A Review of Granulation Process for Blast Furnace Slag
Blast furnace slag is a by-product of blast furnace (BF) ironmaking produce. Every pig iron production is accompany by 0.3 ~ 0.6 tons of blast furnace slag produced with the temperature of 1350 ~1450 (1600~1 800 MJ sensible heat, equivalent to 55~61kg standard coal combustion after the heat generated). On this basis, the BF slag is up to 247In China, slag crushed stone can replace natural stone for highway, airport, foundation engineering, railway ballast, concrete aggregate and asphalt pavement.It can be used for: preparing slag crushed stone concrete, applying in soft foundation, paving asphalt pavement with slag crushed stone as base material, which is bright and has What is Blast Furnace Slag and How to Process It?

Steelmaking Slag an overview ScienceDirect Topics
Improving process design in steelmaking. D. Sichen, in Fundamentals of Metallurgy, 2005 9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which The quantity of blast furnace slag produced depends on the raw materials charged into the blast furnace. The amount ranges between 0.2 and 0.6 tons per ton of iron produced [ [1],[2],[3] ]. Worldwide production of iron from blast furnaces was approximately 10.6 billion tons between 2005 and 2016, while South Africa produced Comparison of technical and short-term environmental
