The chromium elution behavior of stainless steel (SS) slag depends highly on the chromium distribution, and the molten modification process proved to effectively improve the chromium enrichment in stable phases. However, the phase transformation and variation of chromium stability during the subsequent cooling process is still poorly understood.

Physical and chemical and mineralogical characteristics of LD steel slag. It has been found that the density of LD slag lies between 3.3-3.6g/cm. 3 Due to its high Fe content, steel slag looks in appearance a loose collection, and appears hard and wear resistant. The grindability index of steel slag is 0.7, in contrast with the value of 0.96 and 1.0 for blast furnae slag and standard sand ...

Carlos Thomas, ... Francisco Agrela, in New Trends in Eco-efficient and Recycled Concrete, 2019. 7.1.2 Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.

The amount of SS slag is growing with the increase in demand for stainless steel. However, the toxicity of SS slag is extremely high due to its Cr6+ content [2,3], and untreated SS slag threatens the ecological environment and human health [4–6]. Thus, it improving the chromium stability in SS slag is urgent.
