16MND钢管
我的产品热处理硬度HRC只能是60HRC,59或61HRC我都不能接受？经常遇到受委托的热处理产品硬度值只能在某一个确定值上，不能有偏差。比如要求热处理硬度达到60HRC，你热处理之后达到59HRC，或61HRC就视为不合格产品。殊不知，洛氏硬度机的允许偏差还在1HRC呢。你和他解释热处理道理，他（她）会摆出一副上帝的面孔：你想不想做我的热处理产品？市场竞争嘛。

太重(天津)滨海重型机械有限公司首座具有完全自主知识产权的400英尺自升式钻井平台——“TZ301-1”，日前在天津临港基地起运，将发往墨西哥湾进行作业服务。该钻井平台应用了衡钢无缝钢管生产的X80Q海洋桩腿支撑管。海洋钻井平台“服役”环境恶劣，作为平台支撑部件的海洋桩腿支撑管，需要具备优良的低温韧性、焊接性能、疲劳性能和抗腐蚀性能。衡钢无缝钢管凭借技术、营销、装备和生产的综合优势，采用微合金化设计、洁净钢冶炼、高精度轧管工艺、高水平热处理工艺以及严格的无缝钢管质量管控等措施，成功研发X80Q海洋桩腿支撑管新产品，并实现该系列产品小批量试订单到规模化大生产的推进。近年来，衡钢无缝钢管不断强化技术创新，自主研发了海洋桩腿支撑管、海洋钻井隔水管、海洋桩腿主（半）弦管、海洋高压泥浆输送管等一系列海洋工程用管，无缝钢管质量达到先进水平，为推动我国高端海洋装备国产化作出了积极贡献。

要想将冷却速度控制在9～12℃／s，经计算应在2风机段开始相变，在4风机段之前完成相变。2风机应全开，3风机开85％左右或全开(取决于轧件温升情况)，目的是使线材在相变过程中温度尽可能稳定在630℃左右，即近似等温转变，同时相变在很短的时间内完成，以获得片间距极小且均匀的，保证在获得高强度的基础上，具有良好的韧性。相变完成之后，一方面要使线材不断降温，另一方面如果降温速度太快，势必造成应力增大，影响线材力学性能，所以4～10风机可适当减低开启度。
