An improved sliding chain-type ingot mold for a continuous casting plant, including two pairs of chains arranged in a closed ring system and configured to rotate in opposite directions, each pair including at least one of molding elements and shell-type elements which forms a closed mold, the two pairs of chains being arranged to wind up on respective sprockets, one pair having a first set of the at least one of molding elements and shell-type elements configured to interlock with a second set of the at least one of molding elements and shell-type elements on the other pair to form a cavity for receiving a molten material, external pressurizing rollers configured to act on the first and second sets of the plurality of at least one of molding elements and shell-type elements to detach and approach with each other, and fixed contrasting elements fixedly positioned to counteract the pressurizing rollers.

Sliding chain-type ingot mold for a continuous casting plant

In a sliding chain-type ingot mold (,), each mold is constituted by molding elements (,) representing two half-molds which can be made to face each other so as to form a closed mold shaping a cavity to hold the molten metal. According to the invention, some engaging elements (,) are provided, capable of interacting with cam-shaped surfaces (,) provided on one side on at least one (,) of said molding elements, and on the other side on a fixed frame (,) designed to detach and approach said molding elements.

A bar deburring plant for cut to size round bars, comprising: a first roller feed path of cut bars towards an alignment element of one first end of said bars, a first transfer element of said bars, with said first aligned end, to a conveyor of said bars, which are spaced one after the other, said conveyor carries said first ends of said aligned bars under a brushing head, a second roller feed path of said cut bars going towards a second alignment element of the second end of said bars, a second transfer element of said bars, with said second aligned end, to a second conveyor of said bars, which are spaced one after the other, said conveyor carries said second ends of said aligned bars under a second brushing head.

Bar deburring plant

A rolling cage to produce hot rolled bars, comprising at least one pair of rolling cylinders (12, 13) mounted on their respective stands (14, 15) in which a clearance (17) (processing gap) between said cylinders (12, 13) is adjusted by a system of screws (18) and lead screws (21), and which provides for a hydraulic pre-loading system of the same cylinders (12, 13) after adjusting the said clearance (17). According to the invention, the pre-loading system of said hydraulic cylinders (12, 13) comprises a multiple number of rods (27) crossing said stands (14, 15) and capable of a relative sliding motion. Each of said rods (27) is at one extremity (28) attached to a stand (14) while the opposite extremity is equipped with a piston (29) moving inside a hydraulic cylinder (30) firmly attached to the stand (15) opposite the former, so that said rods (27) also serve the function of opposing the rolling torque.

Hydraulically preloaded rolling stands

A sizing stand (10) for rolling hot-rolled bars (17) comprises at least one pair of rolling rolls (13) carried by chocks (12) mounted on a support frame (11). Said stand also comprises power means (14) able to compression-preload the rolling system with a load greater than the maximum working load.

Sizing stand for rolling hot-rolled bars

A facility for in-line heat treatment of hot-rolled products, for example, long rods (16) includes: a tank (11) suitable for containing a refrigerating liquid medium (12), a plate (13) with stationary rakes (14) and mobile rakes (15) suitable for receiving the products (16) and transporting them through the tank (11) and outside of it on heat treatment performed, and closure lids (27) arranged above the plate (13).

Facility for in-line heat treatment of hot-rolled products

A rolling stand with tie-rods, having extremely high strength to axial stresses, which includes a stand base supporting at least two rolling rolls supported by carriers which can be vertically moved in order to be approached or moved away from each other by means of four vertical tie-rods having screw-threaded portions. The screw-threaded portions are provided on opposite sides of at least one pair of support feet arranged between the stand base and the carriers which support and contain a central smooth portion of the tie-rods. A contoured portion extends from at least one of the support feet upwards and downwards in a parallel direction to the tie-rods. The contoured portion houses and guides a vertical rib protruding outwards from the carriers. Both contoured portion and the vertical rib engage, on mutually opposite surfaces, freely removable adjustment/sliding elements.
