摘　　要：介绍电弧焊用焊条钢H08A的试制过程。通过对钢水脱氧工艺的研究,解决了连铸坯严重的皮下气泡,同时保证钢水良好浇铸性;采用低温吐丝轧制工艺,提高断面收缩率,降低表面氧化铁皮含量,改善了生产过程吐丝乱圈。To introduce trial production process of H08A wire rod for arc welding.Through research of deoxidization process of molten steel,the problem of subcutaneous bubbles in continuous casting billet is solved,and the good castability of molten steel is ensured at the same time.Adopting low-temperature wire laying rolling process,the reduction of area is increased,the content of iron oxide scale on surface is reduced,and the phenomenon of disordered wire laying in production process is improved.

关 键 词：H08A 盘条 电弧焊 氧化铁皮 吐丝温度 断面收缩率
