Therefore, the type of nodulizer, and the choice of nodulizer, is particularly important for the overall process of the cast iron process.
In addition, since the fluctuation range of the density of the spheroidizing agent during the casting process is relatively large, some spheroidizing agents even react too strongly, and thus the safety performance for the casting process cannot be ensured. Those skilled in the art can also prevent the problems of large fluctuation range of density and too intense reaction of the nodulizer by changing the components of the nodulizer and adding various functional components, but the potential problems are that magnesium light and dense smoke in the reaction process are not less and the environmental protection problem is also extended.
