In industries like metal casting and foundries, refractory linings are critical for withstanding extreme temperatures. But it’s not just the material that matters—how you install the lining is equally important. One of the most overlooked aspects of this process is the proper use of lining vibrators.
Choosing the right vibrator based on the refractory mix ensures better compaction, reduces the chance of air pockets or cracks, and extends the service life of your furnace.
Let’s explore how LeisterTech helps industrial professionals get it right.
Understanding Refractory Materials
Different refractories respond differently to vibration. Knowing their characteristics is key to ensuring the best compaction results:
Material Key Traits Common Applications
Alumina High density, wear-resistant Steel melting, high-temp areas
Silica Acidic, shock-resistant Non-ferrous furnaces
Magnesite Basic, slag-resistant Steel foundries
Chrome Magnesite Tough and abrasive-resistant High-wear furnace zones
Fireclay Lightweight, cost-effective Backup and low-temp linings
Explore LeisterTech’s full range of vibrators designed for these materials.
Choosing the Right Vibration Approach
Each refractory material requires a unique vibration technique. Here’s how LeisterTech lining vibrators are optimized for specific scenarios:
Alumina
Challenge: Heavy and dense—needs strong vibration to eliminate trapped air.
LeisterTech Solution: High-amplitude vibrators with variable RPM (2200–2800) for deep compaction.
Silica
Challenge: Brittle; can crack if over-vibrated.
LeisterTech Solution: Low-amplitude, high-frequency units ensure safe, even compaction.
Magnesite & Chrome Magnesite
Challenge: Coarse grains require deeper penetration.
LeisterTech Solution: Long shafts and heavy-duty heads for effective compaction across thick layers.
Fireclay
Challenge: Lightweight and prone to segregation if over-vibrated.
LeisterTech Solution: Fine-tuned vibration settings to prevent material separation and ensure consistency.
