无缝钢管淬火机组的合理选型

Type Selection of Seamless Pipe Quenching Machine

介绍了国内外常见的无缝钢管淬火机组的类型,描述了各种类型无缝钢管淬火机组的设备组成、结构特点和工作原理,分析了各种类型淬火机组的优缺点和适用范围。提出了合理选型的建议:"入槽+内喷淬火机组"和"入槽+旋转+内喷淬火机组"技术落后,不宜选用";旋转+入槽+内喷淬火机组"适用于大直径、大壁厚的钢管;"外淋+内喷淬火机组"适用于中小直径、中薄壁的钢管";隧道式淬火机组"适用于小直径、薄壁的钢管及高合金钢管。

The paper introduces the common types of seamless pipe quenching machines domestic and abroad, describes their equipment constitution, structural features and working principles and analyzes their advantages, disadvantages and range of application. The author puts forward suggestions for machine selection that ＂positioning ＋ inner spraying quenching machine＂ and ＂positioning ＋ rotation ＋ inner spraying quenching machine＂ processes should not be chosen and applied due to their outdated technology, ＂ rotation ＋ positioning ＋ inner spraying quenching machine＂ process is suitable for large diameter and thick wall pipe, ＂outer ＋ inner spraying quenching machine＂ process for medium and small diameter and medium wall pipe, and ＂tunnel type quenching machine＂ for small diameter and thin wall pipe and high alloy steel pipe.
