This topic starts with a contribution from Shuai Wang et al., who studied smelting of vanadium titanomagnetite (VTM). VTM is used to obtain vanadium pig iron, which is later converted to steel and commercial vanadium slag.4 Such ores are processed using blast furnaces and, most commonly, electric arc furnaces. Higher titanium …

From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly 13.5 × 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc …

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.
