Furnace Insulation Module Type FIM General Information ZIRCAR Ceramics’ Furnace Insulation Modules Type FIM are engineered, pre-assembled insulation systems that provide superior performance in rapid-cycle low-mass furnace applications. FIM Furnace Insulation Modules enable OEM Thermal Process Equipment Manufacturers as well as End User Customers to solve their most unique and challenging furnace chamber applications. FIM Modules are designed and manufactured of a layered and reinforced system of premium grade ZIRCAR Ceramics fibrous ceramic insulation materials encased in an industrial grade shell. 1700°C (3100°F) rated FIM systems incorporate a reinforced hotface layer of ZIRCAR Ceramics’ Alumina Type SALI - with some applications as high as 1740°C (3164°F) - In Air. 1800°C (3272°F) rated FIM systems use a ZIRCAR Ceramics’ Alumina Type SALI-2 hot face layer -with a maximum application temperature of 1825°C (3317°F)- In Air. As FIM Modules are custom designed and built to help customers reach their own specific rapid cycle furnace performance objectives, the exact insulation layering and element configurations along with the FIM shell design all incorporate time-tested features. In general, the hot face (Alumina Type SALI-2 or SALI ) is installed in relatively small panels fully reinforced and supported by fine grain dense ceramic hardware. This installation technique provides for long life during rapid cycling operation as each panel will expand and contract independant of its neighbor - eliminating much of the crack propogation typical in monolithic installations. With the further utilization of two additional insulation layers an essential temperature gradient is set up within the insulation system minimizing the possibility of overheating of the fibrous insulation. All three insulation layers are encased and supported by an outer shell of a Refractory Hardboard. A welded frame of high grade steel surrounds, supports and protects the entire insulation package. In many FIM systems Heating Element Holders, Element Straps and Clamps, Terminal Boards, Hearth Systems and Thermocouple Ports are provided. MoSi2 Heating Elements and appropriate Thermocouples are offerred as well. Our Documents Directory on www.zircarceramics.com provides technical papers and promotional articles on the construction and use of FIM Furnace Insulation Modules. Experienced Technical Sales and Design Staff are available to work wth you and exchange useful information to help you achieve your Furnace Insulation Module objectives. The words of an old furnace builder go something like this: “we make furnaces to sell.” What this means is that many furnace builders simply cut corners on both the materials and the designs they build into their furnaces -so they can compete with each other. ZIRCAR Ceramics’ Furnace Insulation Modules Type FIM have proven time and time again that using the highest performance furnace insulation material in the right way will always lead to the realization of Cost-Effective High Performance. The images and graphics on the following pages are intended to illustrate some of the design concepts and construction techniques used in the FIM Module system. Availability of the FIM System is also discussed. The data presented herein is intended to help the user in determining the appropriateness of this material for their application.

Furnace Insulation Module Type FIM Construction and Scaleability The “accessories roadmap” below shows some of the basic multi-layer insulation design concepts and dense ceramic hardware used in the manufacture of an FIM Module. As an FIM’s hotface layer is reinforced, the weight of this layer, plus the weight of the additional insulation layers are supported by the rugged exterior shell, FIM chambers quite large in size are in successful operation. Large FIM Furnace Insulation Modules Many large FIM Modules are in operation today including: 30”W x 30”L x 26”T Chamber 1700oC Front...

These complete units require only the addition of a protective furnace enclosure and power supply, with temperature controller, to build a complete rapid cycle furnace. Easy to use, FIMs facilitate rapid furnace construction and use components that are easily replaced. Thermocouples and heating elements are available separately. ZIRCAR Ceramics can work with you to source all of the components required to help you build a furnace that solves your unique requirements. Furnace Insulation Module Type FIM Suggested Applications Research and prototype furnace construction. Production furnaces...
