2050热轧主作业线卷取机卷筒研制

Development of Coiler Mandrel of Main Working Line in 2050mm Hot Rolling Mill

在２０５０热轧主作业线卷取机卷筒研制工作中，对主要零件材质的选择原则、达到要求的机械性能的热处理方法进行了研究。分析了卷筒失效原因，从扇形板涨缩的运动学分析，提出了正确的卷筒装配调整方法，有效地提高了卷筒的使用寿命。对摩擦付中铜合金零件材质选择的原则和研究方法，也适用于其他主要铜合金零件的研制。

During manufacturing the coiler mandrel for 2050mm hot rolling line,the selective principle of main parts material and the heat treating method according with mechanic properties have been worked out.A correct method for assembling and adjusting the coiler mandrel is adopted to raise the service life of that by using the kinematics of the expansion & shrinkage of segment to analyse the reasons about coiler mandrel defunction.The selective principle and manufacturing method of copper alloy parts material in friction pair are also applicable to the development of other main copper alloy parts.
