Why Furnace Cleaning Is Strategic

In the light alloy foundry sector, keeping furnace refractory walls free from corundum and slag build-up is essential to ensure:

• Optimal thermal efficiency
• Reduced energy consumption (up to 25% less)
• Improved quality of molten metal
• Longer refractory lifespan

The Problem with Corundum

Corundum, an extremely hard aluminum oxide, builds up over time on furnace walls, leading to:

• Loss of thermal insulation
• Increased melting time and costs
• Risk of alloy contamination
• Higher hydrogen absorption and porosity in the metal

JODOVIT’s Solution: PULEX 325 and PULEX 325P

What It Is

• PULEX 325: Exothermic powder flux for intensive cleaning
• PULEX 325P: 500 g tablet version for weekly maintenance
  Both products are designed for use in reverberatory, radiant roof, and combustion furnaces containing aluminum alloys.

How It Works

• Effectively removes corundum and slag, even from hard-to-reach areas
• Facilitates the detachment of deposits with simple scraping
• Reduces hydrogen absorption in the metal bath
• Enables faster, cleaner melting cycles

Key Benefits

Energy Efficiency

• Up to 25% reduction in energy consumption
• Faster melting cycles

Environmental

• Lower CO₂ emissions
• Less waste thanks to improved metal quality

Economic

• Extended refractory life
• Fewer plant shutdowns and emergency interventions

Choosing PULEX 325 and PULEX 325P means investing in productivity, quality, and sustainability.

A simple yet strategic maintenance approach, already adopted by numerous foundries to optimize furnace performance.
