使用4种不同壁厚外径为17.82mm的Zr-4合金半成品管,在KPW25LC轧机上使用相同的参数轧制Φ9.53mm×0.60mm成品管,同炉退火后和矫直后检测不同工艺下的氢化物取向并对比分析,结果表明,冷轧Q值对成品管材的氢化物取向影响至关重要,确定成品轧制Q值与氢化物取向因子的规律,明确管材氢化物取向的影响和控制措施。

Using four kinds of Zr-4 alloy semi-finished pipe with different wall thickness and outer diameter of 17.82mm, the same parameters were used to roll Φ9.53mm × 0.60mm finished pipe on KPW25LC rolling mill, annealed in the same furnace and tested after straightening The results show that the influence of the cold rolled Q value on the hydride orientation of the finished pipe is of crucial importance. The rule of the Q value and the hydride orientation factor of the final product rolling is determined, and the influence and control of the hydride orientation of the pipe material Measures.
