Abstract
Systems and methods of threading a metal substrate on a rolling mill include receiving a coil of the metal substrate. The method also includes uncoiling the metal substrate from the coil while the coil and guiding the metal substrate to a work stand of the rolling mill with a threading system.
Claims8
A method of threading a metal substrate on a rolling mill comprising:
- receiving a coil of the metal substrate;
- uncoiling the metal substrate from the coil;
- guiding the metal substrate to a work stand of the rolling mill with a threading system, wherein guiding the metal substrate to the work stand comprises:
- guiding the metal substrate to a threading carriage of the threading system;
- gripping the metal substrate with the threading carriage;
- and
- moving the threading carriage towards the work stand,
- wherein the threading carriage comprises a gripping wedge, and wherein gripping the metal substrate with the threading carriage comprises directing the metal substrate through the gripping wedge and closing the gripping wedge on the metal substrate at a position that is offset from a leading edge of the metal substrate to grip the metal substrate, and
- wherein the method further comprises adding stiffness to the metal substrate by closing the gripping wedge and crimping the metal substrate with the gripping wedge such that the metal substrate comprises at least one lateral curvature across a width of the metal substrate.
6 more elements
A system for threading a metal substrate on a rolling mill comprising:
- a threading carriage comprising a gripper configured to grip a metal substrate;
- and
- a track extending between an unwind mandrel and a work stand of the rolling mill,
- wherein the threading carriage is movable along the track, and wherein the threading carriage is configured to guide and apply tension to the metal substrate between the unwind mandrel and the work stand,
- wherein the gripper comprises a gripping wedge configured to close on the metal substrate at a position that is offset from a leading edge of the metal substrate, and
- wherein the gripping wedge is further configured to crimp the metal substrate such that the metal substrate comprises at least one lateral curvature across a width of the metal substrate.
