| Scrap Shredders |
Reduce end-of-life vehicles, appliances, machinery, and structural components into manageable pieces. |
Mixed metal scrap is fragmented before downstream separation. |
Liberates steel from attached materials and prepares it for efficient sorting and remelting. |
Shredding is normally followed by magnetic, density, or sensor-based separation. |
| Magnetic Separators |
Separate ferrous steel and iron from non-ferrous metals and non-metallic materials. |
Recovered ferrous material becomes a cleaner scrap stream. |
Improves scrap quality, reduces contamination, and supports repeated recycling of steel. |
Permanent magnets and electromagnets are both used, depending on feedstock and equipment design. |
| Electric Arc Furnaces |
Melt steel scrap and, where required, direct-reduced iron or other iron units. |
Solid metallic charge is converted into liquid steel using electric arcs. |
Enables scrap-based steelmaking and can use a high proportion of recycled steel when suitable scrap is available. |
Some EAF operations can use up to 100% scrap charge; the actual mix depends on chemistry, availability, and product requirements. |
| Basic Oxygen Furnaces |
Convert hot metal from a blast furnace into crude steel by blowing oxygen through the molten charge. |
Hot metal is combined with a controlled quantity of steel scrap. |
Reintroduces recycled steel into an integrated production route and uses scrap as both a metallic input and a coolant. |
Scrap proportion varies by furnace practice, raw-material quality, and thermal balance. |
| Ladle Metallurgy Furnaces |
Adjust steel temperature, chemistry, cleanliness, and alloy content after primary melting. |
Molten steel is refined in a ladle before casting. |
Improves control over variable scrap chemistry and helps prevent rejected batches and material loss. |
Common operations include alloy adjustment, deoxidation, desulfurization, and temperature control. |
| Continuous Casting Machines |
Solidify liquid steel into slabs, blooms, or billets for subsequent processing. |
Liquid steel becomes semi-finished products in a continuous operation. |
Reduces the need for separate ingot handling and enables internal crop ends and off-cuts to return as recyclable steel scrap. |
Continuous casting is the dominant route for producing semi-finished steel in modern plants. |
| Rolling Mills |
Shape slabs, blooms, or billets into sheet, plate, sections, bars, and wire rod. |
Semi-finished steel is reduced and formed through controlled rolling passes. |
Process off-cuts, crop ends, and rejected material can be collected and returned to the steelmaking cycle. |
Product dimensions and tolerances are controlled through roll gap, temperature, and speed adjustments. |
| Scrap Compactors and Briquetting Presses |
Compress loose sheet scrap, turnings, and other low-density steel residues. |
Loose or oily metal residues are formed into denser briquettes or bundles. |
Improves storage and transport efficiency, reduces handling losses, and can support more consistent furnace charging. |
Briquetting parameters must be matched to particle size, moisture, oil content, and the intended melting route. |
| Dust and Sludge Treatment Systems |
Collect and process iron-bearing dust, sludge, and fine residues generated during steel production. |
Fine residues are filtered, classified, agglomerated, or treated before reuse or controlled disposal. |
Recovers iron units and limits the amount of steelmaking residue sent to landfill. |
Treatment requirements depend on zinc, lead, alkali, oil, and other contaminants in the residue. |
| Quality Inspection and Sorting Systems |
Identify steel grade, surface condition, dimensions, and contaminants throughout production and recovery. |
Material is classified for direct reuse, remelting, reprocessing, or controlled treatment. |
Better traceability and separation help preserve alloy quality and reduce downcycling or unnecessary rejection. |
Methods may include chemical analysis, optical inspection, electromagnetic sensing, and dimensional measurement. |
