A continuous rolling mill for producing seamless tubes, operating on the restrained mandrel principle, has a stand-less structure which includes a load-bearing box-type framework wherein there are formed seats for accommodating working rolls and their chocks. The structure has reduced bulk in the axial direction and weight.

Load-bearing structure for a continuous rolling mill for seamless tube

A mandrel-carrier head for fixed-mandrel continuous rolling mill has a horizontal hook portion engageable with the tail of the mandrel. This portion has a U-section in the direction of the rolling axis. One of the limbs or a part thereof is movable towards and away from the other limb, so as to lock the tail of the mandrel previously positioned between the limbs.
