Investigation on the Effect of Cooling Condition on Chromium Elution from Stainless Steel Slag

Abstract:

The effect of cooling condition on the chromium elution from stainless steel slags was investigated. The experiments were carried out in a muffle furnace and an induction furnace, and the leaching test was according to the standard procedure, prEN12457-2. The results show that the oxidation atmosphere enhances the elution of chromium, and the dissolving amount of chromium increases with the increase of temperature. The reducing atmosphere could restrain the elution of chromium. Therefore, it is better to take advantage of the neutral or reductive atmosphere for slag cooling in order to reduce the elution of chromium from stainless steel slag.
