并指出了ZWJ型上引纸复卷机双支承辊差速传动的不合理性；

This paper points out that various drive design of double supporting rolls used on ZWJ model up-threading rewinder is irrational .

结果表明：淬火时间为55min，淬火介质为油或UNCON（25%）时，支承辊不能得到马氏体而硬度降低；

The results show that the hardness of bearing roller is lower than the required because no martensite is formed when the quenching time is 55 min and the quenchant is the oil or UNCON ( 25w % ) .

以UNCON（15%）或水为淬火介质时，可以得到大量的马氏体，支承辊硬度和淬硬层深也符合要求，但残余应力较大。

While the bearing roller is quenched into UNCON ( 15w % ) or water , it can get a lot of martensite . At the same time , the hardness and quenching layer of bearing roller meets the needs , but the residual stress is larger .

实验结果表明，在Cr5支承辊用钢马氏体相变结束时，相变塑性应变与应力成线性关系，Greenwood-Johnson模型中的相变塑性参数是与应力无关的常数。

Experimental results show that a linear relationship between transformation plasticity strain and applied stress exists when martensitic transformation completes in the 5 % Cr steel , and the transformation plasticity parameter of the Greenwood-Johnson model is a constant , which is independent of applied stresses .
