Abstract: A scrap melter for light gage metal scrap includes a shrouded impeller connected to a shaft, the shaft connected to a rotary power device. The shrouded impeller is immersed in a molten metal pool in a charge bay or furnace. It is inclined at an angle relative to the vertical. The shrouded impeller creates a vortex in the molten metal pool, which includes a whirlpool at the surface of the molten metal. The center of the whirlpool is horizontally displaced from the shaft so that scrap can be charged into the whirlpool to be ingested into the vortex. The shrouded impeller creates a vortex for scrap ingestion and pumps molten metal for re-circulation through the melting system without the need of a separate pump.
