Abstract

An apparatus for actively transferring a coil of hot metal within a coilbox in hot strip mill. The apparatus is located downstream of the initial coilbox uncoiling station and includes at least one singly pivoting coil cradle. Such a coil cradle has a first support roller with a fixed rotational axis, a swing-frame mounted to pivot about that axis, and a second support roller mounted to the swing-frame, able to pivot about the fixed rotational axis of the first support roller to permit the coil of hot metal to be passed from the coil cradle. In certain embodiments, the apparatus includes a plurality of such singly pivoting coil cradles. The apparatus may also include at least one dually pivoting coil cradle.

Description

technical field [0001] The invention relates to an apparatus for handling coils of metallic material in a hot strip mill production line. More specifically, the present invention relates to an apparatus for actively conveying a hot metal coil in a coil box downstream of an initial uncoiling station. Background technique [0002] Coil boxes provide an intermediate process in hot strip mills where hot metal conveyor bars (bar) are coiled at high speed from the roughing mill and uncoiled at low speed into the finishing mill. The head of the conveyor strip enters the coil box and is guided into the coiling area where bending rollers drive and create a downward bend, first forming the coil eye, It then assists in forming additional coil wraps around the holes. A coil forming roller and a pair of driven cradle rollers support and contain the growing coil. [0003] The unwinding process begins when the carrier roller reverses the rotation of the web and the force of the peeler o...
