taphole

During and after tapping, the furnace is 'turned around': the slag door is cleaned of solidified slag, repairs may take place, and electrodes are inspected for damage or lengthened through the addition of new segments; the taphole is filled with sand at the completion of tapping.

These furnaces have a taphole that passes vertically through the hearth and shell, and is set off-centre in the narrow 'nose' of the egg-shaped hearth.

They both peered through a peephole into the furnace, did something to — Ada was explaining to a guest — the “slag hole” (different from the taphole, Daeman vaguely noticed) and then the young woman and the older man — soon to be a dead older man, Daeman thought cruelly — leaped from the cupola structure onto the sand and rushed over to look at the mold.
