Patent ID: 11931784

Abstract:
A rolling mill for solid elongated products, defining a rolling axis, including first and second rolling stations. Each station includes a load-bearing structure, a removable roll-holder cartridge with three rolling rolls movable radially and rotating around spaced rotational axes, and a roll having a vertical rotational axis. A system synchronizes mechanical adjustment of the rolls. Three actuators mount on the load-bearing structure; three gear motor groups connect to the rolls by single extensions. The second station rolls are rotated 60° from the first stations. The rolls with a vertical axis of the first and second stations are arranged on opposite sides of the rolling axis. All rolling stations allow lateral extraction of roll-holder cartridges from the same side of the rolling mill. The stations on the extraction side have actuators movable relative to the load-bearing structure. The stations with vertical rolls arranged on the opposite side have fixed actuators.
