形变热处理应用于钢管生产的研究在日本、苏联已取得了不少成果。近年来,我国也开展了大量的研制工作,为地质、煤炭、水文和石油等钻采及工程建设提供了一批性能优异的高强度钢管。钢铁研究总院和上钢一厂合作,在减径余热淬火的深化研究、设备研制和工艺试验等方面取得了成效,将50Mn和34Mn钢管性能分别提高到DZ55、DZ60和N-80、X-95的水平。产品经试用,效果良好,并且节能效果显著。 Deformation heat treatment applied to the study of steel pipe production In Japan, the Soviet Union has made many achievements. In recent years, China has also carried out a large amount of research and development work, providing a batch of high-strength steel pipes with excellent performance for the drilling and construction of geology, coal, hydrology and petroleum. Steel Research Institute and the cooperation of a steel plant in the reduction of afterheat quenching deepening research, equipment development and process test results achieved, the 50Mn and 34Mn steel pipe performance were increased to DZ55, DZ60 and N-80, X- 95 level. Product trial, the effect is good, and energy-saving effect is remarkable.
