Description

technical field

[0001] The invention relates to a measuring solution for measuring the content of metal elements in stainless steel. Background technique

[0002] At present, in the material recycling industry, in order to identify the nature of metal materials, the traditional method is to use magnets or files to distinguish whether it is "iron" or "steel". This extremely primitive method cannot be used for accurate measurement, so many high-temperature alloys and precious metal materials are treated as waste, resulting in a waste of resources. The analytical chemical reagents or instrumental analysis used in the existing metallurgical furnace analysis require special instruments and equipment or reagents, which are expensive and complicated to operate, which limits their application. Contents of the invention

[0003] In order to overcome the deficiencies of the existing stainless steel chemical composition determination method or imprecise, or high cost, complex operat...
