Steel Scrap After Combustion
The recovery of waste tires, through their combustion, produces a by-product named tire wire scrap or tire derived steel (T.D.S.).
.No rubber and fibre contamination is detected since the temperature in the furnace easily reaches 800 °C and all contaminants (rubber/fibre) are completely burned. The scrap is not in shredded form.
This iron scrap is harmonic steel and it doesn’t contain dangerous and toxic substances as highlighted from the tab below:
|Oil & Fats||% p/p||<1|
|Dust with granulometry||%p/p||<0.01|
|Halogenated Organic Solvents||mg/Kg||<0.01|
|Aromatic Organic Solvents||mg/Kg||0.003|
|Nitrogen Organic Solvents||mg/Kg||<0.01|
The wires after being mechanically cleaned are stored as part of bales. The Bale dimensions are the following 35cm x 35cm x 40cm, weight: about 95 – 100 Kg, density: 3,8Kg/dm3.
The wire pre-treated presents the following chemical composition:
|C||S||N||O||Mn||Si||p||Cr||nI||Cu||Sn||Zn||Met. Fe||Tot. Fe|
This material, mechanically cleaned and compacted, shows low content of Cu, Ni, Sn (elements that are undesirable in normal commercial steels) and with low P content (element that is considered undesirable in special steel)
The packing in high density bales also guaranties the following advantages:
- Facilitates the handling and storage procedures.
- Permits to redeem the transportation cost and custom clearance costs, since we can manage to fit 24-25 Tons in a 20’Upgrade container, depending on the demands of our customers.
- The material is a product ready for the feeding of the Electric Art Furnace and it doesn’t require further handling and packing procedures
