摘要： 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.
