This chemical composition of scaffolding coupler is critical, so in most conditions, the chemical composition is usually acceptance. Chemical composition also decides the mechanical performance in the scaffolding coupler and this defects occur or not really.
For example, if the residual magnesium subject matter in grey iron scaffolding couplers is a lot less than 0. 03%, it need to be bound to be affected a result of spheroidizing undesirable defect. Chemical composition varies between heater time, sampling time evaluation test results become air conditioner, the result is also varied by analysis procedure. Nonferrous alloy coupler access and special performance conditions of high alloy metal coupler scaffolding, special cast iron and high temperature metal scaffolding coupler, usually use the chemical composition of casting alloy as you of scaffolding coupler popularity of technical conditions. To ensure the caliber of coupler scaffolding, scaffolding coupler factory should also be in the operation of production check as well as control the chemical makeup of alloy.
Chemical investigation of constructional scaffolding coupler, generally can be divided into furnace podium coupler terminal inspection plus finished product inspection. Air conditioner inspection usually adopts energy analysis, ultrasonic, spectrometry, energy rapid analysis method and corresponding equipment, that can check rapidly the leading ingredient in casting metal liquid, casting alloy test elements, impurity elements and dissolved gas content in some time.
For example, the energy analysis method, can branch of casting from the thermal analysis of test continuous cooling curve, determination of carbon in in the bag and carbon equivalent, silicon written content, the assessment of the actual effect of inoculation as well as spheroidized iron liquid; Implementing X-ray fluorescence spectrometry, can analyse the chemical composition from the sample, the entire process, from the casting sample to print out final results of the analysis, just a few minutes; In hydrogen meter, the oxygen and nitrogen willpower meter, can quickly assess hydrogen, oxygen, nitrogen along with gases dissolved in your liquid.
