| 摘 要： | 国内自行设计制造的100 t RH真空循环脱气设备的真空度可达67 Pa以下,真空处理能力为500kg/h以上。生产实践表明,氩气流量越大,钢水循环速度越大,高真空脱气时间越长,钢水脱气效果越明显,所处理的管线钢的氢、氧、碳含量可分别降至1×10-6、20×10-6和20×10-6以下。

| Abstract: | A 100 t RH unit with less than 67 Pa and vacuum degassing capacity up to more than 500 kg/h is de-signed and manufactured at home. Production practice show that the more recirculation rate of liquid steel with increasing argon flow rate and the longer degassing time at high vacuum, the more obvious degassing effect; the hydrogen, oxygen and carbon content; line steels could respectively decrease to less than1×10-6, 20×10-6 and 20×10-6 |
