Aluminum Cans Carbonization Paint Stripping Furnace

The aluminum cans carbonization paint stripping furnace is an industrial device specifically designed for cleaning metal surface coatings. It can remove paint, grease, and other impurities from the surfaces of various aluminum cans, aluminum products, aluminum scrap, and other materials. It is particularly suitable for processing waste aluminum cans, metal paint buckets, aluminum profiles, spray-coated waste aluminum, waste aluminum foil, etc.

This carbonization paint removal furnace utilizes high-temperature pyrolysis technology: in a low-oxygen environment, through precise temperature control (450–480℃), the paint, coatings, and organic impurities adhering to the surface of the aluminum can are decomposed into combustible gases and solid carbides, ultimately preserving the metallic aluminum substrate.

• Pre-treatment Crushing Stage: The crushing equipment can be configured based on the customer's scrap aluminum raw materials. Common machines include dual shaft shredders and hammer crushers, achieving a discharge particle size of 20-40 mm.

• Pyrolysis Carbonization Stage: The material is conveyed into the high-temperature furnace via the conveying system. In the carbonization furnace, the temperature is controlled within a suitable range (usually set according to the coating characteristics) by heating system, causing the organic coating to decompose into combustible gases and a small amount of carbides, while the aluminum substrate itself is completely preserved.

• Exhaust Gas Treatment Stage: The gases generated during carbonization enter the secondary combustion chamber for furnace heating, and are then purified before being discharged in compliance with standards, thus avoiding environmental pollution caused by harmful gases.

Aluminum Cans Carbonization Paint Removal Furnace Advantages

For scrap aluminum processing companies, choosing a suitable aluminum can carbonization paint stripping furnace can bring multiple benefits:

1. Protects the aluminum substrate and improves recycling rate

Aluminum has a low melting point, and improper temperature control can easily lead to aluminum loss during melting. This aluminum cans carbonization paint stripping furnace uses a precise temperature control system to ensure uniform temperature distribution within the furnace. While thoroughly removing the paint layer (paint removal rate can reach 99.9%), it effectively avoids overheating or deformation of the aluminum, maximizing the preservation of the aluminum's weight and physical properties, and improving the recycling rate.

2. Excellent environmental performance

This aluminum cans carbonization paint removal furnace adopts a closed continuous operation design and is equipped with complete waste gas treatment system. The gases generated during carbonization can enter the matching secondary combustion chamber for pyrolysis, and the purification system meets emission standards, complying with current stringent environmental requirements.

3. Controllable operating costs

The equipment uses insulation materials and a thermal circulation design, resulting in high thermal efficiency and full energy utilization. Compared to the waste liquid treatment costs generated by chemical paint stripping, thermal paint stripping has relatively economical operation and maintenance costs, and the operation process is more automated, reducing the intensity of manual labor.

Choosing the right aluminum cans carbonization paint stripping furnace can not only optimize your production process but also improve economic efficiency while ensuring environmental benefits. Besides processing waste aluminum cans, this equipment is also suitable for surface paint and plastic removal from aluminum profiles, aluminum alloy wheels, and spray painting fixtures, demonstrating good versatility.
