钒对水冷金属型离心铸造球墨铸铁管退火工艺的影响

The effect of vanadium on annealing process of centrifugal cast ductile iron pipe of water-cooled metal

在实际生产的条件下，讨论了钒异常对水冷金属型离心铸造球墨铸铁管退火工艺的影响，实验结果表明：为稳定获得铁素体基体的球墨铸铁管应控制钒含量到规定范围，并根据试验结果，提出了钒异常时退火工艺改进措施。

This paper discusses the effect of abnormal vanadium on annealing process of centrifugal cast ductile iron pipe of water-cooled metal in the actual production conditions. The results of experiment show that the content of vanadium should be controlled within the specified scope so as to achieve a stable ferrite matrix of ductile iron pipes, and according to the test results, annealing process measures are put forward when vanadium is abnormal.
