离心球铁管组织和元素的分布

The Distribution of structures and Elements of Centrifugal Cast Ductile Iron Pipes

本文研究了水冷金属型离心铸造球墨铸铁管铸态组织和退火组织的分布特点,分析了各元素沿管壁及在各相中的分布,探讨了各元素对退火的影响机理。

In this paper, we have studied the distributive characteristic of cast and annealing structure of centrifugal ductule iron pipes casted in water cooled metallic mould, and distributions of various elements along pipe wall and in various phases have been analyzed with the help of EMPA
