Abstract
A method for detecting a roller failure at a roller in a continuous casting machine having a plurality of rollers arranged in a row and rotatably supported in bearings for transporting material produced in the machine involves determining a radial target load value exerted by the material on a roller, measuring the actual load value on at least each second roller in the row of rollers, comparing the measured actual load value with the determined target load value, detecting a possible divergence between the actual load value and the target load value, and establishing the presence of a roller failure upon detection of such divergence.

A method for detecting a roller failure at a roller in a continuous casting machine, the continuous casting machine having a plurality of rollers arranged for transporting material produced in the machine, the rollers being arranged in a row one after another and rotatably supported in bearings, the method comprising:
- determining a target load value exerted by the material on a roller;
- measuring an actual load value on at least each second roller in the row of rollers;
- comparing the measured actual load value with the determined target load value;
- detecting a divergence between the actual load value and the target load value;
- and
- establishing a roller failure upon detecting a divergence between the actual load value and the target load value.
A method for detecting a roller failure in a continuous casting machine that is comprised of a row of rollers supported in bearings and arranged one after another for transporting material produced in the machine, the method comprising:
- measuring an actual radial load value exerted by the material being transported on one of the rollers;
- comparing the measured actual radial load value with a target radial load value;
- detecting a divergence between the measured actual radial load value and the target radial load value;
- and
- determining that a failure of the roller exists upon detecting a divergence between the actual radial load value and the target radial load value.
