Every aluminum can looks simple on the outside—but for recycling plants, that colorful coating is a serious problem.

Paint, ink, and organic coatings reduce aluminum purity, increase slag loss, and directly impact melting efficiency. This is exactly where an Aluminum Cans Paint Removing Furnace becomes a game-changing solution.

If you’re involved in aluminum can recycling, scrap aluminum processing, or secondary aluminum smelting, understanding this furnace is no longer optional—it’s essential for higher recovery rates, lower costs, and cleaner aluminum output.

What is an Aluminum Can Delacquering Furnace?

An aluminum can delacquering furnace is a thermal treatment system used to remove paint, varnish, ink, and organic coatings from used aluminum cans before smelting.

Unlike directly burning the paint during the smelting process (which leads to oxidation and metal loss), this furnace preheats and pyrolyzes the coatings in a controlled environment.

The result?

• Purer aluminum
• Higher metal recovery rate
• Lower smelting energy consumption

This type of furnace is also commonly known as:

• Aluminum can decoating furnace
• Aluminum can paint removal furnace
• Scrap aluminum paint removal furnace
• Carbonization of UBC cans

What is Aluminum Cans Paint Removing Furnace

Why Delacquering is More Important Than You Think

Here’s a statistic many recyclers underestimate:

• Paint and organic coatings can cause up to 3-5% aluminum loss during direct smelting.
• Now, imagine that loss over thousands of tons per year.

Major Problems Without a Delacquering Furnace

• Excessive oxidation and slag formation
• Reduced aluminum recovery rate
• Increased fuel consumption
• Polluting exhaust emissions
• Reduced furnace lifespan

In contrast, pre-delacquered aluminum cans melt faster, cleaner, and more efficiently.

How Does an Aluminum Can Delacquering Furnace Work?

Step-by-step working principle

• Feeding
  Shredded or baled aluminum cans are fed into the furnace.
• Controlled Heating (400–550°C)
  The furnace heats the aluminum cans to a temperature below the melting point of aluminum.
• Coating Pyrolysis
  The coatings decompose into gases instead of violently burning. Afterburner system
  Released gases are safely combusted, reducing emissions.
• Clean aluminum product output
  The paint-stripped aluminum cans can be efficiently melted down.

🔥 Aluminum remains solid.
🎨 Paint is removed.
💰 Value increases.

Frequently Asked Questions (FAQ)
1. Does the furnace melt aluminum cans?

No.
The furnace operates below 660°C, aluminum’s melting point. It removes paint without melting the metal, which prevents oxidation loss.

2. Can it process printed, colored, or coated cans?

Yes.
It is specifically designed for:

Beverage cans

Food cans

Printed aluminum packaging

Lacquered aluminum scrap

3. Is it suitable for small recycling plants?

Absolutely.

Modern systems come in:

• Small-capacity batch furnaces
• Medium continuous furnaces
• Large industrial rotary or tunnel furnaces

Scalable solutions exist for both startups and large smelters.

4. What fuel does the furnace use?

Common options include:

• Natural gas
• Diesel
• LPG
• Electricity (in some regions)

Energy recovery systems often reuse heat from exhaust gases.

5. How much efficiency improvement can it deliver?

On average:

• 2–5% higher aluminum recovery
• 10–20% reduction in melting energy
• Significantly lower slag generation

Over time, this translates into fast ROI.

If your business processes aluminum cans at scale, a paint removing furnace is no longer a luxury. It’s a profit protection tool, an energy saver, and a quality booster rolled into one.

In a market where margins are tight and sustainability matters more than ever, this furnace helps recyclers:

• Recover more aluminum
• Spend less on fuel
• Produce cleaner, higher-value metal

And that’s a competitive edge you can’t afford to ignore.
