Reduce your maintenance, anticipate a longer lifespan and lower life-cycle cost with the right selection of a furnace muffle replacement for your high-temperature furnace operations. Alloy Engineering specializes in the manufacture of OEM and replacement furnace muffles, able to meet specifications for any style make from any manufacturer. When purchasing a replacement furnace muffle, there are at least five key points to consider prior to making a decision.
Muffle replacement can cause major disruptions in the production cycle. The objective is to create a furnace muffle that combines optimal performance with the longest service life to avoid frequent replacement.
We have earned a world-class reputation for manufacturing high-temperature furnace muffles through innovative design and superior fabrication techniques. While we supply muffles in a variety of application-specific configurations, our overall design, when compared to a conventional muffle, not only meets and exceeds performance requirements, a furnace muffle from Alloy Engineering extends component life to provide the longest possible service.
For example, a traditional straight-walled rectangular muffle for a sintering furnace made of 330 alloy would have a service life of about 12-14 months operating at 1120⁰C (2048°F).
However, an Alloy Engineering muffle made of 330 alloy using deep corrugations and welded with inert gas shield arc, could offer a service life of 24 months under the same conditions. For a more detailed breakdown, find the total estimated cost savings here.
When a furnace muffle fails, whether this failure is indicated via dew point readings, discoloration, humping or complete collapse, our engineering team can identify both the cause and a solution for failing furnace muffles—one that meets your individual environmental and processing challenges.
Quality furnace muffle design begins with addressing the specific processing environment. For example, a different alloy incorporated in the replacement furnace muffle can help resist creep at higher temperatures. If humping or collapse was the main cause of failure, our design might include reinforced muffle walls or sides.
Materials selection, welding capabilities and proper corrugation are also key steps to building the right furnace muffle for you.
Every muffle is welded to ASME Section IX procedures by our ASME/AWS Certified welders. Instead of relying on a simple bead of weld, all our welds are prepped to ensure 100% fusion of the base metals used in a furnace muffle manufacture. A better weld helps prevent atmosphere leaks, which helps supply a more controlled atmosphere within the system to help maintain the integrity of the processing chamber, resulting in consistent and predictable production.
Our engineering team evaluates the multiple factors in your specific operation influencing long-term muffle performance. We focus on improving the performance of the replacement furnace ]muffle compared to that supplied by the OEM to stretch out the service life no matter what type of high-temperature, continuous furnace environment it encounters.
Part of the value in having reliable engineering support, compared to simply choosing a catalogue option, is that often the proper solution exceeds a simple part replacement. After conducting a thorough examination, our team can and has offered process recommendations that can lessen the mechanical stresses on the muffle to extend its service life. And of course, a replacement muffle from Alloy Engineering is manufactured to meet your needs based on temperature, atmosphere and production requirements, selecting the appropriate materials from a portfolio of different alloys or special bi-metal composites.
Alloy Engineering furnace muffles are found in all parts of the globe, operating in the harshest of furnace environments. Part of this global penetration is due to our broad range of capabilities to fabricate muffles from 5” to 100” belt widths and 16 gauge to ¾” wall thicknesses.
Our material selection is not limited either, and can incorporate stainless steel, nickel-alloy steel, titanium, aluminum or special bi-metal composites.
