Steel Tire Wire Scrap (TDS): Complete Guide to Tire Derived Steel Recycling and Applications
Introduction to Steel Tire Wire Scrap
Steel tire wire scrap, also known as Tire Derived Steel (TDS), is a high-quality light melting steel scrap recovered from waste tires through advanced tire recycling processes. With the continuous growth of global vehicle usage, millions of tires reach the end of their service life every year, creating serious environmental and waste-management challenges.
Tire recycling plays a crucial role in addressing this issue by converting end-of-life tires into valuable reusable materials such as rubber granules, textile fibers, and high-carbon steel. Among these recycled outputs, steel tire wire scrap stands out due to its high carbon content, excellent tensile strength, and consistent metallurgical quality.
Originally engineered to withstand extreme pressure, heat, and mechanical stress in tire applications, reclaimed tire steel meets widely recognized industry standards and is highly demanded by steel mills, foundries, and manufacturers worldwide.
What Is Steel Tire Wire Scrap (Tire Derived Steel)?
Steel tire wire scrap is the recovered steel reinforcement found inside:
-
Passenger Car Tires (PCR)
-
Truck and Bus Tires (TBR)
-
Off-the-Road Tires (OTR)
This steel is embedded in tires in the form of bead wire and belt wire, providing structural strength, durability, and performance under harsh operating conditions.
After recycling, this material is commonly referred to as:
-
Steel Tire Wire Scrap
-
Tire Derived Steel (TDS)
-
Reclaimed Tire Steel
Key Features of Tire Derived Steel
Steel tire wire scrap is preferred in steel manufacturing due to the following characteristics:
-
High carbon steel composition
-
Strong and durable structure
-
Clean and consistent scrap quality
-
Excellent melting efficiency
-
Suitable for multiple industrial applications
Because of these properties, steel tire wire scrap is widely used as a secondary raw material in modern steel production.
Steel Tire Wire Scrap Production Process
The production of tire derived steel involves advanced mechanical processing and magnetic separation techniques to ensure high purity and maximum material recovery.
1. Waste Tire Collection
End-of-life tires are collected from:
-
Automotive service centers
-
Municipal waste facilities
-
Scrap yards
-
Fleet operators
Before processing, tires are sorted by size and type to improve recycling efficiency and output quality.
2. Tire Shredding Process
Collected tires are processed using industrial tire shredders, which reduce them into smaller pieces. This process usually includes:
-
Primary shredding (large tire chips)
-
Secondary shredding (smaller fragments)
Shredding enables efficient separation of steel, rubber, and textile components.
3. Magnetic Steel Separation
After shredding, the material passes through high-intensity magnetic separators that extract steel tire wire from rubber and textile fibers.
-
Multiple magnetic stages improve steel recovery
-
High separation accuracy ensures better scrap quality
This stage is critical for producing market-ready steel tire wire scrap.
4. Cleaning and Purification
Recovered steel undergoes additional cleaning processes to remove:
-
Rubber residues
-
Textile fibers
Mechanical cleaning, air separation, and vibration screening are used to achieve low contamination levels, meeting steel mill and foundry requirements.
5. Compacting and Baling
Clean steel tire wire scrap is compacted into:
-
Bundles
-
Bales
-
Briquettes
Compacting improves transportation, storage, and handling efficiency, making the material suitable for both domestic and international trade.
