| Abstract: | The influence of alloy element content when adding protective agent in the lead - calcium master alloy production is discussed in the article. The impact of changing the cooling - down method and the size of cast ingot etc. to the elemental segregation is also described here. Alloy element＇s segregation behavior in alloy is learned by multi- point testing and metallographic analysis. The influence complication of segregation of Ca, Al when pro- ducing lead and calcium master alloy, sampling and testing methods were ascertained, which have important guiding significance in real productivity. |
