A process for the preparation of a thin strip of high silicated steel as well as produced according to the strip and the iron core for electrical devices

摘要

A high silicon steel strip having excellent magnetic properties and good workability, and having a composition consisting of 4-10% by weight of silicon and the remainder being substantially iron and incidental impurities is produced by cooling super rapidly the high silicon steel melt on a cooling substrate to form a thin strip having micro-structure comprising very fine crystal grains having substantially no ordered lattice.
