Study of Thermal Conductance in a Strip-Roll System
摘要
The paper describes an experimental investigation carried out on a semi-industrial prototype of regenerative roll quench to determine the thermal contact conductance (TCC) between a roll and a moving strip. The quantitative infrared thermograpy allows the temperature mapping of the strip while the angular evolution of the roll temperature is obtained by means of thermocouples connected to a wireless telemetry DAS. A thermal model allows the TCC determination. Typical results emphasize the effect of some parameters such as the velocity, temperature and tensile strength of the strip.
