S1: Industrial Metal Decoating & Orkusparandi bræðslusamþætting
UBC okkar (Notuð drykkjardós) afhúðunarkerfi fellur beint inn í álbræðsluofna, búa til óaðfinnanlega lokaða lykkjuferli. Með því að fjarlægja húðun og aðskotaefni fyrir bráðnun, kerfið hámarkar endurheimt málmhlutfalls á meðan það dregur úr orkunotkun um 15–30%. Húðunar-bræðslutengingin útilokar tvöfalda meðhöndlun, lágmarkar oxunartap, og tryggir hágæða álframleiðsla fyrir downstream forrit.
Samþætt hitauppstreymi
UBC aflakkering tengd bræðsluofni dregur úr gasnotkun um 15-30%. Húðunarkerfið fellur beint að útblásturshitakerfi bræðsluofnsins, skapa lokaða hringrás hitauppstreymis. Heitar útblásturslofttegundir frá bræðsluofninum forhita aflakkarhólfið, meðan á hreinu, Húðað UBC fer inn í ofninn við hækkað hitastig - sem dregur úr orkunni sem þarf til að bræða. Þessi varmatenging útilokar þörfina fyrir aukabrennara á aflakkunarstigi og lækkar heildarnotkun jarðgas í gegnum vinnslukeðjuna.
Build the decoating line around the incoming aluminum scrap.
A connected project can combine size reduction, ferrous and non-ferrous separation, controlled thermal decoating, off-gas management, melting and ingot handling. The final scope depends on the coating system, scrap density, contamination and downstream metal specification.
From incoming UBC bales to a controlled furnace feed
The line should be configured as a material-to-output system rather than a standalone furnace.

- 02Shredding and size control

What changes the equipment list
A reliable proposal starts with the actual scrap profile and the agreed delivery boundary.
Feedstock form
Loose cans, compacted bales, mixed packaging scrap, painted profiles and oily turnings require different opening, feeding and separation arrangements.
Coating and contamination
Paint, ink, lacquer, polymer film, olíu, raka, iron and non-metallic contamination influence residence time, gas handling and downstream metal cleaning.
Downstream route
Decoated scrap may be sold, remelted on site or integrated with refining, casting and automatic stacking. Each route changes utilities and layout.
Environmental boundary
The off-gas train must be selected against the coating chemistry, local permit basis, fuel system and required monitoring points.
Design decisions that protect metal value and operating stability
Published figures are planning references and require project confirmation. Representative feedstock testing and a documented acceptance basis are required.
Atmosphere control
Limit uncontrolled air ingress and monitor the thermal environment to reduce oxidation risk and maintain repeatable coating removal.
Material balance
Record incoming scrap, separated contaminants, decoated aluminum, residues and optional molten-metal output.
Heat integration
Evaluate recovered process gas and hot exhaust as project energy streams only after their composition and stability are understood.
Acceptance plan
Agree sampling, test method, run duration, product cleanliness, emissions boundary and utility conditions before commercial acceptance.

| System block | Typical scope | Configuration basis |
|---|---|---|
| Material preparation | Bale opening, shredding, sizing and controlled transfer | Scrap form, density and required furnace feed |
| Separation | Magnetic, eddy-current and manual or sensor-based quality control | Iron, non-ferrous attachments and non-metallic contamination |
| Thermal section | Controlled decoating reactor, seals, heating and discharge | Coating load, residence basis and oxidation control |
| Environmental section | Gas combustion or oxidation, particulate and polishing stages | Coating chemistry and local emissions boundary |
| Downstream metal | Cooling, storage, optional melting, casting and palletizing | Target product and agreed delivery scope |

Svör skilgreina verkfræðileg mörk; þær koma ekki í stað dæmigerðra efnisprófa eða staðbundinna eftirlits.
What information is required to configure an aluminum decoating line?
Provide the scrap category, coating or oil condition, bale or particle dimensions, mengun, tiltækt magn, downstream metal route, site utilities and local environmental basis.
Can one standard line process every type of aluminum scrap?
Nei. UBC baggar, painted profiles, automotive scrap and oily turnings can require different opening, aðskilnað, feeding, thermal and gas-treatment arrangements.
Is melting and ingot casting always included?
Nei. The project can stop at cleaned scrap or include melting, refining, casting and palletizing when those interfaces are part of the agreed scope.
How should project acceptance be defined?
Acceptance should state the tested feedstock, sampling method, stable operating period, material balance, product-cleanliness basis, utility conditions and environmental measurement boundary.
