What is the best crucible material to melt 316L stainless steel?

[JuiLiu]

I am running into low life-cycles for my crucibles to melt and cast stainless steel 316L. I am currently implementing a AlO2 & SiO2 crucible and its only good for about 12 runs until the crucible drops-out in the bottom. Does any one know any better crucible materials to be used?

Silica ramming mass is acidic in nature and will easily react with Chromium in stainless steel. Did you also encounter any lining failure? You need to use magnesite based basic ramming mass.Talk to your furnace manufacturer,who can help you locate a supplier for basic ramming mass.
