The answer lies in capital costs. For a BOF firm, the average cost per ton of capacity is 1,100, while the cost for an EAF minimill per ton of capacity is only 300. The barrier for entry is thus lower for EAF firms, which can in part explain the rise of such "minimills" over the last half of the 20th century and into the 21st (WikiInvest).
