Description: A forge or smelter requires constant supply of high-quality insulation because it is needed to ensure the safety and operability of its high-temp appliances. The base material of high temp insulation may vary depending on its chemical structure and its grade. Being aware of such variation is important when buying new insulation for high-temp appliances.
Any industries that require the use of high level of heat in their production or processing jobs will mostly require constant supply of high temp insulation. In any industrial facilities that use appliances such as kiln, furnace and hearth, a material that reduces the passage of heat will ensure that those appliances will always be safe to use and that they will have longer lifespan. This insulation is needed because it protects the components of those appliances from extreme heat that is developed when they are being operated. When it breaks due to age or any other accidents, the appliances that use it must not be used until they get replacement for it because without insulation, they will malfunction and may become too dangerous to use.
In a forge or smelting factory, high-temperature insulation is used as the internal lining of smelting appliances. This insulation is expected to be capable to resist temperature that can be as high as 3,500°C. The most commonly used material for making insulation is ceramic, although it is also possible to use a mixture of ceramic and metal. Various ceramic materials that are often used for this purpose include alumina, silicon carbide, dolomite, and magnesite.
Different materials with different grades have different level of resistance to different level of heat. Ceramic material of the standard grade, for example, may be able to deal with heat that doesn’t exceed 2000°F. Paying attention to the type of the material as well as its grade is thus important when buying new insulation. In certain circumstances, the insulation material might be expected to be resistant not only to extreme heat, but also to chemical attack in the form of oxidation and reduction. This feature should also be taken into consideration when getting new insulation if resistance to chemicals is deemed important.
