The invention relates to a method for detecting the carbon content of low-carbon steel, belonging to the field of iron and steel metallurgy. The method cuts a low-carbon steel coil or a low-carbon steel plate on a production site to the size of B5 or A4 paper by cutting; The low carbon steel coils are processed into small samples of 30~40mm × 30~40mm on the sawing machine; welding, welding the small samples to the large-scale production steel samples; washing and grinding, using the triangular clamping of the steel sample washing and grinding machine The large-scale production steel sample is clamped by the machine, and the steel sample washing and grinding machine is started to grind the small sample; for testing, the washed and ground small sample is taken out, and the vacuum direct reading spectrometer is used to analyze the surface of each small sample. Check at least 3 points; compare, compare the detected carbon content results with the standard; judge, if the comparison result is consistent with the standard requirements, the low carbon steel coil is qualified, to solve the carbon content test result in the low carbon steel coil Inaccurate technical issues. |
