摘要： A non-oriented electrical steel having excellent magnetic properties, the chemical elements thereof in percentage by mass being: Si: 0.2-1.5%, Mn: 0.01-0.30%, Al: 0.001-0.009%, O: 0.005-0.02%, C≤0.005%, S≤0.005%, N≤0.005%, and Ti≤0.002%, the remainder being Fe and other unavoidable impurities, and Al/Si≤0.006 and Mn/Si≤0.2. The method for producing comprises the following sequence of steps: (1) smelting; (2) hot rolling: the slab heating temperature being 850°C to 1250°C, and the final rolling temperature being 800-1050°C; (3) acid pickling; (4) cold rolling; (5) annealing: the annealing plate temperature being controlled between 620°C-900°C; and (6) coating.

摘要： The present invention refers to a chromium-free insulation coating material for non-oriented silicon steel, comprising, by mass shares, the following components: metal dihydrogen phosphate salt of 100 shares, epoxy resin of 10~60 shares, naphthenate drier or isooctanoate metal salt drier of 0.001~10 shares, organic solvent of 0.001~100 shares and pure water of 60~2000 shares. The metal dihydrogen phosphate salt is Al(H 2 PO 4 )3, Mg(H 2 PO 4 ) 2 , Ca(H 2 PO 4 ) 2 or Zn(H 2 PO 4 ) 2 ; the epoxy resin is water- soluble epoxy resin or epoxy resin emulsion. Chromium-free insulation coating material of the present invention, after being coated on non-oriented silicon steel, renders highly transparent appearance, and has excellent insulativity, corrosion resistance, adhesiveness, weldability and manufacturability, so as to eliminate defects of the existing chromium-free coating, such as sticky and un-wear-resistant and to meet environment protection requirements.
