摘要： The present invention relates to a device for guiding a movable element, in particular a driving bar of a mandrel or a mandrel, in a rolling mill with mandrel. The device according to the invention comprises a support structure for the advancement of the movable element along an advancement direction. The device comprises a first slide and a second slide which are carried by said support structure and are slidable along a transverse direction which is substantially orthogonal to said advancement direction, in which each slide carries two abutment surfaces for guiding the movable element and in which each slide is movable along said transverse direction between at least a first operating position, upon reaching which said abutment surfaces are susceptible to coming into contact with a movable element of a first predefined diameter, and at least a second operating position, upon reaching which said abutment surfaces are susceptible to coming into contact with a movable element of a second predefined diameter. According to the invention, the device comprises actuating means which move the slides along the transverse direction between the operating positions and lock the slides themselves when one of said operating positions is reached.

摘要： A delivery device for delivering stock material into a blast furnace includes a transition channel for the stock material, a chute for delivering the stock material, a first annular body, coaxial to and outside the transition channel, adapted to rotate about a first axis, and a second annular body, coaxial to and outside the first annular body, adapted to translate along the first axis with respect to said first annular body and/or to rotate about the first axis together with said first annular body. When the second body translates along the first axis, at least one fixed rack rotates at least one toothed wheel and a respective shaft about a second axis transversal to the first axis, thus causing a change in the inclination of the chute with respect to the first axis.
