Electric Arc Furnaces vs. Blast Furnaces | Service Steel

Modern blast furnaces use coke, or purified coal, to melt iron ore and create pig iron. Oxygen is then injected into the furnace, to reduce the carbon content of the steel and remove impurities. Blast furnaces take up a lot of room and produce a lot of carbon dioxide, but are easier to make clean steel with.
