The mixing behavior of compositional modifiers into viscous liquid BOF slag was studied using fluid flow modeling under industrially relevant conditions. The Volume of Fluid-Large Eddy Simulation-Discrete Phase Model was used to simulate the gas-solid particle-liquid slag turbulent flow. The area fraction of the particle migration zone was …
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 ...
slag milling process. At the same time, the separa tio n efficiency was improved. 2. 1. Materials and characterization Three types of steel slags from Panzhihua Iron and Steel, China were investigated. Briefly, BOF slag (Slag A ) is the slag from basic oxygen furnace used for steel liquid smelting, while desulfurization
The use of the BOF slag as an aggregate in civil construction and road ballast is well-known but the presence of high free lime in the slag results in the swelling of the grains over time. ... CaSO 4, in a laboratory ball mill. Specimen cubes were made using powder, sand and water as per the IS standards of cement testing and their compressive ...
This paper provides an overview of the different types of steel slag that are generated from basic-oxygen-furnace (BOF) steelmaking, electric-arc-furnace (EAF) …
During steel production in a Basic Oxygen Furnace (BOF), for every ton of crude steel produced, 300–400 kg of slag is produced in an highly energy intensive process which requires significant amount of electrical energy produced through coal-based thermal power plants as in the case of South Africa, leading to additional solid waste generation …

In the two last decades, world production of pig iron and steel has undergone a significant increase. In 2018, 1252.87 and 1806.46 million tons of pig iron and steel, respectively, were produced as compared to …
BOF slag and the current status of development of new application technologies. 2. General Condition of Iron/Steel Slag 2.1 How iron/steel slag is produced ... an efficient process using crushers, magnetic separators, and screens (they are arranged in such a way to allow for simultaneous
Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
The BOF slag comprises C 4 AF, C 2 F, RO, and β-C 2 S and γ-C 2 S phases [106], [13]. Due to the high proportions of C 4 AF, C 2 F, and RO phases with elevated Fe content (including metal-Fe), the reactivity of BOF slag is lower than that of BFS [106], [13]. Consequently, adding BOF slag as an SCM in concrete reduces its …

A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.
The main challenge of the steel industry for the next decade is the steel production transformation process, starting in Europe. The CO 2 intensive blast furnace/basic oxygen furnace (BOF) route will be substituted by a combination of Direct Reduced Iron (DRI), based on natural gas, later on "green" hydrogen, with an Electric Arc Furnace (EAF) or a …
Goal: To develop technologies that will result in the beneficial use of BOF slag. The scope of this four-year project is three-fold. First, MTU researchers seek to increase the efficiency of iron unit recovery from BOF/BOP slag. Second, the project calls for the development of value-added feedstocks for steel mill furnaces that will generate energy

The aim of this study is to investigate the utilization possibilities of steel slags, basic oxygen furnace (BOF) and electric arc furnace (EAF) slags, as backfill material in coastal structures.
To avoid the volume expansion of basic oxygen furnace (BOF) slag for use in building materials, a hot slag modification process was proposed to reduce free CaO (f-CaO) in the molten slag. A transient 3D numerical model of BOF molten slag modification by SiO2 particles was established. The flow and heat transfer of molten slag, movement …
