Abstract: In this paper, the end-point temperature of converter, the end-point metal content of converter, the metal content of normal sample in continuous casting and the quality of added materials during de-oxidization and alloying are selected as the research objects. The calculation formulas of alloy yield are defined and the yield of samples in different environments is calculated, and the difference of yield among different steel species is analyzed. Then the marginal influence model is used to analyze the influence of molten steel weight...
