在线常化工艺在Q345E无缝钢管生产中的应用

Applications of On-line Normalizing in Production of Q345E Seamless Steel Pipes

根据包钢无缝厂Φ400 mm机组现有的设备、工艺条件,通过采用在线常化控轧工艺,成功生产出低温高韧性的Q345E钢种输送流体用无缝钢管。

With the present equipment and technological conditions of Φ400 mm assembling unit in Seamless Tube Plant,the Q345E seamless steel pipes with high low-temperature toughness used for conveying fluid are produced by adopting on-line normalizing and controlled rolling process.
