Blast Furnace Slag - an overview ScienceDirect Topics
2017-10-18 7.2.2 Blast-furnace slag BFS is a by-product obtained in the manufacture of pig iron in the blast furnace. It taps out from the blast furnace as a molten liquid at a temperature of 1400°C–1500°C and occurs either as a crystalline or granulated form depending on the treatment method for the molten liquid slag.
