Metal recovery from contaminated metal scrap

摘要

A metal reclaiming system and method for reclaiming metal from scrap material is provided. The system has a furnace (12) and a controller (106) for controlling operation of the system. The controller (106) operates the metal reclaiming system in a first operating mode in which the furnace (12) is operated at a first temperature in the range of 350° C. to 550° C. to incinerate pollutants and drive off volatile organic compounds (VOCs) from the scrap material without melting the metal. The controller (106) is operates the metal reclaiming system in a subsequent operating mode in which the furnace (12) is operated at a further, higher temperature to melt metal in the said scrap for reclaiming.

主权项

1. A method of reclaiming aluminum from scrap material, the method comprising:
loading said scrap into a tiltable furnace(12); operating said furnace (12) in a first mode by heating said scrap in said furnace at a first temperature in the range of 350° C. to 550° C. to drive off Volatile Organic Compounds without melting the aluminum; operating said furnace (12) in a second mode to remove particulate material from said furnace; operating said furnace in a third mode by raising the temperature of the furnace (12) to melt said aluminum; and tilting said furnace (12) to remove molten aluminum through a discharge port (24).
