In recent years, scientific researchers and engineering technicians have continuously improved and perfected the purification process of aluminum alloy melt and the corresponding equipment, so that the content of inclusions in the aluminum melt has been continuously reduced, but at the same time, they lack an effective method. Reasonable detection methods for inclusions can accurately determine slag content in the melt and comprehensively evaluate the pros and cons of various purification processes<\/a>. How to determine the content of inclusions in molten aluminum, and how to determine the concentration of inclusions in molten aluminum simply, directly, quickly and accurately before pouring, has always been one of the hotspots of research by scholars at home and abroad. Testing mainly includes identifying its chemical components, observing its shape, size, distribution, and determining its content. Due to the low content of inclusions in the melt and local segregation, the uneven composition of the molten aluminum and other factors lead to poor stability, large dispersion, and poor sampling representativeness of the test results. It is difficult to evaluate the status of the inclusions in the entire melt and can only be relative Qualitative analysis.<\/p>\n

At present, there are many kinds of detection methods for slag content in molten aluminum at home and abroad, mainly divided into offline detection and online detection. The main methods of offline detection include: metallographic method, filtration method, chemical analysis method, electron beam melting method, centrifugal heating method, ultrasonic method, etc. The online detection methods mainly include: LiMCA method, LiMCAlI method, etc. At present, there are many researches on offline detection methods in China, but these methods are performed offline, that is, samples must be taken at the production position, and then the samples are processed and tested in the laboratory, and the results are returned to the production, which is difficult to use on site Online detection cannot accurately reflect the true situation of inclusions in molten aluminum. There are many studies on online detection methods abroad, but its products are more expensive and costly.<\/p>","protected":false},"excerpt":{"rendered":"
