Original abstract

Knowledge of temperature distribution in the roll is fundamental aspect in cold rolling. An inverse analytical method has been previously developed to determine interfacial heat flux and surface temperature by measuring the temperature with a thermocouple (fully embedded) at only one point inside the roll. On this basis some pilot mill tests have been performed. The temperature sensor, the calibration procedure and rolling tests at different strip rolling conditions (5%, 10%, 15% and 20%) are described. Results show a good agreement with well-known theoretical models. Moreover the CPU times of the method (around 0.05 s by cycle) enable an online control of the rolling process.

Czech abstract

Znalost tepelného pole ve válci je základní stránka válcování za studena. Byla vyvinuta inverzní analytická metoda pro stanovení tepelného toku mezi prostředími a stanovení povrchové teploty, která využívá termočlánek (zcela zapuštěný ve válci), který měří teplotu v jednom bodu válce. Na tomto základě bylo provedeno pilotní válcování. Práce popisuje teplotu senzoru, kalibrační proces a testy válcování pro různé podmínky při válcování (5%, 10%, 15% a 20%). Výsledky ukazují dobrou shodu s teoretickými modely. Navíc, nízký výpočetní čas (0,05 s/cyklus) dovoluje online kontrolu válcovacího procesu.
