Mold Level in a mold by a fiber optic measuring method

The invention provides a method for Mold Level in a mold by means of fiber-optic temperature probes for the detection, which are disposed in the mold copper plate at the level of the meniscus,. The invention further comprises corresponding probes. In these probes, optical fibers are arranged, which allow by a suitable temperature evaluation system, a simple and reliable and highly spatially resolved temperature monitoring at the level of the meniscus. Using the temperatures determined by the probes can then be closed to the exact height of the meniscus. Furthermore, the shape of the Giesspiegelwelle can be determined, thereby further parameters of the casting process are accessible.
