Summary:Method and apparatus for continuously sensing and monitoring the conditions of tensed flexible endless metallic casting belts (12,14) and their insulative coatings in a continuous metal casting machine. The flatness of a casting belt (12, 14) is continuously monitored and thereby also the condition of its thermal protective coating. One or more non-contacting eddy-current sensing probes (36, 38) are placed in proximity to the reverse coolant side of a belt (12, 14) for sensing and measuring the distance of the belt from the probe to reveal irregularities in the flatness of the belt while it travels past the probe. A deficiency of insulative belt coating can cause variations in belt flatness during casting. By monitoring such variations an operator of the continuous casting machine is alerted that the coating needs to be retouched or replaced without interrupting the casting process. Or such monitoring can alert the operator that the belt (12, 14) has become inherently not flat.
