Description
 

Tire Wire scrap coming from the combustion of waste tires

 The recovery of waste tires, through their combustion, produces a by-product named tire wire scrap or tire derived steel (T.D.S.).
Since the material is formed from thin wires (average diameter of  0,20 – 0,80mm), its surface can easily oxidize due to its morphology.

At visual inspection, the scrap appears as a hank of long wires characterized by the presence of few ash and iron oxide. No rubber and fiber contamination is detected since the temperature in the furnace easily reaches 800 °C and all contaminants (rubber/fiber) are completely burned. The scrap is not in shredded form.
This iron scrap is a harmonic steel and it doesn’t contain dangerous and toxic substances as highlighted from the tab below:

The output obtained from the combustion of tires is then re - processed an pretreated in order to arise its performance and the melting ratio . The wires are mechanically cleaned in a rotating screen in order to reduce the dust and are then compacted in high density bales.

The Bale dimension  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:

This material, mechanically cleaned and compacted, once melted, permits to obtain steels with 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 manage to fit 24-25 Tons in a 20’Upgrade container

·         The material is a product ready for the feeding of the EAF and it doesn’t require further handling and packing procedures

 In order to guarantee the highest recovery ratio, this material must be melted with other kind of wreckages as Sponge Iron/HBI, then balanced adding HMS Non CI ,NON GI to the blend.
