Chemical analysis of constructional scaffolding coupler, generally can be divided into furnace scaffolding coupler terminal inspection and finished product inspection. Furnace inspection usually adopts thermal analysis, ultrasonic, spectrometry, gas rapid analysis method and corresponding equipment, that can check rapidly the main ingredient in casting alloy liquid, casting alloy sample elements, impurity elements and dissolved gas content in a few minutes.
For example, the thermal analysis method, can branch of casting of the thermal analysis of sample continuous cooling curve, determination of carbon in cast iron and carbon equivalent, silicon content, the assessment of the effect of inoculation and spheroidized iron liquid; Using X-ray fluorescence spectrometry, can analyse the chemical composition of the sample, the entire process, from the casting sample to print out the results of the analysis, only a few minutes; In hydrogen meter, the oxygen and nitrogen determination meter, can quickly analyze hydrogen, oxygen, nitrogen and other gases dissolved in the liquid.
