外端加厚油管喷雾正火技术

Spraying Normalizing for Endthickening Oil Pipe

探讨了外端加厚油管的喷雾正火装置和工艺，提出了高温快冷、低温缓冷的工艺措施，取得了工件力学性能合格。

The spraying normalizing device and process of the oil pipe with thick wall in ends are developed,rapid cooling at higher temperature and mild cooling at lower temperature is proposed.The works with excellent mechanical properties and little distortion are achieved.
