650轧机机前工作辊道辊颈的故障分析

Malfunction Analysis of Roller Neck to 650 Rolling Mill Roller Road in Front of Mill

就影响生产中工作辊道辊颈的断裂问题,从理论计算公式和实际生产状况进行了全面、详细地分析和计算。在理论上就设计手册中的计算公式与采利柯夫公式进行比较,阐述了两种公式的不同之处,就现场情况进行了验算,找出了用设计手册中计算公式验算工作辊道辊颈受力情况的不尽合理的地方。将走访几个厂家现场情况,逐一作了分析,找出了生产中工作辊道辊颈的断裂问题的几个主要因素,并提出预防措施。

In this paper,crack problems of roller neck effccting the production in roller road is analysed and calculated wholely,in view of theory calculate formula and practice produce status.In theory,it have compared in calculation and caili-kefu formula and found some different.Form the practice checking,some irrationality status that using ealuculation formula in the design volume check the force of computation roller road and roller reck were found,interviewed several factory about their locate conditions and detailedly analysed them.Moreover,find out some mostly factors of crack problem of roller reck in the production and put forward some preventing measures.
