Abstract:Stainless steel industry generates a large amount of chromium-containing solid waste every year. China has a huge demand for chromium resources in the future and relies heavily on imports. Recycling chromium resources in stainless steel waste can not only alleviate the demand for chromium resources in China, but also have a positive significance for environmental protection. The current detoxification treatment method for chromium-containing stainless steel wastes is based on the reduction of toxic Cr6+, mainly including dry reduction method, wet reduction method and solidification method. Glass-ceramics has the characteristics of thorough detoxification and large processing volume. It is one of the methods for the comprehensive utilization of chromium-containing stainless steel waste with good application prospects,which is the future direction of key development.
