摘　　要：文章主要通过研究热定心机在热轧无缝钢管生产中的作用及目前普遍采用的几种热定心机的优缺点,从而设计出一种新型的能定尺定心、能首尾同时定心的双向热定心机。实践证明,该措施对提高壁厚精度具有良好的效果。On the basis of the studies on the effect of hot - centering machine on the production of hot - rolled seamless tubes and the advantages and disadvantages of several types of the present hot - centering machine, A new type of hot - centering machine was designed by ourselves which could realize the length and centre and could centre simultaneously at the head and the end. The actual production proves the machine can improve the accuxacy of the wall thickness.

关 键 词：双向热定心 定尺定心 结构设计
