“…Therefore, they are also known as “self‐dusting” or “falling slags” 35. The monoclinic β‐polymorph is transformed by a martensitic type transformation to the orthorhombic γ‐polymorph with volume expansion which causes the buildup of high internal stress that disintegrates the slag to a fine powder which makes it challenging to handle and store as it gets dispersed into the atmosphere easily 36.…”

“…Thus, high‐alumina slag is more stable than its low‐alumina counterpart. The red mud found in the aluminum industry can also be used industrially to stabilize the C2S phase 36, 46, 47. It is a by‐product generated from bauxite while extracting aluminum dioxide, and the red mud acts as a reducing agent while stabilizing the C2S phase.…”

Ladle slag is a byproduct formed during the ladle refining stage of steel making. It is a dusty material that has been considered industrial waste. Technical advancements towards a sustainable industry led to the development of different applications for ladle slag. Depending on the processing methods during the steel slag production and the weathering of the slag post‐production, the elemental composition of the steel slag largely varies. Owing to this, its characteristics cannot be generalized and specific applications depending on the sources are developed. It is generally used in construction materials, soil rejuvenation, and CO2 capture. This paper reviews the production process, the mineralogical and morphological properties, stabilization techniques, and the applications of ladle furnace (LF) slag. One of the prime focuses of waste remediation and sustainable industry is to find meaningful ways to turn waste into products. In this respect, a comprehensive review of the properties of LF slag and its current application will help provide a framework for the development of future sustainability goals. With increased slag usage, the ladle refining process of steelmaking can be turned into a more carbon‐neutral process.

Calculation results and analysis of changes in thermal radiation density of arcs by wall height for hundred-ton arc furnaces at different slag layer height and at equal arc power are presented. It was found that with an increase in the height of the slag layer from 70 to 300 mm, that is, with an increase in the depth of the arcs in the slag, the density of thermal radiation flows of the arcs in the most heat-loaded part of the walls decreases by 2 times. The efficiency of arcs increases with the increase in the depth of arcs in the slag and increases by 1.61 times when fully buried.
