BOF and EAF Steels: What are the Differences?

2016/3/7The 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).

Silicon Wafer Production

In this process, MG-Si is first ground in a ball-mill to produce very fine (75% 40 M) particles which are then fed to a Fluidized Bed Reactor (FBR). There the MG-Si reacts with anhydrous hydrochloric acid gas (HCl), at 575 K (approx. 300C) according to the reaction: Si + 3HCl → SiHCl 3 + H 2. The hydrochlorination reaction in the FBR
