    摘要： A measuring method of chromium-free coating film thickness on surface of strip steel comprising selecting two water-soluble chemical substances containing elements P, Ca, Ti, Ba or Sr and not reacting with a chromium-free coating liquid; adding the chemical substances into the chromium-free coating liquid and agitating them to be homogeneous, thereafter, fabricating a reference sample of coating film; using a ray emitted by an off-line film thickness instrument to excite the two water-soluble chemical substances so as to obtain characteristic spectrums to obtain a correction function expression between the measured film thickness and the thickness correction value by fitting; adding the water-soluble chemical substance which has a weak characteristic spectrum into a chromium-free coating liquid, and using the expression to obtain the actual coating film thickness. The method is capable to monitor film thickness with no adverse effect on adhesiveness and corrosion-proof of the coating film.
