Aluminum Ingot Mold Crack Examination Method And Equipment Research

Aluminum ingot continuous casting production line is composed by a number of equipment production chain, which is melted aluminum ingots for the production of automated production lines. This chain of production equipment, once a part of the failure of which would cause the entire system can not operate normally. Therefore, aluminum ingot continuous casting production line fault diagnosis is imminent, According to this huge project, we chose to mold failures in casting machine conduct the research.During the production process of the casting machine, the mold continuous operation by the chain of transmission, after the high-temperature aluminum water pouring into the mold, in order to solidify the aluminum water as soon as possible, we made the molten aluminum in the cooling tank shell mold cycle of cold water to quickly cool. Due to the mold used in carrying aluminum ingots in the hot and cold working environment long time, because of the fatigue in the mold surface, which arises inevitably the crack, even rift. if the crack reaches a certain depth, after the high temperature aluminum water is poured in aluminum mold, cracks caused by the high-temperature aluminum water leakage into the water to produce an explosion, which will result in interruption of the production system, even cause serious industrial accidents. Therefore, the safety of aluminum ingot mold detection is particularly important.The traditional method is according to the eye, ear recognition, and the experience to judge, this method is neither scientific nor efficient. This topic prepares to quote wavelet analysis, fuzzy filtering, FFT and other methods to casting for crack diagnosis. The concrete steps as follows, we construct one examination system platform in the laboratory, including the exciting shake the device, sensor, vibration meter, micro-computer, using sensors collecting knocking vibration signals generated by the mold, and then analyze by using MATLAB software and data processing Technology on the collected vibration signal analysis and processing knocking, then distinguishe the aluminum ingot mold the weary degree, and detection the development trend of crack, so that make the fault detection timely and reliably.This method get rid of artificial factor interference and improve the crack distinguish of speed and efficiency, so as to achieve the purpose, which to avoid accidents and improve production efficiency. Thus, the research of the fault diagnosis method has great significance to support equipment for safe and reliable operation and to promote the development of national economy. The method also can improve the competitiveness of enterprises at the same time. Therefore, this study will have considerable economic value and obvious the social significance.
