Two more views of the steel mill facility. Top photo, is the Open Hearth Furnace, the trestle work ( above the 45 ton diesel switcher) is part of the high line to the Blast Furnace. The photo below is of the Blast Furnace, the Blower House-Power House is to the left. Here you will also see a good view of how the dual downcomer piping looks. The Dorr Thickener is between the main line and the blast furnace.
