COPPER FURNACES
Reverberatory-Refining
Continuus-Properzi provides Reverberatory Refining Furnaces that cover all the different sizes of Copper Casting Lines from small ones, which produce 10,000 tons per year, up to large ones producing 75,000 tons per year.
This technology is designed and capable to process copper scrap into liquid metal with a controlled content of impurities. The production of this molten copper is suitable to produce FRHC (Fire Refined High Conductivity) copper rod, strip, billets or copper ingot.
Continuus-Properzi patented a new design in 2010, introducing an important evolution of the old 20th Century model of Reverberatory Furnaces.
As a major difference, the charging door is now located on the roof of the Furnace thereby allowing a faster, simpler, and more automatic operation. The loading system can be accomplished via a skip charging machine or an industrial belt conveyor. The second system is the most advantageous for big size furnaces allowing many tons of scrap to be charged in just one minute.
The Reverberatory Furnace can be fed with 100% copper scrap with minimum 94% Cu that could be a mix of many different kinds of copper scrap thereby saving hundreds of dollars per ton on the raw material!
The refining know-how developed and optimized in several installations during the last 25 years is the key of the profitable operation that Properzi can offer to Client worldwide!
MAIN ADVANTAGES
| Easy charging system | Constant temperatures during charging | Less energy losses |
| Improved total thermal efficiency | Faster charging phase | Less thermal shock on the furnace’s refractory |
| Quantity of loadable scrap | Less fumes |
RAW MATERIAL
KANAL OR BIRCH
This type of scrap contains unalloyed copper wire having a minimum copper content of 96%.
SECOND CLASS SCRAP (BIRCH AND CANDY)
Comprised of small diameter wire without insulation (telephone wire, copper plates and wire with varnish or paper insulation, clean large and small diameter copper tubes).
GRANULAR COPPER (CLOVE)
Chopped wire without insulation with minimum copper content of 99%.
THIRD CLASS SCRAP (DREAM)
Normally a mixture of miscellaneous unalloyed scrap having an average nominal copper content of 92% (the copper content of the different scrap is in the range of 94%-88%).
