1. Introduction. During the steelmaking process, various slags are produced as byproducts (Shen and Forssberg, 2003).The first stage of steel production is blast furnace steelmaking, in which raw iron ore is converted into pig iron, which contains various amounts of
The steelmaking slags are referred to by the steel production techniques used, such as BOF, EAF, and ladle furnace etc. These steel making slags typically contain 20–25% iron (Kawatra and Ripke, 2002) cause the chemical composition of steel slags is highly variable, the mineral composition of steel slag
The electromagnetic iron separator is used to remove iron pieces from utilized in iron, steel, cement, and power plants for the removal of iron from slag, thus » Learn More Company Profile, jig machine, gold concentrator, iron separator
Processing and Reusing Technologies for Steelmaking Slag. 3.2 Crushing and magnetic separation. Steelmaking slag contains about 10 40wt% metal iron (exclud ing iron oxides), which is derived from the refining process or from some processing vessel (e.g., the converter, hot metal/molten steel ladle, or
Roughly BOF slag, EAF slag and SMP slag can be defined as steel slags. Reviewing the past, utilization of ironmaking slag has a long history. The broken slag from ironmaking was already REUTER, M., XIAO, Y., and BOIN, U. Recycling and environmental issues of metallurgical slags and salt fluxes. VII International Conference on Molten
Grinding Mill. XSM grinding mills vary from coarse grinding, medium grinding to micro fine grinding.Grinding Mill（Grinder Mill）is widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing.The materials include line, calcite, barite, coal, gypsum, mica and bentonite powder.
Sep 19, 2018 · Abstract. Steelmaking slag with high P 2 O 5 content is generated when using highP iron ores. This slag primarily consists of a CaO–SiO 2 –FeO–Fe 2 O 3 –P 2 O 5 system and is regarded as a potential P source. To separate and recover P, selective leaching of the Pconcentrated solid solution from steelmaking slag was employed.
The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a coproduct of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route.
the molten slag to lower the viscosity and adjust the slag composition making it suitable for making glass ceramics. The liquid slag is air granulated and heat can be recovered. Component modifiion of steelmaking slag in an air quenching process to improve grindability was reported.
rization slag using a slag regenerator P was reduced and concentrated in hot metal, and was further dephosphorized to produce fertilizer material. Yokoyama 5) proposed et al. a magneticseparation method to separate and recycle the Prich phase from steelmaking slag, by exploiting the differences in their magnetic properties.
Technology, Sweden (as a part of the Ecosteelmaking national project in Sweden) and National Metallurgical Academy of Ukraine. A sustainable approach to utilize steelmaking slag components based on transformation of nonmagnetic iron monoxide (or wustite) to magnetite by oxidation has been proposed by the current authors . This allows selective

Read more: Slag product appliions Formerly published as a separate magazine until 2008, slag continues to be more than adequately covered as a regular feature section in Global Cement Magazine.
ing slag has been estimated to be roughly equivalent to the total annual imports of P2O5 into Japan. 4) Hence, if it is possible to separate P2O5 from slag, steelmaking slag will be an alternative resource of P2O5. The composition of steelmaking slag varies considerably according to the type of process, and the conditions in the workshops, for

AN OVERVIEW OF TREATMENT OF STEELMAKING SLAG FOR RECOVERY OF LIME AND PHOSPHORUS VALUES P. N. Chaudhary & J. Pal Scientists, National Metallurgical Laboratory, Jamshedpur ABSTRACT The steelmaking slag containing high phosphorus (13 % P2O5) can not be used in blast furnace, as it increases the refining load. Removal of phosphorus is essential
