摘　　要：根据客户特殊需求开发了压力容器用埋弧焊丝钢H10Mn2-A盘条,为了保证低倍组织质量,通过LF精炼进行窄成分和气体含量控制,连铸全程保护浇注,过热度≤30℃,拉速2.2 m/min。为了获得优良的成品力学性能,采用控轧控冷工艺,开轧温度1000±20℃,吐丝温度890±10℃,辊道速度15 m/min。经客户试用,H10Mn2-A盘条强度适中、塑性好,易拉拔,冲击韧性良好,满足压力容器用焊丝的拉拔和焊接性能要求。Submerged arc welding wire steel H10Mn2-A wire rod for pressure vessels was developed according to the special requirements of customers.In order to ensure low tissue quality,narrow composition and gas content were controlled by LF refining,and the casting was protected throughout continuous casting.The superheat was less than 30℃and the pulling speed was 2.2 m/min.In order to obtain excellent mechanical properties of finished products,controlled rolling and controlled cooling process was adopted.The opening rolling temperature was 1000±20℃,the spinning temperature was 890±10℃,and the roller table speed was 15 m/min.After customer trial,H10Mn2-A wire rod moderate strength,good plasticity,easy to draw,good impact toughness,to meet the pressure vessel welding wire drawing and welding performance requirements.
