0.50~0. 15Si)of scmi-process non-oriented electrical steel with coating are produced by hot metal pretreatment-top and bottom combined blowing converter-RH-CC-hot rolling-cold rolling-annealing process at Baosteel.Effect of annealing temperature at 550~900 ℃ on HV1 hardness value of the non-oriented electrical steel and effect of stress-relief annealing at 680~800 ℃ on magnetic properties of the steel were tested. For the finished semi-process non-oriented electrical steel products with coating annealed at 650~700 ℃
the core losses of designation B50A700T and designation B50A1300T stress-annealed at 750 ℃ for 2 h were 4.10 W/kg and 4.70 W/kg respectively.
