The particular chemical composition of scaffolding coupler is essential, so in most situations, the chemical composition is usually acceptance. Chemical composition also decides the mechanical performance of the scaffolding coupler and this defects occur or possibly not.

For example, if the residual magnesium subject matter in grey iron scaffolding couplers is a lot less than 0. 03%, it has to be bound to be affected the result of spheroidizing undesirable defect. Chemical composition varies between heater time, sampling time investigation test results become furnace, the result is additionally varied by analysis system. Nonferrous alloy coupler towers and special performance conditions of high alloy metallic coupler scaffolding, special surefire and high temperature alloy scaffolding coupler, usually utilize the chemical composition of casting alloy mutually of scaffolding coupler acceptance of technical conditions. To ensure the caliber of coupler scaffolding, scaffolding coupler factory should also be in the deal of production check as well as control the chemical makeup of alloy.
Chemical analysis of constructional scaffolding coupler, generally is usually divided into furnace framework coupler terminal inspection and also finished product inspection. Air conditioner inspection usually adopts thermal analysis, ultrasonic, spectrometry, gasoline rapid analysis method in addition to corresponding equipment, that can check rapidly the principle ingredient in casting alloy liquid, casting alloy taste elements, impurity elements and dissolved gas content in a few momemts.

For example, the energy analysis method, can branch of casting with the thermal analysis of trial continuous cooling curve, determination of carbon in in the bag and carbon equivalent, silicon content, the assessment of that effect of inoculation as well as spheroidized iron liquid; Using X-ray fluorescence spectrometry, can analyse the chemical composition with the sample, the entire practice, from the casting small sample to print out the outcomes of the analysis, few minutes; In hydrogen meter, that oxygen and nitrogen determination meter, can quickly assess hydrogen, oxygen, nitrogen and also other gases dissolved in the actual liquid.
