| Abstract: | Research and production practice was carried out on quenching process, aiming at the quality problem of internal quenching crack occurred during quenching process of medium and large wall thickness tube. Mechanism of internal quenching crack is elaborated, and a practical and effective opti- mized quenching process-- external spray ＋ axial flow＇ and ＇ soak quenching ＋ axial flow＇ is brought forward with notable effect achieved. Principle, method and technique of preventing tube quenching crack were successfully applied on the development of full water quenching process for certain crack sensitive steels. |
