この発明は、錫鍍金鋼板上の防錆油量をオンラインで全
長に亘って計測するための装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for online measuring the amount of rust preventive oil on a tin-plated steel plate over its entire length.
錫鍍金鋼板上の防錆油塗油量は、防錆性能上要求される
ための必要最小限の塗油量と、錫鍍金鋼板加工工程にお
ける脱脂性より要求される最大限の塗油量の両面を満足
させる必要がある。The amount of rust preventive oil applied on the tin-plated steel sheet is determined by the minimum amount of oil required for rust prevention performance and the maximum amount of oil required for degreasing in the process of processing the tin-plated steel sheet. It is necessary to satisfy both sides.

を２時間に１回の割合で定期的に実施し、錫鋼板の塗油
量の測定を行なっていた。The conventional method for measuring the amount of applied oil is to cut out a sample of a tin steel plate coated with anti-corrosion oil, spread the anti-rust oil adhering to the surface of the sampling plate off-line as a monomolecular film on a water film, and measure its area. This was carried out by measuring the amount of oil applied to the tin steel plate, and this was carried out regularly once every two hours to measure the amount of oil applied to the tin steel plate.
しかし、上記のような防錆油塗油量の測定方法では、■
錫鍍金鋼板上の全長の塗油量が連続的に測定できない、
■塗油量の実際値の把握に時間を要する、■サンプルを
採取するために試材を取り出さなければならない、など
の問題点がある。また塗油量を変更する毎に、この煩雑
な作業を行い、塗油装置の調節を行う必要がある。However, with the above method of measuring the amount of anti-rust oil applied,
The amount of oil applied over the entire length of a tin-plated steel plate cannot be measured continuously.
There are problems such as ■It takes time to determine the actual value of the amount of oil applied, and ■It is necessary to take out the specimen to collect the sample. Moreover, each time the amount of oil applied is changed, it is necessary to perform this complicated work and adjust the oil application device.
この発明は、上記のような課題を解決するためになされ

らなることをその特徴とする。For this reason, the present invention provides a first film thickness measurement device in a tin plating line, which is disposed upstream of the oil coating device in order to measure the thickness of the chromic acid film adhering to the surface of the tin-plated steel sheet. a second film thickness measuring device disposed on the downstream side of the line of the oil coating device to measure the total thickness of the chromic acid coating and the oil coating, and a travel length detection device for detecting the distance traveled by the steel plate. It is characterized by comprising a device and a signal processing device which inputs detection signals from the above devices and calculates the thickness of the oil coating or the amount of oil applied on the tin-plated steel plate.

膜の厚さを測定するようにしたものである。Generally, this device reflects a laser beam on a measurement object having a coating, splits the reflected light into multiple beams using a beam slitter, and detects the amount of light that has passed through an analyzer for each beam using a light amount detector. The device measures the coating thickness based on this detected amount, and is known as an apparatus that can measure the thickness of extremely thin coatings with a thickness of about 10 to 100 people. However, tin-plated steel sheets have a transparent romic acid coating on their surfaces.
Even with the above-mentioned high-speed ellipsometer, it is not possible to accurately measure only the thickness of the oil coating formed on such a transparent romic acid coating. Therefore, in the present invention, the thickness of the chromic acid film is first measured on the upstream side of the line of the oil application equipment, and then the total film thickness of the chromic acid film and the oil application film is measured on the downstream side of the line of the oil application equipment. The thickness of the oil film is measured based on the difference in thickness.

積あたりの塗油量を計算する。To explain this specifically based on the configuration of the present invention, a first film thickness measuring device placed upstream of the line of the oil application device measures the thickness of the transparent romic acid coating attached to the tin-plated steel plate. A second film thickness measuring device disposed downstream of the oil coating device continuously measures the sum of the chromic acid film thickness and the coating oil film thickness using a high-speed ellipsometer. The travel length detection device counts the number of pulses from a pulse transmitter attached to the priddle roll and measures the distance the steel plate travels within a unit time. The signal processing device converts the detection values of the chromic acid film thickness measurement positions by the second film thickness measurement device and the first film thickness measurement device into the values of the coil from the traveling length detection device. Tracked by travel length signal,
It is corrected as a detection signal from the same location on the steel plate, and the difference between the rain detection values is calculated as the oil film thickness. Furthermore, when determining the amount of oil applied, the amount of oil applied per unit area of the steel plate is calculated using a predetermined specific gravity.
