金属を採取することができる。When measuring the temperature, when the sampler for temperature measurement is inserted into the molten metal, the molten metal flows through the window 3, so at this time, the thermocouple 11
The temperature of the molten metal can be measured by the molten metal, and when the temperature measuring sampler is pulled from the molten metal, the molten metal can be collected into the sump 2.
しかし、このような従来の側温用サンプラは、1回しか
使用できないのにもかかわらず、熱電対11を用いてお

なものであった。However, such conventional side temperature samplers use thermocouples 11 even though they can only be used once, and require heat-resistant protection for lead wires 13 during manufacturing. It was expensive because it required a process.
そこで、この発明は、このような従来のΔIII温川サ

り、後端はパイプ1内に指向している。As shown in FIG. 1, the temperature measuring light receiving device of the present invention includes a hot water/sink 2 provided at the tip of a support pipe 1 for scooping up molten metal, and a sump 2 for flowing the molten metal into the water reservoir 2. Window 3 and
The window 3 is provided with an aluminum cover 7 that temporarily covers the window 3, and a lid 4 in which a heat-resistant transparent light guide rod 5 such as a silicon body is passed through the hole 6. The rear end is directed into the pipe 1.
そして、支持パイプ1の内面、蓋4の内面、孔6の内面

After that, when the tip reaches the molten metal, the aluminum cover 7 is melted and torn, and the molten metal flows into the sump 2 through the hole 3.

The light enters from the tip of the light guide column 5 through the hole 6, is guided through the pipe 1 and the optical fiber 9 to the optical thermometer IO, and is optically measured.
このとき、先導体体5の先端には、空気が充満された孔
6の空間が存在するから、溶融金属が光導体JP+55
の先端に触れて汚染することはない。At this time, since there is a hole 6 filled with air at the tip of the guide body 5, the molten metal is transferred to the photoconductor JP+55.
Do not touch the tip and contaminate it.
そして、測温用受光共を溶融金属の中から引上げると、
湯溜め2の中に溶融金属を汲取ることができる。Then, when the temperature measurement light receiver is pulled out of the molten metal,
Molten metal can be pumped into the sump 2.

減らすことができる。As explained above, the temperature measurement light receiving device of the present invention does not use an expensive thermocouple made of noble metal in the side temperature sampler, and the assembly process is simplified, so it is inexpensive. Since the cost of consumable parts is low, the cost of measuring the temperature of the molten metal and pumping the molten metal can be significantly reduced.
