Abstract: In order to meet energy conservation, consumption reduction and high quality, the full-processed non-oriented electrical steel 50W800 was successfully developed and produced in batch by a production flow of BOF steel-making, RH degassing, ladle furnace (LF) refining, compact strip production (CSP) line, cold rolling and continuous annealing. By testing, the magnetic properties of 50W800 are excellent:the iron-loss (P_1.5/50 is less than 4.6 W·kg^-1, the magnetic induction (B₅₀) is more than 1.71 T, the flatness and surface quality of products are fine, and the coating has the satisfied properties of insulation and corrosion resistance. The products are suitable for the motor manufacture industry.
