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.
Claims20
A method of threading a metal substrate on a rolling mill comprising:
- receiving a coil of the metal substrate, wherein the coil of the metal substrate comprises a foil layer between adjacent layers of the metal substrate within the coil;
- uncoiling the metal substrate from the coil;
- and
- guiding the metal substrate to a work stand of the rolling mill with a threading system,
- wherein uncoiling the metal substrate from the coil comprises separating the foil layer from the metal substrate before guiding the metal substrate to the work stand.
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;
- and
- quenching the metal substrate with at least one quench sprayer while guiding the metal substrate to the work stand.
A system for threading a metal substrate on a rolling mill comprising:
- a threading carriage comprising a gripper configured to grip a metal substrate;
- a track extending between an unwind mandrel and a work stand of the rolling mill;
- and
- at least one quenching station between the unwind mandrel and the work stand,
- wherein the threading carriage is movable along the track,
- wherein the threading carriage is configured to guide and apply tension to the metal substrate between the unwind mandrel and the work stand, and
- wherein the at least one quenching station is configured to quench the metal substrate between the unwind mandrel and the work stand.
