Bogie Furnace. This furnace is for holding hot steel ingots to equalize their temperature before they are hot-rolled in a steel-making or rolling mill complex. Normal practice is to charge ingots into the soaking pits immediately after stripping from the moulds whilst they are still hot. Soaking pit temperatures are generally controlled at 1300°C.
