuous casting equipment (5) for producing semi-manufactured products or billets (10), said production line and said equipment facing one each other and being connected through fast transport means (7) moving said billets (10). The invention also relates to a method for processing energy-saving steel, comprising the following steps: a. taking the steel to a casting temperature; b. casting said steel in suitable moulds for obtaining a semi-manufactured product (10); c. transferring directly said casted semi-manufactured product (10) towards a rolling mill through fast transport means; d. taking said semi-manufactured product (10) to a value of temperature corresponding to a maximum value of plasticity; e. subjecting said semi-manufactured product (10) to a rolling process.

Abstract: Device for receiving and discharging bars fed forward in a longitudinal direction, preferably from a rolling mill and after being cut to length, of the type with two pair of adjacent, counter-rotating rollers/drums, characterized by the fact that the said bars are sent alternately into a zone immediately above each pair of said drums, which rotate and drag the bar between them in a downwards direction, and which subject the bar to elastic, friction compression in order to slow it down while it is being fed forward and then, continuing their rotation, make the bar fall in a pick-up zone below.

Abstract: A universal rolling mill stand of a demountable type having two pairs of adjustable rollers. One of the adjustable rollers has a pair of horizontal rollers and another has a pair of vertical rollers. The horizontal rollers and the vertical rollers are mounted demountably from a support base by a horizontal ring stand which is demountable from the base. A pair of lateral vertical side support structures slide apart in opposite directions from the pair of horizontal rollers such that an interior ring of a support roller bearing is retained on the rollers.

Abstract: A demountable rolling stand having a support base, a pair of rolling cylinders with necks formed thereon, two side structures for supporting the rolling cylinders laterally therebetween, at least two pairs of pretensioning tie-rods engaging the side structures so as to clamp the side structures to the cylinders. The side structures have cylindrical support roll bearings affixed thereto in support of the rolling cylinders. The necks of the rolling cylinders have an interior ring of the cylindrical support roll bearings affixed directly thereto such that the interior ring is removable along with the rolling cylinders. The support base is connected to the side structures so as to support the cylinders above a surface. The pretensioning tie-rods serve to pretension a rolling force between the cylinders.

Abstract: A bars packer plant having hung transfer magnets for packing bar layers differentiated in number including a single linear system of rotating hung transfer magnets movable between a position above a supply line with bar layers to be picked up to a position above a pack formation pocket. The transfer magnets rotate by turning upside down. A lifter is provided below the supply line and below the hung transfer magnets in a pick-up area. The lifter serves to lift one bar layer and attach it to a magnetic pickup surface above and below the hung transfer magnets, depending on the rotation of the magnetic pickup surface.
