Embodiment Construction

[0043] exist Figure 1a An embodiment according to the invention of a detector 11 is shown in . The substantially square base body of the detector 11 can be seen, which is rounded into an arc at the upper and lower ends. Arranged in the detector 11 are four slots 4 , in which an optical waveguide (optical fiber) or fiber optic sensor 2 is arranged in each case. Furthermore, a measurement point 3 is shown at which the temperature can be determined. For example, the detector 11 can be installed in a groove in the side of the mold copper plate facing away from the melt, so that the optical waveguide 2 is oriented in the direction of the melt. In this case, the detector 11 is installed in such a way that the optical waveguide 2 is in direct contact with the copper plate and is arranged in the direction of the melt between the water cooling of the copper plate and the melt. The shown detector 11 can also have other geometries as long as it fits into the groove of the mold copper ...

Abstract

The invention discloses a method for measuring the casting liquid level in a mold by means of a sensor for detecting the temperature in a fiber optic manner, which sensor is arranged in the mold copper plate at the level of the casting liquid level superior. Furthermore, the invention includes corresponding detectors. Arranged in this detector is an optical waveguide which, via a suitable temperature evaluation system, allows simple and reliable temperature monitoring at the level of the casting liquid level and with high spatial resolution. The exact height of the casting liquid level can then be deduced by means of the temperature detected by the probe. Furthermore, the shape of the casting liquid wave can be determined, from which other parameters of the casting process can be derived.

Description

technical field [0001] The invention shows a method for carrying out casting liquids in a crystallizer (Kokille) by means of one or more measuring fibers (Messfaser) and / or by means of a probe (Sonde) for acquiring the temperature in a fiber-optic manner Surface measurement (Gieβspiegelmessung), the detector is arranged in the mold copper plate at the height of the casting liquid level (Gieβspiegel). The exact height of the casting liquid level can be deduced by means of the temperature obtained by means of a sensor for detecting the temperature by fiber optics. Furthermore, the invention includes corresponding detectors. Background technique [0002] Known and usual methods for determining the height of the casting liquid level use radioactive particles (Partikel), which are introduced into the mold, wherein the radiation emitted at different heights of the mold is measured, whereby, Infer the height of the casting liquid level. In order to improve the measurement it is ...
