【考案の詳細な説明】 産業上の利用分野 本考案は、連続鋳造で鋳造された鋳片の幅を測定するた
めに設けられた幅計を校正するための基準片に関するも
のである。TECHNICAL FIELD The present invention relates to a reference piece for calibrating a width meter provided to measure the width of a slab cast by continuous casting.
従来の技術 従来、連続鋳造で製造される鋳片の幅を測定する方法と
しては、鋳片が高温であることから間接的な測定方法、
即ち光学的な方法によるものが一般的であった。Conventional technology Conventionally, as a method for measuring the width of a slab produced by continuous casting, an indirect measurement method because the slab is at a high temperature,
That is, the optical method is generally used.
この方法は第２図に示すように製造される幅Ｗなる鋳片
の両側にL1の間隔を保ち２台の光マイクロ検出器を置
き、その反射光を検出して鋳片側面と検出器との距離L2
を測定し、また他方の鋳片とマイクロ検出器との距離L3
も同様な方法で測定する。In this method, two optical micro-detectors are placed on both sides of a slab with a width W as shown in Fig. 2 with a space of L1 and the reflected light is detected to detect the side surface of the slab and the detector. Distance of L2
And the distance L3 between the other slab and the microdetector.
Is measured in the same way.
更に測定したそれぞれの距離L2,L3を演算器に入力し、
（１）式によって鋳片幅Ｗを求めている。Furthermore, input each measured distance L2, L3 to the calculator,
The slab width W is calculated by the equation (1).
Ｗ＝L1−（L2＋L3） （１） 次に、幅計の校正方法としては、測定器の測定範囲内の
任意の３点をチェックする、いわゆる３点チェックが一
般的に採用されているが、この方法によれば測定した３
点がリニアにまた測定範囲（スパン）を満足していれば
校正良しと判断できる。W = L1− (L2 + L3) (1) Next, a so-called three-point check, which checks any three points within the measuring range of the measuring instrument, is generally adopted as a method for calibrating the width meter. Measured by this method 3
If the points are linear and satisfy the measurement range (span), it can be judged that the calibration is good.
従って校正を行うためには、この任意の３点を決めるも
のが必要となる。そこでこの３点を決めるものとして校
正用基準片を３種類準備する必要があった。この３種類

大幅付近、最小幅付近とその中間にある幅を校正するた
めにそれぞれ間隔の異なる校正用基準片を３種類用意
し、これを用い順次検定していた。Therefore, in order to calibrate, it is necessary to determine these three arbitrary points. Therefore, it was necessary to prepare three types of calibration reference pieces to determine these three points. These three types of calibration reference strips were prepared by calibrating three points within the measuring range of the width meter, that is, near the maximum width of the cast piece, near the minimum width of the cast piece, and in the middle thereof, by using calibration reference pieces with different intervals. Different types were prepared and sequentially tested.
考案が解決しようとする問題点 この校正用基準片を使い検出器の校正を行うときには基
準片が３種類あるため、校正時には何回となく繰り返し
この基準片を検出器の間に置き換える必要があり、校正
に長時間要していた。Problems to be solved by the invention Since there are three kinds of reference pieces when calibrating the detector using this reference piece for calibration, it is necessary to repeatedly replace this reference piece between the detectors during calibration. , It took a long time to calibrate.
また、この基準片を据え付けるときには、光マイクロ検
出器から放れたレーザ光軸が校正用基準片に垂直に当た
るように連続鋳造ラインに設けられている校正用基準片
設置台に設置しなければならない。従って３点測定する
たびに、基準片設置による位置のズレが生じ、校正精度
に大きく影響を及ぼしていた。Further, when this reference piece is installed, it must be installed on the calibration reference piece installation table provided in the continuous casting line so that the laser optical axis emitted from the photomicrodetector hits the calibration reference piece perpendicularly. Therefore, every time the measurement is performed at three points, a positional deviation occurs due to the installation of the reference piece, which greatly affects the calibration accuracy.
以上のように３点チェックに用いる校正用基準片の対峙
間隔の異なる基準片が３種類用意されているため、基準
片の置き換えに時間を要し、しかもセット位置にバラツ
キが生じこれによって校正精度に悪影響を及ぼしてい
た。As described above, since there are three types of reference pieces with different facing intervals of the calibration reference pieces used for the three-point check, it takes time to replace the reference pieces, and the set position varies, which causes the calibration accuracy. Had a negative effect on.
