进行了钢包底吹氮、底吹氮 -氩和底吹氩三种精炼工艺对比试验 ,结果显示 ,钢中氮含量对钢的拉拔性能影响显著 .钢的拉拔性能随钢中氮含量下降而有所改善
The comparative experiments of the three nitrogen blowing technologies, including bottom blowing of nitrogen, bottom blowing of nitrogen and argon, and bottom blowing of argon, were carried out. The results showed that the nitrogen content in steel had a significant influence on the drawing performance of steel. The drawing performance of steel decreased with the nitrogen content in steel And some improvement
