Basic Oxygen Furnace Steelmaking
A big difference between the two steelmaking processes however is in the capital investment costs involved. Whilst a typical integrated (i.e. BOF-route) steel mill today costs ~$1100 per tonne of installed capacity, a medium-size EAF-route mini-mill today costs under $300 per tonne in terms of the initial capital outlay.
Mineralogy of Metallurgical Slags
The BF-BOF route contributes to 60% and the EAF route to 40% of the European steel production . Subsequently, the liquid steel is further treated in various aggregates, and the resulting slags are referred to as secondary metallurgical slags. Consequently, there are three main types of present ferrous slags: 1. BF slag. 2. BOF …
