Utilisation perspective on water quenched and aircooled blast furnace
About 500 Kgs sample of each type of slags were collected from four different blast furnaces Two different slag samples (SlagA and SlagB) were considered from the water quenched GBF slags, and the other two were ACBF (SlagC and SlagD) which was a slow cooling by nature In case of GBF, water was quenched/sprayed over The slag produced at blast furnace during pig iron manufacturing is called blast furnace slag The slag produced at steel melting shop is known as steel slag Slag output obtained during pig iron and steel production is variable and depends mainly on composition of raw materials and type of furnace Typically, for ore feed containing 60 to 65%SlagIron and Steel 2017 (2) IBM

Numerical investigation of breakup process of molten blast furnace slag
Blast furnace slag (BFS) is the main byproduct in ironmaking process As its discharge temperature is between 1450 and 1550 °C, each ton of slag contains a large amount of highquality thermal energy which is equivalent to 60 kg standard coal [1,2,3]Thus, there is a great potential for waste heat recovery from hightemperature In this paper, different types of concrete have been elaborated on, in which the cement is replaced by slag from different steel mills, both blast furnace and ladle furnace slag The percentages of slag substitution by cement were Slag Substitution as a Cementing Material in Concrete: Mechanical
Desulfurization Ability of Blast Furnace Slag Containing High Al
In recent years, with the extensive use of high alumina iron ore, the content of Al 2 O 3 in slag has increased greatly, which inevitably affects the metallurgical properties of blast furnace slag [1,2,3,4,5,6,7,8,9,10]Among these metallurgical properties, the desulfurization ability of blast furnace slag plays an important role in the quality of hot The electric arc furnace (EAF) is the main alternative to the BFBOF route Here steel is produced only through scrap fusion EAF is the most important scrap recycling process Scraps, direct reduced iron, pig iron, and additives are melted through highpower electric arcs formed between a cathode and the anodes (Fig 61 ) Fig 61Electric Arc Furnace: Most Efficient Technologies for Greenhouse
