对1990~2010年在我国申请的冷轧无取向硅钢涂层的专利数量、专利技术领域分布进行了统计,对典型涂层专利技术进行了分析,探讨了无取向硅钢涂层的发展趋势。统计分析结果表明,目前无取向硅钢涂层典型的专利技术主要有自粘结涂层、无铬含稀土元素涂层、含钼酸盐环保涂层及采用有机-无机纳米杂化材料为主成膜物形成的涂层等。无取向硅钢涂层发展的趋势主要是无铬环保的半无机、半有机型涂层。 The patent quantity of cold-rolled non-oriented silicon steel coating and distribution of technology fields applied in China in 1990-2010 were summarized.The analysis results indicate that typical patent technologies include self-adhesion coating,chromium-free and with rare earth element coating,environment-friendly and with molybdate coating,coatings with organic-inorganic hybrid materials as main forming agent and so on.The main development trends of coatings on silicon steel are among semi-in... 

冷轧无取向硅钢（/%:0.003C,2.35Si,0.22Mn,0.011P,0.002S,0.36A1,0.003 0N）经890℃或940℃3 min常化的2.3 mm热轧板冷轧成0.35 mm薄板。研究了常化温度和800⁹20℃3 min退火对该钢高频（400Hz）磁性能和抗拉强度的影响。结果表明,830⁹20℃退火时高频铁损P_10/400值最低,随退火温度增加,晶粒尺寸增大,钢的抗拉强度降低;该钢的最佳热处理工艺为常化温度940℃,退火温度830℃,其抗拉强度R_m、高频铁损P_10/400和磁感应强度J₅₀分别为565 MPa,21.5 W/kg和1.69 T。 The cold-rolled non-oriented silicon steel（/%:0.003C,2.35Si,0.22Mn,0.011P,0.002S,0.36A1,0.003 0N） is cold-rolled to 0.35 mm sheet from 2.3 mm hot-rolled plate normalized at 890 ℃ or 940℃ for 3 min.The effect of normalizing temperature and annealing process at 800 ⁹20 °C for 3 min on high frequency（400 Hz） magnetic properties and tensile strength of the steel has been tested and studied.Results show that with annealing at 830 920 ℃the high frequency iron loss value P_10...
