在50Kg氧化镁坩埚真空感应炉上进行高硅电工钢的脱氧试验。结果表明,通过控制原料的成分、高真空下的碳氧反应和炉衬分解向钢液中的供氧,可使钢液的总氧含量≤15×10-6;在维持高温高真空条件下,当钢液中的反应达到一定程度后,延长精炼时间并不能降低钢液的总氧含量;完成精炼后加入硅钙合金沉淀脱氧可进一步降低钢液的总含氧量,但脱氧效果有限。 The test of high-silicon electric steel deoxidation has been carried out in 50Kg vacuum induction furnace with magnesium oxide crucible.Results show that the total oxygen could be ≤15×10-6in molten steel by controlling material components,carbon-oxygen reaction in high vacuum and oxygen contamination from crucible materials on molten steel;And when the reaction was carried through to a certain extent,total oxygen in molten steel could not be reduced by the extension of refining period in high va... 

电工钢反复弯曲次数是电工钢性能检验的重要指标之一,直接影响到用户在使用电工钢过程的机加工性能。主要分析了试样宽度、试样张力、晶粒取向、反复弯曲设备等因素对电工钢反复弯曲试验的影响,并对各个因素的影响程度进行量化以及原因探讨,从而归纳形成各影响因素的基本规律,以便为电工钢实际生产、用户使用提供科学指导。结果表明:试样宽度增加,反复弯曲次数也会不断增加,晶粒位向对取向电工钢的反复弯曲次数影响较大,当支座顶部到拨杆底部的距离减小或拉紧力增加时,反复弯曲次数会不断减小,但当拉紧力达到60N以上时,对反复弯曲次数影响不大,试样经退火后,反复弯曲次数略有上升。 The reverse bend number is an important performance of electrical steels′capabilities,affecting the machining performance directly when the customers used.It investigated some factors,such as sample′s width,sample′s tension load,grain orientation and equipment,how to effect the reverse bend test for electrical steel,measured the influence degree,and discussed the reason,in order to form basic rules which could be guided the manufacturing and using for electrical steel.Results showed that the rev...
