アルミニウムの厚さ

When manufacturing aluminum plates, it is important to keep the plate thickness constant. Micro-Epsilon offers geometrically measuring systems for the determination of thickness and width for cold and hot rolling mills. The distance and profile sensors used operate independently of material or alloy.

コイル直径

The optical optoNCDT ILR length sensor continuously measures the surface of the coil and detects the diameter. By unwinding, the diameter of the coil is reduced, which is detected based on the increasing distance between the coil surface and the sensor.

コイルの巻き出し

In the metal industry, rolled strips are reeled for transportation on coils. In the further processing when coils are unreeled, it is important to know how much material has already been unwound. This task can be easily solved by using an optical optoNCDT ILR length sensor.

コイルのエッジ

Directly before and after the coil it is important to inspect the position and the edge condition of the metal strip. This task can be easily solved using optical optoCONTROL micrometers. If the edge of the coil is within the measuring range during winding or unwinding, the position or the edge structure can be determined from this.

金属ストリップの厚さ測定

When measuring the thickness of metal strips, optical methods based on laser triangulation have numerous advantages compared with other methods. They measure without contact and therefore without wear. Moreover, independently of the condition of the material it is possible to carry out an exact geometrical measurement in relation to the strip surface.

金属ストリップ材のトリミング時でのストリップ幅

Since it is often necessary to trim the strips after the rolling process when producing metal strips in different widths, the two knives can be moved electrically. To maintain the nominal dimension, the distance is measured by differential measurement with laser sensors from Micro-Epsilon. Two optoNCDT sensors are used for this purpose.

圧延ローラ間のギャップ

In rolling operations of metals, plastics or other materials, the distance between the two rollers to one another or between the roller and the bearing surface is the decisive measure. For sensitive processes and high material accuracies, it is important to constantly check the gap so that possible waste is avoided. For this purpose, inductive contacting or non-contacting methods are suitable.

パイプライン検査のための溶接シーム追跡

In pipelines, defective welds are often the reason for a leak. Therefore, the scanCONTROL profile scanner checks the seams on the outside after welding. After manual alignment, the scanner automatically inspects the weld, centering itself on the pipe.

溶接シームのプロファイル

When joining metals, welding robots are often used to automate the joining process of the metals. In the case of visible components, the weld seam must meet certain visual criteria; for example, no weld beads may remain. For this purpose, a laser scanner is installed directly after the welding head. It measures all drawn welds and, if necessary, prompts the robot to make corrections.

プレス前での金属板の重送検知

Before shaped sheets are fed into the press, laser-optical displacement sensors are used, which enable double sheet detection. Two sensors are mounted above and below the continuous sheets and provide a thickness value regardless of the exact position of the sheets.

コイルの直径測定

マイクロエプシロンによるoptoNCDT ILR2250-100シリーズのレーザ距離センサは、位相比較法を用いてコイルを測定します。この測定タスクを行うには、コイルから0.2~10mの距離にコイルの半径を捉える形でセンサーを設置し、コイルまでの距離を連続的に測定します。巻き戻し工程ではスチールロールの直径がどんどん小さくなるため、結果としてコイルとセンサとの距離が大きくなるので、センサがこの距離の変化を確実に捉え、測定値としてRS422シリアルインターフェースを介して製造プロセスの制御に送信します。材料が完全に巻き切れる前に、制御システムを介して早めに警告メッセージを出すこともできるようになりました。

プレスプロセス時におけるシートメタル送り込みの測定

The measurement of the distortion is carried out using several optoNCDT 1420 laser triangulation sensors, which are placed around the metal sheet, either in the tool or on the side of the tool. The arrangement is chosen in such a way that the laser beam measures on the edges of the sheet, which is between the top and bottom of the tool.
