【産業上の利用分野】[Industrial applications]

この考案は、鋼板の断面プロフィルを精度良く連続的に測定するため、幅方向 の板厚分布を、一端側から他端側まで連続的に正確に計測することができるプロ フィルメータに関するものである。 The present invention relates to a profile meter capable of continuously and accurately measuring a plate thickness distribution in a width direction from one end side to the other end side, since a cross-sectional profile of a steel plate is accurately and continuously measured. ..

【従来の技術】[Prior Art]

鋼板においては、鋼ストリップ圧延工程などにおける種々の要件から、鋼板の 幅方向の両端部側近傍に、エッジ近傍残留応力の影響から、C反りが発生する問 題がある。図3は鋼板のC反りを説明した図で、同図に示すように鋼板6の幅方 向の両端側近傍に反りがみられる。 コイル状の鋼板(鋼ストリップ)を切断したシート状の鋼板の断面プロフィル を測定するために、鋼板の板厚分布を、幅方向の一端側から他端側まで連続的に 計測する場合、従来から接触式の板厚計測器が使用されている。しかしながら、 このようなC反りが発生すると、鋼板の幅方向の両端部側近傍においては、板厚 を正確に計測できない問題が生じる。すなわち、従来の板厚計測器により行われ る計測は、板厚を直角に計測することからなっているが、図3に示すように幅方 向中央部が板厚方向に垂直に測定出来たとしても、端部側近傍はC反りの影響か ら板厚を斜めに測定することとなる。このようなC反りの影響は、板厚の薄い鋼 板ほど大きく、厚さ2.3mm 程度のもので10μm ほどの誤差となることがある。従 って、鋼板の幅方向端部においては、板厚を正確に計測できないという問題があ った。 In a steel sheet, due to various requirements in the steel strip rolling process and the like, there is a problem that C warpage occurs near the both ends in the width direction of the steel sheet due to the effect of residual stress near the edges. FIG. 3 is a diagram for explaining the C-warp of the steel sheet. As shown in the figure, the warp is seen near both ends of the steel sheet 6 in the width direction. In order to measure the cross-sectional profile of a sheet-shaped steel sheet obtained by cutting a coil-shaped steel sheet (steel strip), when measuring the thickness distribution of the steel sheet continuously from one end side to the other end side in the width direction, A contact type thickness gauge is used. However, when such C warpage occurs, a problem arises in that the plate thickness cannot be accurately measured in the vicinity of both end portions in the width direction of the steel plate. That is, the measurement performed by the conventional plate thickness measuring device consists of measuring the plate thickness at a right angle, but as shown in Fig. 3, the central part in the width direction could be measured perpendicularly to the plate thickness direction. Even in this case, the thickness of the plate near the end is measured obliquely due to the influence of C warpage. The influence of C warpage is greater for steel plates with a smaller thickness, and an error of about 10 μm may occur for a steel plate with a thickness of about 2.3 mm. Therefore, there is a problem that the plate thickness cannot be accurately measured at the widthwise end of the steel plate.

【0003】 その対策として、図4および図5に示すように、鋼板6の端部にチャック14に よってチャッキングを行って鋼板の反りを防止あるいは許容範囲内に緩和し、し かして計測器9のセンサが鋼板6の表面に対して直角になるように配置して計測 することが行われている。As a countermeasure against this, as shown in FIGS. 4 and 5, chucking is applied to the end of the steel plate 6 by a chuck 14 to prevent or reduce the warp of the steel plate within an allowable range. The sensor of the container 9 is arranged so as to be perpendicular to the surface of the steel plate 6 for measurement.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、チャック14によってチャッキングを行った場合には、センサが 入るだけの最小限の隙間が必要であることから、この方法によっても、C反りの 影響を完全に防止することは不可能であった。 However, when chucking is performed by the chuck 14, a minimum gap for the sensor to enter is required, and therefore even with this method, it is impossible to completely prevent the influence of C warpage. It was

【0005】 従って、この考案の目的は、特に幅方向両端部において、従来正確に計測する ことが困難であった、C反りの発生した鋼板の幅方向の板厚分布を、一端側から 他端側まで連続的に正確に計測し、鋼板の断面プロフィルを精度良く求めること ができるプロフィルメータを提供することにある。Therefore, an object of the present invention is to obtain the widthwise thickness distribution of a C-warped steel sheet, which has been difficult to measure accurately in the widthwise both ends, from one end side to the other end. The purpose of the present invention is to provide a profile meter that can accurately measure the cross-sectional profile of a steel sheet with accurate measurements continuously up to the side.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するために、この考案においては、鋼板の長さ方向の両端部を 支持して前記鋼板を彎曲させ、彎曲させた前記鋼板を固定するための鋼板固定機 構と、固定された前記鋼板の幅方向の一端側から他端側まで移動して前記鋼板の 板厚分布を計測するための計測器と、前記計測器を移動させるための計測器移動 機構とからなることに特徴を有するものである。 In order to achieve the above object, in the present invention, a steel plate fixing mechanism for supporting both ends of the steel plate in the longitudinal direction to bend the steel plate, and fixing the bent steel plate, is fixed. It is characterized by comprising a measuring device for moving the one side to the other side in the width direction of the steel plate to measure the plate thickness distribution of the steel plate, and a measuring device moving mechanism for moving the measuring device.

【作用】[Action]

被測定鋼板の長さ方向の一端部を固定用チャックで支持し、次いで鋼板を、C 反りに反するL反りが与えられるように所定の曲率で曲げ、そして鋼板の長さ方 向の他端部を固定用チャックによって支持する。このように、鋼板を彎曲して固 定することにより、鋼板の幅方向両端部近傍に発生していたC反りが除去あるい は許容される範囲まで緩和される。そして、このように鋼板の幅方向両端部のC 反りが無くなった状態で、鋼板の幅方向の一端側から他端側まで計測器を移動さ せて連続的に板厚を計測する。これにより、鋼板の一端側から他端側までの計測 誤差は、測定精度範囲以下に押さえられる。鋼板に与えるL反りの曲率は、鋼板 の品質に応じて適宜対応すればよい。 One end of the steel plate to be measured in the length direction is supported by a fixing chuck, and then the steel plate is bent with a predetermined curvature so that an L warp that is opposite to the C warp is given, and the other end of the steel plate in the length direction is bent. Is supported by a fixing chuck. In this way, by bending and fixing the steel sheet, the C warpage that has occurred in the vicinity of both ends in the width direction of the steel sheet is relaxed or relaxed to an allowable range. Then, in the state where the C warps at both ends in the width direction of the steel sheet are eliminated in this manner, the measuring instrument is moved from one end side to the other end side in the width direction of the steel sheet to continuously measure the plate thickness. As a result, the measurement error from one end side to the other end side of the steel sheet is suppressed within the measurement accuracy range. The curvature of the L warp given to the steel plate may be appropriately adjusted depending on the quality of the steel plate.
