And the physical and chemistry performance of slide gate which adding Si-Fe and 3.5wt%content C was improved compared with the conventional Al2O3-ZrO2-C slide gate which contains 9wt% contentC.
Conclusion (1)The physical and chemistry performance of slide gate which was added Si-Fe and 3.5wt%content C was improved compared with the conventional Al2O3-ZrO2-C slide gate which contains 9wt%contentC; The performance of specimens is best when 6wt% Si-Fe was added to the material because excessive Fe will block the nitriding of Si
