Abstract

PROCESSO, DISPOSITIVO E CIRCUITO PARA DETERMINAçãO DE FALHAS DE SUPERFìCIE, COMO POR EXEMPLO TRINCAS, RUPTURAS E SEMELHANTES, EM UM ROLO DE UM LAMINADOR Um processo, um dispositivo e um circuito servem para determinação de falhas de superfície, como por exemplo trincas, rupturas e semelhantes, em um rolo (2) de um laminador (1), especialmente em rolos de trabalho (2a), que estão montados com rolos de apoio (2b) em colunas de montante (3). Os rolos (2) podem ser testados quanto a falhas em sua posição operacional, na medida em que ondas transversais de ultra-som (4a) produzidas com uma freqüência de cerca de 0,5 - 2 MHz são introduzidas em uma primeira extremidade de rolo (2c) e recebidas em uma segunda extremidade de rolo (2d) e sendo que durante a operação de medição um transmissor de ondas de ultra-som (5) e um receptor de ondas de ultra-som (6) são firmemente pressionados sobre a superfície de rolo (2e) pelo tempo do teste.
