During continuous-casting and rolling Al-Cu wire rod

the leakage of emulsified oil and lubricant oil could often be observed in the three-roller mini-stand

resulting in the pollution of emulsified oil and lubricant oil.Through analyzing the experiences from the production process

a very effectively detection method of detecting leakage of the stand was presented

which could treat various leakage phenomena in-time.So the high efficient stable running of the stand could be ensured

and the product quality was improved.
