Blast Furnace Core

Starts the Hot blast furnace.

The core's facing decides which two walls take the taps and which two take the tuyeres, so a core laid the wrong way round leaves the structure short of cells with nothing but a count to say why. Ctrl plus shift and right-click on it projects the build outline for the courses above. One block serves every tier, where the cold furnace of Iron Industry Expanded has a core per tier: the tier gate moves to the wall, which takes tier 3 refractory brick and nothing else.
