Manufacturing Process
At Gulf Street Metal Scrap TR LLC, we employ a technically advanced, environmentally sustainable, and quality-centric metal manufacturing process that transforms scrap into high-performance, specification-grade metal products. Our operations are built on metallurgical precision, process automation, and continuous innovation to meet the exacting demands of global industries.
Process Involved
1. Scrap Collection & Material Segregation
The manufacturing process begins with the strategic collection of post-industrial and post-consumer ferrous and non-ferrous scrap from sources such as demolition sites, fabrication units, automotive dismantlers, and municipal waste streams. Collected materials are pre-sorted using manual, magnetic, and spectrometric methods to classify by alloy family, grade, geometry, and chemical composition.
Proper segregation ensures a homogeneous input feedstock, minimizes cross-contamination, and enables downstream processing tailored to specific metallurgical requirements.
2. Visual & Analytical Inspection
All incoming material undergoes preliminary screening and quality verification to eliminate deleterious substances including oil residues, polymers, paint layers, and other non-metallic inclusions (NMIs). Using portable XRF analyzers, LIBS (Laser-Induced Breakdown Spectroscopy), and optical emission spectrometry (OES), we conduct compositional analysis and positive material identification (PMI) to validate alloy integrity and remove out-of-spec batches.
This stage ensures that only conforming materials progress, protecting refractory linings, reducing slag generation, and aligning with RoHS and REACH compliance.
3. Comminution (Shredding & Size Reduction)
Oversized or irregular scrap is subjected to mechanical comminution using rotary shredders, guillotine shears, and jaw crushers. The objective is to produce size-optimized charge material that enhances melting kinetics, improves charge density, and allows for uniform furnace loading. Size reduction increases the surface-area-to-volume ratio, enabling faster thermal transfer and reducing furnace cycle time.
Embedded foreign particles such as insulation, fasteners, or coatings are also exposed during this step for subsequent removal.
4. Advanced Separation & Purification
Post-shredding, we deploy a multi-stage material recovery system to achieve high-purity metal separation:
• Overhead and drum magnets isolate ferromagnetic constituents
• Eddy current separators extract conductive non-ferrous metals
• Sensor-based sorters using near-infrared (NIR) and X-ray transmission (XRT) distinguish between alloys
• Air classifiers and density separation remove light contaminants
This high-resolution segregation ensures input stream consistency for tight alloy tolerance manufacturing, crucial for structural and electrical applications.
5. Thermal Processing & Melting
• Purified metal fractions are charged into high-efficiency furnaces:
• Electric Arc Furnaces (EAF) for high-volume ferrous melting
• Induction Furnaces for non-ferrous alloys requiring temperature control and minimal oxidation
• Reverberatory Furnaces for aluminum and copper recycling
We leverage real-time temperature sensors, refractory thermocouples, and programmable logic controllers (PLCs) for optimized thermal cycles, energy efficiency, and emissions reduction. Slag conditioning and bath chemistry are monitored continuously to maintain metal purity and furnace stability.
6. Metallurgical Refining & Alloying
•Molten metal undergoes degassing, desulfurization, and deoxidation using fluxes and scavenging agents. Alloying elements such as nickel, chromium, molybdenum, manganese, or silicon are added via wire feeding, ladle metallurgy, or automated alloy dosing systems based on the desired mechanical properties and microstructural requirements.
Real-time spectrochemical analysis and melt sampling ensure composition control, adherence to customer specifications (ASTM, EN, JIS, DIN), and preparation for further casting or forming.
7. Casting & Solidification
The refined molten metal is transferred into preheated refractory-lined molds for static casting or directed to continuous casting lines depending on production requirements. Products are shaped into billets, blooms, ingots, slabs, or near-net shape castings using gravity or pressure casting methods.
For further forming, hot rolling, extrusion, or forging is carried out, depending on dimensional, surface finish, and mechanical property targets. Solidification is controlled to reduce segregation, porosity, and shrinkage defects, ensuring optimal grain structure and dimensional precision.
8. Controlled Cooling & Finishing Operations
Solidified metals are subjected to controlled cooling regimes (air cooling, water quenching, or furnace annealing) to achieve desired microstructure phases (e.g., pearlite, martensite, austenite). After cooling, materials undergo surface treatment (pickling, shot blasting), cutting, deburring, and dimensional calibration.
Final inspections include:
• Ultrasonic testing (UT)
• Hardness testing (Brinell, Rockwell, Vickers)
• Tensile strength and elongation testing
• Microstructural analysis using metallography
9. Packaging, Distribution & Circular Reuse
Finished products are packed with anti-corrosion protection, barcoded for traceability, and dispatched via our optimized logistics network. Clients include OEMs, foundries, steel rerollers, and industrial fabricators across automotive, construction, and heavy equipment sectors.
