Product Performance

Furnace Cleaning Agent is a special cleaning agent designed for aluminum alloy furnace cleaning processes.

It is mainly used to clean hard slag accumulation on the furnace wall and furnace bottom after aluminum and aluminum alloy melting operations.

The product reacts quickly with slag deposits under high-temperature furnace conditions, helping separate hardened slag from the furnace lining while reducing damage to the furnace body.

Applications of Furnace Cleaning Agent

AdTech Furnace Cleaning Agent is widely used in:

• Aluminum melting furnaces
• Aluminum alloy holding furnaces
• Billet casting furnaces
• Foundry aluminum melting systems
• Aluminum scrap remelting operations
• Continuous aluminum casting production lines

It is suitable for most aluminum and aluminum alloy melting applications.

What Is Furnace Cleaning Agent?

Furnace Cleaning Agent is a special chemical cleaning material used to remove hard slag accumulation from furnace walls and furnace bottoms during aluminum and aluminum alloy melting operations.

During aluminum melting, oxide slag, aluminum residue, and impurities gradually build up inside the furnace. Over time, these hard deposits reduce furnace efficiency, increase heat loss, affect molten aluminum circulation, and shorten refractory service life.

Furnace Cleaning Agent reacts with hardened slag under high-temperature conditions, reducing slag viscosity and helping separate slag from the furnace lining surface. After treatment, the slag becomes loose and easier to remove, helping improve furnace cleanliness and molten aluminum quality.

The product is widely used in:

• Aluminum melting furnaces
• Aluminum alloy holding furnaces
• Billet casting operations
• Aluminum scrap remelting
• Foundry aluminum production
• Continuous aluminum casting systems

AdTech Furnace Cleaning Agent helps aluminum producers maintain stable furnace performance, reduce downtime, improve molten aluminum cleanliness, and extend furnace service life.

Why Use Furnace Cleaning Agent?

During aluminum melting and holding, oxide slag and aluminum residues gradually accumulate on furnace walls and furnace bottoms.

Without proper furnace cleaning, these accumulations create several production problems.

Reduced Refractory Service Life

Heavy slag accumulation damages the refractory lining and shortens furnace service life.

Increased Heat Loss

Slag buildup reduces thermal efficiency and increases energy consumption during aluminum melting.

Reduced Furnace Volume

Accumulated slag decreases effective furnace capacity and affects molten aluminum circulation.

Poor Molten Aluminum Cleanliness

Furnace buildup may increase oxide inclusions and impurity contamination inside molten aluminum.

Modern aluminum casthouses use furnace cleaning agents regularly to maintain stable melting conditions and improve production efficiency.

Features of AdTech Furnace Cleaning Agent

Rapid Slag Reaction

Furnace Cleaning Agent quickly reacts with slag deposits and generates significant heat energy during furnace cleaning operations.

This rapidly increases slag temperature and improves slag separation efficiency.

Reduced Slag Melting Point

The halides inside the furnace cleaning agent rapidly melt during treatment and reduce the melting point and viscosity of the slag.

This helps separate slag from furnace walls and furnace bottoms more easily.

Easy Slag Removal

After treatment, the slag becomes loose and easier to remove using slag cleaning tools.

This significantly reduces labor intensity during furnace maintenance.

Continuous Production Capability

The product supports continuous aluminum alloy melting and casting operations by reducing the need for long furnace shutdown cleaning procedures.

Reduced Furnace Damage

Because the furnace cleaning process separates aluminum from slag effectively, the furnace body experiences less mechanical damage during slag removal.

This helps extend furnace service life.

Improved Molten Aluminum Quality

Continuous slag removal helps reduce:

• Oxide inclusions
• Gas bubbles
• Slag contamination
• Melt cleanliness instability

This improves overall aluminum alloy quality.

How Furnace Cleaning Agent Works

During furnace cleaning, the product reacts with hard slag deposits under high-temperature conditions.

The cleaning reaction helps:

• Increase slag temperature rapidly
• Reduce slag viscosity
• Separate slag from refractory surfaces
• Loosen hardened slag accumulation

As the slag structure becomes loose, it can be removed easily from furnace walls and bottoms.

At the same time, aluminum trapped inside the slag can separate more effectively, helping reduce aluminum loss.

Recommended Usage Process

Step 1 – Aluminum Refining

When the aluminum alloy temperature reaches approximately 660–720℃, refining agent may be added for hydrogen removal treatment.

The refining process mainly removes dissolved hydrogen from molten aluminum.

Step 2 – Slagging Treatment

After refining treatment, slagging agent is added and fully stirred to remove slag and impurities from molten aluminum.

Step 3 – Covering Treatment

After slag cleaning, covering agents such as expanded graphite or expanded perlite may be spread on the molten aluminum surface to reduce hydrogen absorption and maintain temperature stability.

Step 4 – Furnace Cleaning

After aluminum melting and alloy treatment operations, Furnace Cleaning Agent is used to clean furnace walls and furnace bottoms.

This helps maintain stable furnace operation and molten aluminum cleanliness.

Advantages for Aluminum Casthouses

Improved Furnace Efficiency

Cleaner furnace surfaces improve heat transfer and melting efficiency.

Reduced Production Downtime

Regular furnace cleaning reduces the need for long shutdown maintenance procedures.

Lower Labor Intensity

Loose slag structure makes cleaning easier and reduces manual cleaning effort.

Better Aluminum Melt Quality

Cleaner furnace conditions reduce contamination risks during aluminum melting and casting operations.

Longer Furnace Service Life

Reducing slag buildup minimizes refractory damage and extends furnace lining lifespan.
