Installation Best Practices and Maintenance for Longevity

Getting the most out of your Corundum Bricks starts with proper installation and regular upkeep. Follow these simple steps to ensure long-lasting performance and minimize downtime.

Installation Steps

• Prepare the surface: Make sure the kiln or furnace lining area is clean and free of dust or debris before laying the bricks.
• Use compatible mortar: Pick a refractory mortar designed for high alumina bricks to keep everything sealed and stable. Avoid cheap or non-certified options.
• Allow for expansion: Leave proper gaps (expansion joints) between bricks to handle thermal expansion without cracking.
• Lay bricks carefully: Place bricks snugly but not tightly packed. Stagger joints to boost structural strength.
• Check alignment: Use a level and straightedge to keep walls even and smooth for better heat distribution.

Maintenance Tips

• Regular inspection: Look for cracks, spalling, or any signs of wear once every few months. Catch issues early to avoid bigger repairs.
• Control temperature changes: Avoid sudden temperature spikes that can damage corundum bricks and cause thermal shock.
• Clean gently: Remove dust and residue using soft brushes or air blowers. Don’t use harsh chemicals that might weaken the brick surface.
• Repair minor damage: Patch small cracks quickly with compatible mortar to prevent expansion.

Troubleshooting Common Problems

• Cracking or spalling: Usually caused by improper expansion space or quick thermal cycling. Check joints and improve heat-up procedures.
• Loose bricks: Can happen if mortar wasn’t applied correctly or if expansion joints are filled. Re-mortar and leave proper gaps.
• Mortar discoloration or erosion: Indicates chemical attack or high moisture levels—consider upgrading to more resistant mortar and improve kiln atmosphere.

By following these steps, your Gotrays Corundum Bricks will provide reliable, long-term service in your industrial setting. Need more help? Download our full installation and maintenance manual or reach out to our support team.
