Innovative ThermoOptical Measuring Devices (TOM) for high-temperature testing of refractories

摘要

Within the scope of the EnerTHERM project, a new generation of ThermoOptical measuring techniques has been developed for establishing the high-temperature properties of refractory materials. The new methods offer the respective prerequisites in terms of adequate measuring volume, a defined atmosphere and defined temperatures. They establish and document the thermo-physical and thermo-mechanical material properties of relevance to the use of refractories: thermal-shock and thermal-cycling resistance, thermal diffusiv-ity and conductivity, heat capacity, thermal expansion, emissivity, Young's moduli, creep resistance, high-temperature strength and corrosion resistance. In particular, they were designed to provide input variables for FE simulations of high-temperature processes. All this serves to facilitate the more closely targeted design of new thermal processes and the selection of appropriate materials for them. Initial successful measurements performed on the new TOM systems underscore their potential for use in the development of energy efficient thermal processes.
