摘要： A non-oriented electrical steel sheet with fine magnetic performance, and a calcium treatment method therefor, including an RH (Ruhrstahl-Heraeus) refinement step. The RH refinement step sequentially comprises a decarbonization step, an aluminum deoxidation step, and a step of adding calcium alloy. In the step of adding calcium alloy, time when the calcium alloy is added satisfies the following condition: time interval between Al and Ca/total time after ΣAl=0.2-0.8. In this method, production cost is reduced, the production process is simple, a normal processing cycle of RH refinement is not affected, the device is convenient in operation and is controllable, and foreign substances are controllable in both shape and quantities. The non-oriented electrical steel sheet prepared according to the present invention has fine magnetic performance, and the method can be used for mass production of the non-oriented electrical steel sheet with fine magnetic performance.
