Refractory Products Imaging with Infrared Thermography

Infrared thermography is a type of infrared imaging science that detects radiation in the infrared range of the electromagnetic spectrum. For users of refractory products, this type of imaging is ideal for producing images of radiation that may be present in refractory materials. Infrared radiation is emitted by every object according to its temperature, and thermography makes it possible to gather images of refractory mortar and other objects with or without visible illumination. The amount of the radiation that is emitted by an object obviously increases with temperature, so thermography can allow one to see variations in temperature. When viewed using this technology, warm objects stand out well against cooler backgrounds.

Thermal imaging has a lot of uses—from power lines maintenance to locating overheating in refractory materials. Discovering this overheating can be the first sign of equipment failure and can eliminate potential hazards to both users, as well as other people who may be in the building or vicinity. When these materials become faulty, technicians can see their thermal signatures and find out if they have heat leaks.

Thermography cameras use specialized focal plane arrays that respond to the longer wavelengths of infrared. These arrays are commonly InSb, InGaAs, HgCdTe or QWIP focal plane arrays. Since these cameras are often very expensive, most users of refractory products rely on companies to come on site and perform the thermal imaging on a consultant basis. There is usually no need for users to purchase a camera themselves.

TFL, Inc. is able to come to your site and perform infrared thermography on your refractory mortar or other refractory materials. We can create a visual picture and a report that covers a wide area so that a comparison of refractory performance is easily made. Our experienced technicians are able to find high temperature deteriorating components prior to failure, which is ideal for components that are inaccessible or too hazardous for other means of observation. This thermography is a non-destructive test and is useful for finding defects in shafts and other metal components.
