高速线材轧机锥套故障分析与改进

Malfunction analysis of taper sleeve of high-speed wire and rod mill and its countermeasures

高速线材生产线精轧机、预精轧机使用的锥套 ,在材质、结构、处理工艺及生产操作上存在诸多不当之处 ,为此进行了多项改进 ,使锥套故障彻底排除 ,使用寿命达 3～ 5月 ,而价格仅为进口件的 1/ 3。

The material, structure, treatment processing and operation of taper sleeves are unreasonable,which used in finishing and prefinishing mill of high-speed wire and rod production line. Therefore, some countermeasures are put forward,and the faults are removed.Meanwhile,the service life of taper sleeves can be reached 3～5 months and its cost is one third of imported one.
