ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light receiving section of a device for optically measuring the temperature of molten metal such as molten steel, and in particular, to eliminating the influence on temperature measurement due to slag floating on the surface. It is configured as follows.
通常、溶鋼の表面はスラグで覆われているためすること
が困難であった。Normally, the surface of molten steel is covered with slag, making it difficult to do so.
そのために、従来より熱電対を用いて測温を行なってい
たが、熱電対は消耗するために、測温ごとに新しい熱電
対と交換しなければならないという問題があった。To this end, thermocouples have conventionally been used to measure temperatures, but there has been a problem in that thermocouples wear out and must be replaced with new thermocouples each time the temperature is measured.
そこで、この発明は、このような従来の測温上の問題点
を解決す゛るために考えられたものであり、次に、図面
によって詳細に説明する。Therefore, the present invention was devised to solve such problems in conventional temperature measurement, and will be described in detail below with reference to the drawings.
