Slag mineral powder chemical composition

The chemical composition of steel slag is mainly CaO,MgO,SiO 2 and FeO,and their content is about 88% to 92% of steel slag .The main mineral composition of steel slag is dicalcium silicate (C 2 S),tricalcium silicate (C 3 S),RO phase (solid solution of CaO,MgO,FeO and MnO) and a small amount of free calcium oxide (f-CaO).SLAG - IRON AND STEEL - IBMSLAG - IRON AND STEEL 16 Slag - Iron and Steel S lag is a by-product generated during manufacturing of pig iron and steel.It is produced by action of various fluxes upon gangue materials within the iron ore during the process of pig iron making in blast furnace and steel manufacturing in steel melting shop.Ryoji Tsujino's research works Nippon Steel Sumitomo Ryoji Tsujino's 15 research works with 133 citations and 164 reads,including Development of Direct Analysis Method for Molten Steel with Ultra Fine Particle Generation-ICP Emission Spectrometry
