Furnace process cycle
Furnace process cycle means the period in which the furnace is tapped to the time in which the furnace is tapped again and includes periods of charging, smelting, tapping, casting and ladle raking. For multiple furnaces operating within a single shop building, furnace process cycle means a period sufficient to capture a full cycle of charging, smelting, tapping, casting and ladle raking for each furnace within the shop building.
