Aluminum foil products in the production process, often occasionally some anomalies, such as rolling vibration slippage, pressure difficult, speed is limited; aluminum foil double-rolled when the dark side of the bright star; product surface brightness or color difference , Pattern and so on. For these abnormal phenomena, it is generally difficult to sharply, medicine to the disease, must be observed through the field observation, analysis and judgment through the test to find the real reason. Sometimes the same problem, the same phenomenon, its causes may be different, the solution will not be the same. This concealment requires that the technician must have sufficient practical experience and a strong ability to analyze the problem to deal with.
In the aluminum foil foil processing products in the process, often in a process to find product quality defects but has nothing to do with the process, for example, the blank of the internal metallurgical organization defects lead to thin strip or foil material holes, slag, pinholes , Surface anomalies, performance exceeded, etc.; on the surface of the product caused by mechanical damage in the next process on the surface of the product left over the scratch and so on. This transmission, requiring the production operator must strictly abide by the process system, careful operation, and strive to put an end to the process of product quality defects, not on the process of product quality defects into the next process.
