Cerabolts are used to easily overlay existing fiber module linings with a new blanket veneer. They penetrate tightly into existing modules while holding a new layer of the blanket on the face. This works great on both walls and roof areas to re-establish an effective lining without having to replace the modules.
There’s never a good time for furnace linings to fail. When your furnace’s ceramic fiber module lining is in trouble, you have questions:
- How long can I let this problem ride before I have to repair it?
- What’s the quickest and least expensive way to fix it?
- How can I minimize my furnace downtime?
When Repairs are Needed
With Cerabolts, you can easily refurbish a lining that’s in poor condition, while postponing major repairs indefinitely – without tear-out, disposal, or welding of new anchor studs.
Cerabolts can also be used to upgrade a lining’s temperature rating. For example, a furnace with 2300°F modules can be veneered with 2600°F or even 3000°F blanket, easily transforming a furnace into higher-temperature service.
Quick and Cost-Effective Fix
The CERABOLT System from TFL is a proven money saver! Let’s take a look at the benefits of Cerabolt overlay vs. a module replacement.
Using Cerabolts to overlay an existing lining is cost-effective. On a recent project, we had an opportunity to directly compare the costs of a Cerabolt overlay against the complete replacement of modules to restore a worn lining. The furnace in question was a 42’ long car bottom furnace used for heat treating. The existing lining was made with 12” x 12” x 12”, 2300°F ceramic fiber modules, 9.3 lb. density. Approximately 1,664 sq. ft was being repaired.
For the same amount of repaired area, the Cerabolt overlay option offered the following cost advantages:
- Job duration: 3 shifts, 10 hrs ea.
- Manhours: 150
- Cost: $38/sq. Ft.
- Job duration: 5 shifts, 10 hrs ea.
- Manhours: 300
- Cost: $48/sq. ft.
Minimize Furnace Downtime
As you can see, the Cerabolt overlay option offered a 21% savings over the cost of complete module replacement. Additionally, the furnace downtime was decreased considerably.
