5 Keys to Extend Wear Parts Life in Lost Foam Casting

High-chromium alloys last 3x longer when heat treatment eliminates quenching stress. Here’s how we achieve it.

1. The Failure Mode: Thermal Stress Cracks
In lost foam casting, rapid cooling creates micro-cracks in wear plates and mixer blades. Our metallurgists solved this with:
Proprietary Quenching – Slow-cooling chambers reduce stress by 62% (proven by spectrometer tests)
Post-Cast Tempering – 450°C/842°F treatment boosts impact toughness to 18 J/cm²

2. Why Material Density Matters
EPS foam decomposition often causes porosity. Our V-process + vacuum systems ensure:
▪ 95%+ Density in shield machine cutters
▪ 0 Gas Cavities (X-ray inspection data)

"Dense alloys resist fracture in mining crushers – our KC5A liners last 6,800+ hours."

3. Your Maintenance Cost Killer: Custom Alloys
Not all chromium irons perform equally. We match chemistry to your operation.

4. Beyond Casting: The Finish Fix
Grinding-induced heat softens surfaces. Our solution:

• Cryogenic Machining (-196°C/-320°F) preserves 62 HRC hardness

• Laser alignment ensures ±0.1mm tolerance in crusher parts

Conclusion

"Longevity isn’t luck – it’s science. Partner with labs that own spectrometers, not just furnaces."
