Production of electrical steels

Abstract

Current production methods of electrical steels follow the process routes used in typical steel sheet product process, starting with the production of the liquid steel from either the basic oxygen steelmaking process (BOS) using liquid iron produced in blast furnaces as the main constituent, or electric arc steel making where the main constituent is steel scrap produced by recycling. There is no particular advantage for electrical steels in using either route. This chapter considers the production methods of electrical steels and the effects of each method on the final composition and crystal structure and microstructure.
