【発明の詳細な説明】
工業溶融炉に於て、溶融物の内容如何を問わずその液面
を測定し、常に一定しベルを保持するように溶融する技
術は困難とされて１７する。この難点）として考えられ
るのは、炉内雰囲気とし）う特５３１苛酷な條件のもと
で構成される各材料の材質に於て耐熱、強度、及び通電
性の秀れたもの力〈要求されるからである。DETAILED DESCRIPTION OF THE INVENTION In an industrial melting furnace, it is considered difficult to measure the liquid level of the melt regardless of its contents and to maintain the melting level at a constant level17. This difficulty may be due to the fact that each material used in the furnace atmosphere must have excellent heat resistance, strength, and electrical conductivity under severe conditions. This is because that.
従来この必要條件を充すものとして、Ｂｕｓ ３０４、
ＳｕＳ ３１０及びチタン棒を使用して０たカイ、腐角
虫力（烈しく通常５〜６時間の使用で廃棄してし）たの
で半永久的に使用出来る検知棒が望まれてし）だ。Conventionally, Bus 304,
I used a SuS 310 and a titanium rod and had no problems with the power of rotten hornworms (I usually discarded them after 5 to 6 hours of use), so I wanted a detection rod that could be used semi-permanently.
上記のような欠点を補うものとして、炭イし珪素の煉瓦
を検知棒として使用した所、殆ど腐蝕されずに約３ケ月
の寿命があった。To compensate for the above-mentioned drawbacks, a carbonized silicon brick was used as a detection rod, and it had a lifespan of about 3 months with almost no corrosion.
従来から市販されているｓｈｏ耐大物は固くて強い煉瓦
と考えられており、別の用途として電気炉の抵抗発熱体
としてその通電性が認められて来たが、加熱炉の湯面測
定検知棒として電極棒に流れる微弱電流が約２０ｓｍＡ
と適当な数値である為、採用したものである。Traditionally, commercially available sho-durable bricks are considered to be hard and strong bricks, and their electrical conductivity has been recognized as another use as a resistance heating element in electric furnaces. The weak current flowing through the electrode rod is approximately 20smA.
It was chosen because it is an appropriate value.
炭化珪素質検知棒は、金属溶融炉と云う高温雰囲気にも
耐久性があり、溶融金属内への浸漬も充分耐えうる。更
に湯液面の測定に必要な電気伝導性も兼ね備えていて、
最適の検知棒である。The silicon carbide detection rod is durable even in the high-temperature atmosphere of a metal melting furnace, and can withstand being immersed in molten metal. It also has the electrical conductivity necessary for measuring the level of hot water and liquid.
This is the best detection stick.
欠点として云えば、機械的強度が弱く、小さな衝撃力で
も破損され易い点である。しかし高温内で測定する液面
針としては何等支障がない。The drawback is that it has low mechanical strength and is easily damaged by even a small impact force. However, there is no problem in using it as a liquid level needle for measuring in high temperatures.
