| titleOfInvention | Method of making regular grain oriented silicon steel without a hot band anneal |
| abstract | A process of producing regular grain oriented silicon steel having a final thickness of from 7 mils (0.18 mm) to about 18 mils (0.45 mm) including the steps of providing a silicon steel hot band, removing hot band scale, cold rolling to intermediate gauge without an anneal of the hot band, performing an intermediate anneal at a soak temperature of about 1650° F (900° C) to about 1700° F (930° C), subjecting said annealed silicon steel to a first stage slow cooling at a rate of about 500° F (260° C) to about 1050° F (585° C) per minute down to about 1100° F ± 50° F (595° C ± 30° C), thereafter subjecting said silicon steel to a second stage fast cooling down to from about 600° F (315° C) to about 1000° F (540° C) at a cooling rate of from about 2500° F (1390° C) to about 3500° F (1945° C) per minute followed by a water quench, cold rolling to final gauge, decarburizing, applying an annealing separator and final annealing. |
