Abstract
A method of processing large slabs into memory free strip or plate comprises the steps of: rolling the large slabs into strip or plate on a rolling mill with a finishing temperature above 1340.degree. F.; in-line cooling the strip or plate to a temperature in the range 900.degree. F. to 650.degree. F. with the strip or plate laid out on a flat cooling conveyor; slowing the speed of the strip or plate to speeds typical of cut-to-length lines; side trimming and/or cutting the strip or plate to lengths at temperatures above 500.degree. F.; cooling the strip or plate to a temperature below 300.degree. F.; and stacking the strip or plate.

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) in-line cooling the strip or plate to a temperature in the range 900.degree. F. to 650.degree. F. with the strip or plate laid out on a flat cooling conveyor;
- c) slowing the speed of the strip or plate to speeds typical of cut-to-length lines;
- d) side trimming and/or cutting the strip or plate to lengths at temperatures above 500.degree. F.;
- e) cooling the strip or plate to a temperature below 300.degree. F.;
- and
- f) stacking the strip or plate.
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 in the range 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 at temperatures above 500.degree. F.;
- f) cooling the strip or plate to a temperature below 300.degree. F.;
- and
- g) stacking the strip or plate.
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) slowing the speed of the strip or plate to speeds below 150 feet per minute 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 in the range 900.degree. F. to 650.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 at temperatures above 500.degree. F.;
- e) in-line cooling the strip or plate to a temperature below 300.degree. F.;
- and
- f) stacking the strip or plate.
