摘要： An annealing separator for manufacturing grain-oriented silicon steel with mirror-like surface having good magnetic performance consists of the composition of which is 77-98 by wt% of Al 2 O 3 powder, 1-8 by wt% of alkaline earth powder, 1ˆ¼15 by wt% of alkali metal chloride and/or alkaline earth metal chloride. The annealing separator of the invention can avoid forming a glass-film undercoating on the surface of the steel sheet during high-temperature annealing, and at the same time, the oxide embedded at near-surface of the sheet is removed by means of corrosive reaction of the chloride, so that a produce with smooth surface and stable magnetic performance is obtained.

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.
