介绍了鞍钢260 t转炉应用铁碳球的工艺实践。通过采取优化铁碳球加料方式、加入时机、氧枪操作及转炉底吹流量等措施，增加了铁碳球的使用量，降低了溢渣比率，烟尘外溢现象减轻，对转炉终点氮含量影响不大。

The process practice of iron-carbon balls applied by the 260 t converter in Angang is introduced. By taking such measures as optimizing charging mode, adding time of iron-carbon balls, the operation of lance and nitrogen flow rate of the converter bottom blowing, the usage of iron-carbon balls is increased, the ratio of excessive slag cut down, the overflow of dust and fume reduced, all of which has less effect on the end point content of nitrogen in molten steel by bottom blowing converter.
