HEAT-FLUX COMPUTATION FROM MEASURED-TEMPERATURE HISTORIES DURING HOT ROLLING

Original language description

Due to the long service life of work rolls it is very important to follow the thermal load, but it is very difficult to measure it. One option for computing this thermal load is to measure the temperature and to study the thermal load through the heat flux. A unique work roll was made for testing different process conditions, such as rolling velocity, roll cooling, skin cooling and reduction. This work roll was tested on a real, hot-rolling, continuous pilot line. Two types of temperature sensors were embedded in the work roll in order to measure the temperature and these gave very detailed information about the development of the temperature inside the work roll. A time-dependent heat flux was computed using an inverse heat-conduction task with a detailed numerical model. The surface-temperature history was also obtained from this computational model. These boundary conditions give detailed information about the influence of different process conditions and allow a computation of the temperature field in the work roll. The paper describes the measuring equipment, details of the used temperature sensors, the inverse heat-conduction task for computing the thermal-surface boundary conditions and the results obtained from hot-rolling conditions.
