Abstract

In the method that the oxygen-free copper strips are produced through undercurrent horizontal continuous casting-cold rolling process, there are some coarse grains, microscopic cracks, shrinkage, shrinkage and segregation defects in the oxygen-free copper strip billet, which debase the densities of the strip billet, and are the main reasons for rejected castings during machining operation. Through the orthogonal experiment of the technical factors in the casting process, the mapping model of artificial neural networks have been established using the data obtained in the experiments, which built the relationship among the densities of casting blank and technological factors. With the help of this model, the optimal casting conditions have been researched by using GA optimizations method and real experiments. The results show that micro-structure of castings was improved and the densities of the strip billets are enhanced.
