摘　　要：选取青岛特钢生产的焊接用钢盘条H08Mn、EH12K等进行试验。试验结果表明:随着盘条中Si元素含量的增高,焊接用钢盘条表面的氧化铁皮厚度逐渐减薄;当Si含量达到0.35%时,盘条基体表面开始形成不规则的FeO/Fe2SiO4相,Si含量达到0.60%后,氧化皮/基体界面凹凸化严重,界面绝对长度增加,盘条氧化铁皮的去除难度增大。The steel wire rods H08Mn and EH12K for welding produced by Qingdao Special Steel were tested.The test results show that with the increase of the Si element content in the wire rod,the thickness of the iron oxide scale on the surface of the steel wire rod for welding gradually decreases.When the Si content reaches 0.35%,the surface of the wire rod matrix begins to form irregular FeO/Fe_(2)SiO_(4) phases.After the Si content reaches 0.60%,the oxide scale/substrate interface becomes severely uneven,the absolute length of the interface increases,and the removal of the wire rod oxide scale becomes more difficult.
