Abstract Scope |
Quality assurance of material is a critical parameter to prevent an increasing reject rate production. As all unacceptable product cause of impurities involves rework or rejection, which directly lead to production losses. Aluminum with silicon will impact of Fluidity. According to the content of some impurities, silicon metal can be divided into different grades.
INALUM uses silicon metal grade 441 to produce foundry alloy A356.2 with a maximum iron content of 0.12 wt %. An unidentified silicon metal method will impact impurities' undefined content, such as iron content (Fe). Although still unable to identify the distribution of iron content in each bag, several works have been developed. In this work, a new method with high accuracy of characteristic material with composite and homogeneity tests has been proven to reduce the reject rate of products and discussed to seek the opportunity to expand a complex method by using machine learning. |
