First, this article introduced 2 grade of rotary kiln principle of work and the equipment, to rolled the circle mechanics behavior to carry on the analysis, proposed - rolled the circle - under roller's rotary kiln overall modelling based on the tube body - kiln liner - big tooth ring, to rolled the circle - under roller's contact stress to carry on the finite element analysis the method, and obtained rolled the circle contact stress the size and the distribution rule, finally indicated that rolled the circle contact stress mainly to have two main peak values and the sudden change in one week, appeared is rolling the circle and the under roller contact area; Then, rolls the circle the stress to regard as is the principal stress unknown plane stress test, the use quite mature modern test technology, proposed rolls the circle stress test the principle and the plan, and to rolled the circle the stress to carry on the scene test, the stress which the scene test analysis result and the finite element analysis calculated has compared, had proven the whole method modelling's finite element analysis method's rationality and rolled the circle - under roller contact stress the result accuracy; Finally, uses ANSYS APDL the re-development technology, in view of 2 grades of rotary kilns, rolled the circle - under roller contact stress the overall finite element analytic method to carry on the re-development.

首先，本文介绍了2档回转窑工作原理和装置，对滚圈的力学行为进行了分析，提出了基于筒体-窑衬-大齿圈-滚圈-托轮的回转窑整体建模，对滚圈-托轮的接触应力进行有限元分析的方法，并得到了滚圈接触应力的大小和分布规律，结果表明滚圈接触应力在一周内主要存在两个主要的峰值和突变，都出现在滚圈与托轮接触区域；然后，把滚圈的受力看成是主应力未知的平面应力的测试，利用比较成熟的现代测试技术，提出了滚圈应力测试的原理和方案，并对滚圈的应力进行了现场测试，现场测试分析结果与有限元分析计算出的应力相比较，证明了整体法建模的有限元分析方法的合理性和滚圈-托轮接触应力的结果的正确性；最后，利用ANSYS的APDL的二次开发技术，针对2档回转窑，就滚圈-托轮接触应力的整体有限元分析法进行了二次开发。

通过模拟分析比较，揭示出了环件轧制过程中的金属流动规律：轧制时，环件外侧的变形最大，厚向中心部位变形最小，内侧的变形程度介于中间；环件内外环面的压应力分布和变化规律：在垂直于环件轴线的对称面上，压应力分布近似对称状态，而且在对称面上的应力最大，往端面方向开始减小；指出了环件轧制中轧辊与环件摩擦对环件成形的影响：对于环件的宽展变形，摩擦的影响很小，可以忽略；分析了环件进给速度对环件成形的影响并阐述了环件厚向中心部位凹陷产生的原因，提出防止凹陷的措施：在轧制时，尽量使用快的进给速度有利于防止端面凹陷的产生；研究了导向辊位置对环件成形以及轧辊受力的影响：导向辊的位置对环件的宽展变形影响很小，但对轧辊的受力影响较大，当导向辊的中心位置位于毛坯初始中心位置之上时，驱动辊和芯辊的受力相对较小，这是导向辊导向时优先考虑的位置。
