My son and I have the equipment to do a steel complex with 4 blast furnaces from conerstones first steel mill called The Works .Now that they have come out with some new items we plan on adding one more blast furnace add two more coke ovens to the four we have ,one more rolling mill to the two , and one more electric furnace to the two already here. But I have a problem that maybe you fellas can help me with.wall1 Conerstone has come up with a new building for the Ashland Iron and Steel Mill and it's called the Blower Engine House . My problem , does each Blast Furnace have it's own Blower Engine House or not ? How does the Blower Engine House fit in. If any one knows let me hear from ya. I have the book by Freytag but it does'nt cover this subject much.
