Abstract
Large slabs are processed into memory free strip or plate. The large slabs are rolled into strip or plate on a rolling mill with a finishing temperature of above 1340.degree. F. The strip or plate is cooled inline to a temperature in the range of 900.degree.-650.degree. F. with the strip or plate laid out on a flat cooling conveyor. The speed of the strip or plate is slowed to speeds typical of cut-to-length lines. The strip or plate is side trimmed and cut to length and the strip or plate is subsequently stacked.
Claims10
A method of processing large slabs into memory free strip or plate comprising the steps of:
- a) rolling the large slabs into strip or plate on a rolling mill with a finishing temperature above 1340.degree. F.;
- b) coiling the strip or plate at a temperature above 1340.degree. F.;
- c) transferring the coiled strip or plate to an in-line cooling and cut-to-length line and uncoiling at temperatures above 1340.degree. F. at speeds below 150 feet per minute;
- d) in-line cooling the strip or plate to a temperature below 900.degree. F. with the strip or plate laid out on a flat cooling conveyor;
- e) side trimming and/or cutting the strip or plate to lengths;
- and
- f) stacking the strip or plate.

- a) rolling the large slabs into strip or plate on a rolling mill with a finishing temperature above 1340.degree. F.;
- b) slowing the speed of the strip or plate to speeds typical of cut-to-length lines on a rollout table long enough to accept the entire strip or plate without being cut;
- c) in-line cooling the strip or plate to a temperature below 900.degree. F. with the strip or plate laid out on a flat cooling conveyor;
- d) side trimming and/or cutting the strip or plate to lengths;
- and e) stacking the strip or plate.
