| Abstract: | Stainless steel dedusted ash is harmful to the environment for it contains a lot of heavy metal irons.Whereas it contains much valued elements such as Ni,Cr,Fe and so on.So it has great social and economic benefits to treat the dust ash harmlessly.This paper mainly introduces the application status of reducing the ash directly in submerged arc furnace to recycle the stainless steel dedusted ash.Then it provides some suggestions for the treatment of the stainless steel dedusted ash in China. |
