摘要： PURPOSE:To obtain a steel pipe which effectively suppresses the occurrence of hydrogen type defects by disposing a hardening water tank and a tempering furnace in series between a run-out table provided to a finish rolling mill and a transfer table provided in parallel in the side surface part thereof. CONSTITUTION:A steel pipe rolled by a finish rolling mill 1 is received on a runout table 2. A hardening water tank 3 and a tempering furnace 4 are connected to the side face part in the position just before the table 2 in the direction intersecting orthogonally with the longitudinal direction of the table 2, and a rolling material cooling bed 5 is provided in parallel with these and is connected to a transfer table 6 in parallel with the table 2. Then, in spite of setting the direct hardening stop temp. at about above 200 deg.C, it is possible to perform directly tempering without lowering the steel pipe temp. down to about below 150 deg.C in the air cooling process after this, thus the improvement in treatment performance and the suppression of hydrogen type ultrasonic defects are made possible.
摘要翻译：目的：为了获得有效地抑制氢型缺陷发生的钢管，将硬化水箱和回火炉串联设置在设置在精轧机的出口台和在侧面平行设置的转移台之间其表面部分。构成：用精轧机1轧制的钢管被接收在跳动台2上。硬化水箱3和回火炉4在与正交相交的方向刚好在工作台2之前的位置处连接到侧面部分与工作台2的纵向方向，并且轧制材料冷却床5与它们平行地设置，并且与转台6平行地与工作台2连接。然后，尽管设定了直接硬化停止温度。在大约高于200℃的情况下，可以直接回火而不降低钢管温度。在此之后的空气冷却过程中降至大约低于150摄氏度，从而可以改善处理性能和抑制氢型超声波缺陷。
