Tire Wire Scrap or Steelcord Scrap is a steel scrap obtained during the shredding process of used tires.
During the granulation process, the partial textile fibers and the steel filaments are separated mechanically from the rubber matter and are addressed to a magnetic device for its separation and collection.
It is a harmonic steel with high content of Carbon that can be up to 0,80% and it bronze –coated as highlighted by the chemical analysis below:
At a visual inspection the material appears in shredded form and formed by very thin filaments.
During the mechanical processing, the separated steel wire is usually contaminated by rubber and fibers that can arise to 20% depending on the usury of the blades which shred the end use tires.
The average rubber contamination of our material is about 15% and it is classified as ISRI 281Processed tire wire (Ferrous)—Grade 4.
The material is packed in big bags, in order to facilitate the handling and storage of the material.
The big bags size is about: 1,1 m x 1,1 m x 2 m with around 1 MT weight.
Please note that the packingsystem is integrated in the shredding plant: this guarantees that the fresh material produced is immediately packed and protected from weather agents in order to avoid the surface oxidation of the wires.
The Big Bags can been loaded in 40’HC container where we manage to fit up to 27MT in order to redeem the transportation cost.
