摘要： A heating module for a furnace with a process zone. The module includes one or more Silicon Carbide heating elements in a refractory plug. The heating lengths of the elements extend, exposed, from the plug and do not engage one another, but may be positioned to cross over each other. The plug is releasably positioned in the furnace with the heating lengths exposed to the process zone. The plug can be positioned in an array of heating modules, which can be releasably positioned in the furnace with the heating lengths exposed to the process zone.

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： An evaporative cooling system for a scrap metal furnace with an afterburner, a rotary kiln and a conveyor that loads scrap metal into the kiln. Pressurized water runs through water lines to two water spray subassemblies. The first subassembly sprays atomized water into a heating duct between the afterburner and a gas recycle return duct. The second subassembly sprays water onto the scrap metal on the conveyor. Water flow through the subassemblies is regulated by one or more water flow controllers, pumps and/or flow sensors, which may be computer controlled. A water heater warms the water to a desired temperature.

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 push gate for a scrap metal furnace with a volatizing chamber and a doorway into that chamber. The push gate includes a door plate to seal against the doorway, a scoop sized to fit in the volatizing chamber, and a plunger attached to the scoop that extends through the door plate. The push gate is movable. When the push gate is positioned such that the door plate seals against the doorway, the plunger can controllably move the scoop in and out of the chamber to push scrap metal to predetermined positions in the chamber for predetermined periods of time.

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.
