Abstract

"PROCESSO PARA DETECTAR UMA FALHA DE ROLETE EM UM ROLETE DE UMA MáQUINA DE LINGOTAMENTO CONTìNUO". A presente invenção refere-se a um processo de detectar uma falha de rolete em um rolete em uma máquina de lingotamento contínuo, dotada de uma pluralidade de roletes dispostos em uma fileira em relação mutuamente sucessiva e rotativamente suportados em mancais e cujos roletes são previstos para o material produzido na máquina. O processo compreendendo as etapas de: determinar um valor de carga alvo radial exercido pelo material sobre um rolete, medir o valor de carga efetivo sobre pelo menos cada segundo rolete na fileira de roletes, comparar o valor de carga efetivo medido com o valor de carga alvo determinado, detectar uma possível divergência entre o valor de carga efetivo e o valor de carga alvo, e estabelecer a presença de uma falha de rolete no caso de uma divergência deste tipo."PROCESS TO DETECT A ROLLER FAILURE ON A ROLLER OF A CONTINUOUS CASTING MACHINE". The present invention relates to a process of detecting a roller failure in a roller in a continuous casting machine, equipped with a plurality of rollers arranged in a mutually successive relationship and rotatingly supported on bearings and whose rollers are provided for the material produced on the machine. The process comprising the steps of: determining a radial target load value exerted by the material on a roller, measuring the effective load value on at least every second roller in the roller row, comparing the measured effective load value with the load value determined target, detect a possible discrepancy between the actual load value and the target load value, and establish the presence of a roller failure in the event of such a discrepancy.
