When lining induction furnaces, refractory selection and compaction go hand in hand. Using the correct lining vibrator not only improves density and structural integrity, but also extends the life of your furnace. The key? Matching the vibrator to your specific refractory material.
At LeisterTech, our lineup of precision-engineered lining vibrators is designed to work with a variety of refractory types—ensuring effective, efficient compaction every time.
Common Refractory Types and Their Applications
Every refractory has unique properties that influence how it responds to vibration. Here's a quick comparison:
Refractory Type Properties Typical Use Alumina Dense, highly wear- resistant Steel melting zones Silica Acidic, resists thermal shock Non-ferrous metal melting Magnesite Basic, good slag resistanceSteel foundriesChrome MagnesiteVery abrasion-resistantFurnaces with aggressive slagsFireclayLightweight, cost-effectiveBackup linings, lower-temperature use

How LeisterTech Vibrators Adapt to Each Refractory
Each refractory mix requires a different vibration approach to ensure full compaction without damage.
Alumina
- Issue: Heavy mix, prone to air pocket formation.
- Solution: High-amplitude, RPM-adjustable vibrators (2200–2800 RPM) for deep compaction.
Silica
- Issue: Brittle structure can crack under excess vibration.
- Solution: High-frequency, low-amplitude vibration to compact gently.
Magnesite & Chrome Magnesite
- Issue: Coarse grains require deep penetration.
- Solution: Long shafts and large heads ensure uniform compaction in thick layers.
Fireclay
- Issue: Lightweight material can segregate with over-vibration.
- Solution: Customizable RPM to avoid material separation and maintain consistency.
