Furnace Turn-around:
Furnace turn-around is the period following achievement of tapping till the furnace is recharged for the next heat. Throughout this period, the roof and electrodes are raised and the furnace lining is inspected for refractory damage. If essential, repairs are made up to the hearth, slag-line, tap-hole & spout. In the case of a bottom-tapping furnace, the taphole is filled along sand. Repairs to the furnace are made up utilizing gunned refractories or mud slingers.
