Problems solved by technology

[0002] In the existing technology, steel slag is mainly based on the converter process. Steel slag is a by-product of converter steelmaking. Due to its complex and special composition, its effective treatment and utilization has always been a difficult problem in the metallurgical industry, and there are few technologies that can be popularized on a large scale. , the existing steel slag treatment technology is mainly based on the hot stuffing method. The disadvantages of this technology are: low processing efficiency, it takes about 20 hours to stuff the slag once, occupies a large area, causes serious pollution, and is not suitable for the fast-paced production of the converter
