Abstract

Newly developed processing routines on U. S. Steel’s Hot Dip Process Simulator (HDPS) have enabled accurate simulation of the operating characteristics of a continuous electrical sheet processing line.  The two key components of the electrical steel production process simulated were decarburization and grain growth.  As the HDPS cannot process panels of a size adequate for obtaining longitudinal and transverse mini-frame (16.5 cm long) Epstein packs, new coupon test techniques for magnetic property measurement were required.  Magnetic properties measured on coupons tested in a small single sheet tester were correlated to those measured on full size (30.5 cm long) Epstein packs.  Reasonable agreement between the Epstein and coupon properties was achieved.  Magnetic properties obtained via laboratory processing and testing have agreed with those from mill processing and testing.  The HDPS electrical steel simulations are now being used to more fully explore the processing-microstructure-property interrelationships in continuously annealed electrical steels.
