摘要： A vortex metal insertion system for a metal recycling furnace, the system
having a molten metal flow cycling through the furnace and through a vortex bowl in the system. The system includes one or more process sensors in the furnace, an automated molten metal flow adjustment device, and a computer controller. The computer controller reads the sensor(s) and adjusts the adjustment device to control the flow of molten metal through the vortex bowl based on the reading(s). The system has an insertion port through which scrap metal and other materials may be controllably inserted into the molten metal flow.

摘要： An overflow system for a doorway exhaust hood on a metal melt furnace having an eductor gas circulator. The system includes a manifold with an inlet near the hood's lower lip, and a conduit between the manifold and eductor. A blower draws gas into the manifold and urges that gas through the conduit, into the eductor, and into the furnace. Sensors detect when the door is open and the volatiles level under the hood. An electronic controller instructs the blower to draw exhaust gases through the manifold when the door is open and the volatiles level exceeds a predetermined level.

摘要： A vortex injection system for a metal recycling furnace a delacquering chamber and a melt chamber, and a molten metal flow channel running through each chamber. The system diverts a portion of the molten metal flow through a vortex bowl, after which that portion of the molten metal flow is then returned to the main molten metal flow. The vortex bowl has an insertion port through which scrap metal and other materials may be controllably injected into the molten metal flow.

摘要： A metal furnace header gate system haying a recirculation port in the furnace, a hot gas generator, a gas blower, and a furnace door. The door has an embedded gas manifold and outlet ports that each connect the manifold to a directional nozzle. The blower draws exhaust from the recirculation port into the hot gas generator, which generates additional exhaust and mixes the exhaust gases together. The blower forces this exhaust mixture into the manifold, through the nozzles, and into the furnace. A computer controls the blower and the hot gas generator to regulate the system.
