Problems solved by technology

This, combined with the inability to control how the coils are distributed across the surface of the spool, can lead to coils overlapping each other, which in turn can mess up the unwinding process

Embodiment Construction

[0025] Referring first to Figure 1, the storage 10 is arranged to receive 1 The incoming hot-rolled wire is conveyed along a conveying axis "A" and along a path "B" transverse to the axis A the rolled stock is conveyed to a downstream stand.

[0026] Referring additionally to FIGS. 2 to 5 , it can be seen that the accumulator 10 includes a drive shaft 14 supported for rotation about axis A between bearings. One end of the drive shaft is coupled to an output shaft 20 of a gearbox 16 which in turn is driven by an electric motor 18 .

[0027] As best seen in FIG. 4 , the other end of the drive shaft 14 is constructed and arranged to support a curved laying assembly LA comprising a laying tube 22 and a helical channel extension 24 .

[0028] The laying pipe has an inlet end 22a aligned with the axis A to receive the hot rolled stock, and a curved intermediate section leading to an outlet end 22b in communication with the inlet end 24a of the helical channel. The outlet end 24b o...

Abstract

A method is disclosed for continuously rolling a product exiting from an upstream roll stand RSl at a delivery velocity Vl higher than the take in velocity V3 of a downstream roll stand RS2. The excess product resulting from the velocity differential between Vl and V3 is temporarily accumulated between the roll stands.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Serial No. 11 / 375,448, filed March 14, 2006. technical field [0003] The present invention relates generally to rolling mills for the production of hot-rolled long products such as bars and wire, and in particular to methods for continuously rolling the products in successive upstream and downstream rolling stands, wherein The rolling stock is delivered from the upstream rolling stand at a speed higher than the bite speed of the downstream rolling stand. Background technique [0004] In a typical rolling mill installation, the billet is heated to an elevated rolling temperature in a furnace. Then the heated billet is successively rolled through the rough rolling zone, the intermediate rolling zone and the finishing rolling zone of the rolling mill, and each rolling zone includes a plurality of rolling stands. For large-scale products, the entire rolling mill can usually...
