    Abstract: A method for producing long metal products includes the steps of receiving long intermediate products traveling on respective continuous casting lines, to an exit area, and subsequently introducing products from the exit area into a production plant having known layout parameters; the production plant has a rolling mill for rolling the products; interconnected production lines between the exit area of the casting machine and the rolling mill, the production lines define production paths or routes; and a first and a second heating devices. The method associates a mathematical model to the production plant for dynamically calculating a reference value, or Global Heating Cost Index, correlated to heating devices; automatically determining for the intermediate products the production path or route that minimizes the reference value, or Global Heating Cost Index; and eventually automatically routing each of the products along the determined production path which minimizes the reference value, or Global Heating Cost Index.

    Abstract: An apparatus changes rollers of a straightening machine. The straightening machine contains a plurality of cantilever roller shafts for receiving the rollers. The apparatus contains at least a trolley having a device for supporting an entire set of upper and/or lower rollers to be installed in or taken off from the straightening machine. The apparatus further has at least two vertical plates spaced apart horizontally, a device for releasably securing the plates to the trolley, and an actuator connected to the plates and intended to be received in first passages defined in the straightening machine. The actuator is able to reversibly displace the plates and the trolley between a first position wherein the plates and the trolley are close to the straightening machine and a second position wherein the plates and the trolley are spaced apart from the straightening machine.

    Abstract: A straightening machine includes a frame supporting housings in which each housing receives a roll shaft rotatable about its axis. At least one first assembly includes a first guide defining a first convex surface and a first corresponding guided element defining a first concave surface. The first surfaces contact each other at a first contact surface. At least one second assembly includes a second guide defining a second convex surface and a second corresponding guided element defining a second concave surface. The second surfaces contact each other at a second contact surface. A device for rotating at least one roll shaft housing carries out a rotation being guided by the assemblies about a virtual axis transverse to a roll shaft axis, to compensate bending due to straightening of a product.
