ABSTRACT:
The process comprises the steps of mounting two rotary furnaces in series including a smelting station and a charge preheating station, effecting a smelting in the furnace at the smelting station while causing the fumes from the first furnace to pass through the furnace at the preheating station towards an exhaust chimney to preheat the charge in the preheating furnace, and transferring the furnace which is at the smelting station towards a casting station. To enable the various transfers of furnaces each furnace is associated with a transfer support including a device for causing rotation of the furnace.
