Main technology parameters of four developed process: cast bloom higher temperature heating-double cold rolling or single cold rolling

lower temperature heating-double cold rolling or single rolling process for production of common grain oriented silicon steel (CGO) and high magnetic induction grain oriented silicon steel (Hi-B)

theory research on grain oriented steel ( Goss nucleus and inhibitor) and present situation of process are summarized in this paper. The development trend of grain oriented silicon steel is increasing (110) [001 ] grain oriented degree

decreasing iron loss of grain oriented silicon steel

developing cast bloom lower temperature heating ( ≤1300 ℃) and thin slab concasting and continuous rolling flow sheet to produce grain oriented silicon steel.
