Provided are methods that can prevent either or both of kinking and collapsing of a steel sheet coiled in coil form regardless of the characteristics of the steel sheet. A method of determining a tension pattern of tension applied to a steel sheet to coil the steel sheet in coil form comprises calculating the tension pattern using an apparent elastic modulus in a radial direction of a coil.

A container includes an outer box, and a polygonal liner located within the outer box. The polygonal liner has a plurality of vertical walls. A continuous length of wire is located within the polygonal liner and forms a plurality of layers. Each of the layers is comprised of a series of wire loops arrayed polygonally along the vertical walls of the polygonal liner.

Disclosed within are various embodiments that provide for an automated rod coil cutting station for both ferrous and non-ferrous wire rod mills.

A combined iris and shear unit for a coil forming device is provided that includes an actuator and a plurality of support members coupled together in series to support formation of a coil and connected to the actuator. Each support member further comprises a retractable shear blade. The actuator adapted to cause movement of the support members between an open position with the blades of the combined iris and shear unit being retracted away from the reform tub wall, so that coil forming takes place within the reform tub without interference. A support position with the blades extends into the reform tub and providing support for the coil; or a shear position for cutting the coil before it is extracted.

A laying head for forming an axially moving hot rolled product into a helical series of rings includes a quill rotatable about an axis, with a tubular body journaled for rotation between axially spaced bearings, and a nose projecting axially and forwardly from its tubular body. A product guide is carried by the quill. The product guide is configured to form the product into a helical series of rings. A guide trough provides a helical extension of the product guide. Major portions of the product guide and the guide trough are carried on a continuous helical support on the nose of the quill. The guide trough is channel shaped, with a continuous bottom defining the rim of the helical support, and with segmented detachable side walls.
