Companies that manufacture parts for the automotive industry have to produce products that have very high quality. There can be no defective parts delivered to the factory, and, of course, the automotive companies want the lowest price, fastest delivery and a record of the quality tests.

In this issue focusing on new and emerging technologies, we shall speak to recent advances in the relatively old field of pyrometry. There is little information on the invention and development of pyrometers compared to better-known instruments. Common problems that often made pyrometers inapplicable in many situations now have convenient answers.

The following article discusses how recent advancements in noncontact IR temperature measurement not only help induction heat treaters optimize their production processes and business results, but also enable them to meet industry standards defining guidelines for final product quality and reliability.

High-emissivity coating systems have long been recognized as products that can improve energy efficiency and product quality when applied to the refractory linings of industrial furnaces. Such products have been available for over two decades. However, the limited service temperature of some of them, loss of coating in service due to thermal expansion mismatches between the coating and the substrate, and misapplication have prevented these energy-saving products from being widely accepted.
