Abstract
【解決手段】光ファイバにより溶融金属中で温度を測定するための方法において、光ファイバ(2)の浸漬端を、支持体(6)により支持され且つ溶融金属消耗性である第1の消耗性本体(1)により案内し、光ファイバ(2)の浸漬端を、消耗性本体(1)と共に溶融金属に少なくとも1回浸漬し、前記支持体(6)の少なくとも部分的な消耗後に、前記第1の前記消耗性本体(1)を前記支持体(6)から取り外し、次いで第2の消耗性本体(2)と交換し、前記光ファイバ(2)を前記第2の消耗性本体(1)を通して送る。
【選択図】図1
Description
消耗性本体が鉄(又は鉄鋼、鋳鉄)よりも高い溶融温度を有し、溶融鉄に不溶性ならば有利である。とくに、本体が鋳砂、耐火セメント、及び結合フライアッシュの少なくとも一種から製作されると有利である。材料は接着剤により結合できる。鋳砂、耐火セメント、及び結合フライアッシュは約600℃から約1700℃の温度範囲の溶融金属において使用するのに適する。これらの材料は耐熱性が非常に高い。これらの材料から形成した本体は溶融金属中で、材料の粒子同士の結合を分解する浸食により分解する。この過程は浸漬端から始まって長手軸線方向、つまり光ファイバの軸線に沿って進行する。光ファイバは石英から製作するのが有利である。
