Abstract
A method for measuring the temperature in a mold by a fiber-optic measurement method and a correspondingly designed mold. For this purpose, light waveguides, through which laser light is conducted, are arranged in grooves in the outside surface of the copper mold plate. The temperature at several measurement points along the measurement fiber is determined by a temperature detection system. In particular, the method makes it possible to achieve much greater local resolution of the temperature measurements than that achieved by thermocouples.
Claims11
A method for measuring temperatures in a mold of a casting machine, the mold having an inside surface exposed to molten metal and an oppositely directed outside surface not exposed to molten metal, the method comprising the steps of:
- measuring the temperature in at least one copper plate of the mold with sensors connected to a temperature detection system, wherein at least one light waveguide fiber, through which laser light is conducted, is used as a sensor;
- arranging grooves parallel to and between cooling channels on the outside surface not exposed to molten metal of the mold's copper plate, wherein each groove portion is arranged parallel to each portion of the cooling channel;
- and
- arranging the at least one light waveguide fiber in a high-grade steel mantel in the grooves in a serpentine manner without intersecting.
A mold for casting of metal, comprising:
- at least one copper mold plate having an inside surface exposed to molten metal, an oppositely directed outside surface not exposed to molten metal, and grooves provided on the outside surface of the copper mold plate so as to be parallel to and between cooling channels on the outside surface, wherein each groove portion is arranged parallel to each portion of the cooling channel;
- and
- light waveguide fibers for temperature measurement arranged in the grooves in a serpentine manner without intersecting.
