摘　　要：为解决漆包线铜米漆膜的脱除问题,利用离心式摩擦装置,以铬铁矿砂作为摩擦介质,使铬铁矿砂与漆包线铜米进行充分摩擦,从而达到铜米脱膜精制的目的。根据铜米脱膜工艺,考察了铬铁矿砂粒径、离心式摩擦装置转子转速、铬铁矿砂与铜米混合比、摩擦循环次数等因素对铜米脱膜率的影响。结果表明,漆包线铜米脱膜最佳方案为:铬铁矿砂粒径为325μm、离心式摩擦装置转子的转速为2 700 r/min、铬铁矿砂与漆包线铜米混合比为1. 5∶1、摩擦循环次数为15次,在此最优条件下漆包线铜米脱膜率为96. 65%,满足了直接回收利用的条件。In order to solve the problem of removing the copper-coated paint film of enameled wire,the centrifugal friction device is used,and the chromite sand is used as the friction medium to fully rub the chromite sand and the enameled copper wire to achieve the copper film stripping refining purpose.According to the copper stripping process,the effects of chromite sand particle size,centrifugal friction device rotor speed,chromite sand and copper-to-copper ratio,and number of friction cycles on the stripping rate of copper were investigated.The results show that the optimal solution for stripping copper wire: the particle size of chromites and is 325μm, the rotor speed of the centrifugal friction deviceis 2 700 r/min, and the mixing ratio of chromite sand and enameled wire copper is 1.5 :1.The number of friction cycles is 15 times.Under this optimal condition, the stripping rate of the enameled wire copper rice is 96.65 %, which satisfies the conditions of directrecycling.
