直接还原铁在限动芯棒钢冶炼中的生产实践

Production practice of applying DRI in steelmaking for retained mandrel steel

介绍了直接还原铁从普通钢试用到限动芯棒冶炼中的应用情况,结果表明直接还原铁适于在冶炼高质量钢时使用,并有优异的稀释有害元素,降低钢中氮含量并提高钢纯净度的作用。

This paper introduced the instance of applying DRI in steelmaking for retained mandrel steel, and achieved DRI was used in the steelmaking for the high quality steel products. Nay, DRI Could dilute harmful element, reduce nitrogen content and increase steel purity.
