MOVABLE SWEAT HEARTH FOR METAL MELTING FURNACE

摘要

Exemplary embodiments provide a movable sweat hearth for use with a metal melting furnace having a wall provided with a metal-loading entrance. The sweat hearth includes a hearth body movable relative to the furnace into and out of contact with the wall of the furnace at the entrance. The body has exterior walls enclosing a hollow interior except at a furnace-engagable side wall of the hearth body provided with an opening communicating with the interior. The interior has a floor adapted to support a charge of scrap metal, and the opening is positioned relative to the floor to allow molten metal to drain from the interior through the opening. The floor is arranged at an angle to horizontal to slope in a downward direction towards the opening when the container is moved into sealing engagement with the wall of the furnace with the opening aligned with the furnace entrance. Other exemplary embodiments relate to a combination of a movable sweat hearth as described above and a metal melting furnace having a front wall provided with a furnace entrance.
