When it comes to furnace lining, the refractory material you use and the compaction method go hand in hand. Using the right lining vibrator for your refractory ensures optimal density, reduces lining failures, and maximizes furnace life.
In this guide, we break down the most common refractory types and explain how LeisterTech’s lining vibrators are tailored to handle each one efficiently.
Common Refractory Materials Used in Induction Furnaces
| Refractory Type | Characteristics | Typical Applications |
| Alumina | High alumina content, wear-resistant | Steel melting, high-temp zones |
| Silica | Acidic, good thermal shock resistance | Non-ferrous metal melting |
| Magnesite | Basic, good slag resistance | Steel foundries, basic lining |
| Chrome Magnesite | High abrasion resistance | Heavy-duty furnaces, aggressive slags |
| Fireclay | Economical, moderate temp resistance | Backup lining, lower temp zones |
How Lining Vibrators Adapt to Different Refractories
Each refractory material behaves differently during compaction—some need gentle vibration; others require more forceful, high-frequency vibrations.
1. Alumina-Based Refractories
Challenge: Heavy and dense; require strong vibration to remove air pockets.
LeisterTech Solution: High-amplitude vibrators with adjustable RPM (2200–2800) to compact alumina mixes effectively.
2. Silica-Based Refractories
Challenge: Brittle, prone to cracking if over-vibrated.
LeisterTech Solution: Vibrators with fine RPM control to deliver low amplitude, high-frequency vibration that preserves integrity while compacting.
3. Magnesite & Chrome Magnesite
Challenge: Coarser grain sizes; need deep vibration to penetrate layers.
LeisterTech Solution: Vibrators equipped with larger vibration heads and longer shafts for deeper penetration and uniform compaction.
4. Fireclay
Challenge: Lightweight, needs delicate handling to avoid segregation.
LeisterTech Solution: Adjustable vibration settings to prevent over-vibration and segregation.
