The stainless steel slag of EAF is a by-product of the stainless steel smelting process in EAF . Generally, the stainless steel slag of EAF contains 40–50 % CaO, 5–10 % Fe 2 O 3, <10 % Cr 2 O 3, and <2 % MnO [13,14,15,16,17,18], which indicates that it has potential recovery value.
Piles of steel slag, a solid waste generated from the iron and steel industry, could be seen due to no utility found for the past century. Steel slag has now gained much attention because of its new applications. The properties of slag greatly influence its use and thus had got varied applications. The chemical composition of steel slag varies as …
Hence, Cr-bearing stainless steel slag (SSS) is rarely employed in the process of SS-CCS if the Cr exists in unstable phases. The authors of this paper studied the effects of chemical composition and cooling conditions on the crystallization behavior of stainless steel slag (Cao et al., 2018; Zhao et al., 2018a,b).
The transition to hydrogen-based reduction processes within the iron and steelmaking industry will generate new types of slag compositions that require valorization routes. Using slags as supplementary cementitious materials (SCMs) addresses the carbon dioxide emissions of the cement industry since the SCM requires neither calcination nor …

Metal recovery. Drop balling. Scrap Metal Services provides steel mill services that include slag processing, melt shop services, & scrap yard management.
The moisture in steel slag when it enters the mill is 6.9%, and the Bond work index of the steel slag is 28.6 k Wh/t. The yield of the mill ground steel slag that is not treated via magnetic separation is 19.98% lower than that which is treated via magnetic separation. From this, it can be seen that the iron content in steel slag is ...
Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current …

Materials based on iron oxide are still the most widely used red pigments. Although the synthetic iron oxide pigment industry has matured, there have been continuous efforts for more circular economy-based methods for the production of pigments. In this study, hematite has been extracted by a hydrothermal method from mill-scale …
Slag practices and conditions that are optimal for stainless steel quality and good refractory performance are defined. Phase equilibria and computer modelling are used to simulate and predict refractory–slag and slag–metal interactions. The slag principles and requirements for ing in the electric arc furnace are discussed.

A statistical analysis by EUROSLAG 67 shows that only 6 % of steel slag is used for global cement production. Utilizing steel slag as a replacement in cement production or as a replacement for cement used in the concrete industry could significantly reduce CO 2 emissions 68-72. Fig.
Introduction. Steel slag is the main solid waste generated in the steel-making process, accounting for 15 to 20% of crude steel output [1]. China's crude steel output in 2021 was 1.035 billion tons [2], more than half of the global crude steel output (1.9505 billion tons) [3], and the steel slag output exceeded 120 million tons.
