The Carbon Cost of Slag Production in the Blast Furnace:

2017-8-27  To determine the part of CO2due to the slag production inthe BF process route (carbon cost of slag), a differentialreasoning can be developed. The difference in overallemissions of an increase of slag quantity while keeping thehot metal production exactly at the same level should givea reliable estimate of the CO2impact of the slag quantity.In order to assess the CO2due to the production of slagover the range of

2012-4-4  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 increases the total interfacial area and consequently the rate of slag–metal reactions.
