Method and device for the contactless determination of at least one property of an at least partially melted endless strand

Abstract

The present invention relates to a method for contactless determination of at least one property of an at least partially melted quasi-endless strand during a casting process of the quasi-endless strand, which cools down within a cooling zone, allowing successive hardening of the quasi-endless strand, comprising at least the following steps: Emitting a first signal, in particular a first radar signal, in the form of radiation by an emission device, in particular a radar emission device, Generating a second signal, in particular a second radar signal, at least partly by an interaction of the first signal with a region of the quasi-endless strand, receiving the second signal by a reception device, in particular by a reception device for radar signals, determining at least one property of the quasi-endless strand on the basis of the second signal, wherein at least the step of interacting takes place within the cooling zone or upstream of the cooling zone (K), in particular immediately after exit from a mold. The present invention further relates to a device for casting a material, in particular a metal, into a quasi-endless strand in the context of a continuous casting process and for contactless determination of at least one property of the at least partially molten quasi-endless strand during casting of the quasi-endless strand, comprising a mold adapted to form said quasi-endless strand, a cooling zone in which said quasi-endless strand cools down, whereby successive hardening of said quasi-endless strand is enabled, an emission device, in particular a radar transmitter, adapted to emit emitting a first signal in the form of radiation, in particular as a first radar signal, a reception device, in particular a radar receiver, which is arranged to receive a second signal, in particular a second radar signal, whereby the second signal being generated at least partially by interaction of the first signal with a region of the quasi-endless strand within in the cooling zone or upstream of the cooling zone (K), in particular immediately after exit from a mold, a data processing unit arranged to determine at least one property of the quasi-endless strand on the basis of the second signal. According to the invention, a corresponding use is also provided.
