| 摘 要： | SN490B H型钢是日本开发的抗震建筑专用钢材,日本用户对该钢种的成品成分要求严格,最初生产的产品成分和性能不能满足用户的要求。莱钢根据日标SN490B建筑结构用H型钢主要技术经济指标要求,对炼钢工序主要化学成分波动的原因进行了分析,制定了适当调整成分和减少炼钢工序增碳措施,改进后SN490B H型钢成品成分控制和力学性能稳定性大幅提高,满足了日本客户的要求。

| Abstract: | The reason of chemical component in steel making being unstable is analyzed. Some measures are adopted： properly adjust the component, eliminate some carbon-increasing measures. And after that the stability of component control and mechanical property of H-section steel SN490B got obviously improved, and can meet the demand from Japanese costumers. |
