US Patent 7736444 Method and system for manufacturing electrical silicon steel

Grain oriented electrical steel is made in a manner that the grains are selectively grown to obtain a crystal structure known as cube-on-edge and the grains are largely aligned in the rolling direction. Selection of chemistry and process route along with thin slab continuous casting enables the production of Grain oriented electrical steel such that less energy is consumed in the process, certain process steps can be combined, yield is better and the product can be manufactured within a wider process control tolerance.
