Fire Refining Furnace

FIRE REFINING FURNACE

 

Fire Refining Furnace is intended for pyrometallurgical recycling of copper scrap under a cost-saving and environmentally friendly technology and obtaining electrotechnical copper products with a controlled content of impurities and grade no worse than E-Cu 58 2.0065 (DIN). The basic technology offered regards the production of molten copper suitable to produce FRHC (Fire Refined High Conductivity) copper rod, strip, billet or other copper products using copper scrap as raw material (Cu>92%).

The potentiality of the combustion and refining systems have been calculated for a refining cycle (from charging to reduction) of 16 hours max, if the scrap mixture and the working procedures are used, leaving 8 hours or less for the pouring operation.
