To realize efficient P removal and resource utilization of steelmaking slag, a synthetic slag with appropriate basicity was produced by co-processing the practical dephosphorization slag and basic oxygen furnace slag. The selective leaching behavior and dissolution kinetics of P were investigated. The results indicated that the P …

Steel slag (SS) is an industrial waste generated during the steel-making process. According to World Steel Association (2018), 170 kg of steel slag is produced per ton of crude …

Electroslag welding is an efficient and effective process for joining thick materials in a vertical or near-vertical position. Often used in heavier industries such as shipbuilding and construction, this process produces a uniform bead profile with little porosity or cracking, meaning fewer defects than with other processes.

Sintering is an important process at the transition of ash to slag, which is predominantly initiated by the neck growth between ash particles and is shown in Fig. 12. Sintering of coal ash is a result of phases transformation in solid and liquid states. Sintering of coal ash can be classified into two types: (1) solid-phase sintering and (2 ...

During the melting of steel a multicomponent liquid oxide called slag is formed and floats on top of the liquid steel. The slag is separated from the liquid steel, …

Steelmaking slag includes the following: slag produced in the hot-metal pretreatment processes (desiliconization, dephosphoriza-tion, desulfurization, etc.), slag flowing out …

High-temperature molten steel slag is a large amount of industrial solid waste containing available heat energy and resources. This paper introduces an efficient and comprehensive utilization process of high-temperature molten steel slag. The waste heat energy in the high-temperature molten steel slag can be fully recovered through …

BOF steel slag reduces water at 500 °C and produces high-purity H 2 . Fe 3 O 4 generated can be easily separated and recycled. Typically, 1 kg of slag produces 0.9 mol of H 2. The slag generated has an annual production potential of 85,000 tons of H 2 with no CO 2 generation and even a negative carbon balance with CO 2 sequestration.

This paper reviews the production, processing, and characteristics of steel slag, and its use as a cementing component in different cementing systems. The chemical …

This process produces a pool of molten tin, on top of which floats a slag containing most of the unwanted impurities. At the completion of smelting, the impure tin is tapped off and cast into large slabs, while the slag is solidified into granules by being poured into water tanks. The impure tin slabs go for further refining, and the granulated ...

However, this technology still face various challenges: 1) To obtain high CO 2 sequestration capacity, it is necessary to provide rigorous conditions (high CO 2 concentration, high …
