The invention relates to a method for making a martensitic steel spectrometer control sample. The martensitic steel forging material sample is selected, a whole sample is used, and 10 small samples are processed with a sawing machine, according to the needs of the production quantity; Analyze the composition of the block sample to determine the range of element composition; set the parameters of the remelting furnace for induction heating and centrifugal casting, put the sample into the remelting furnace, and smelt and cast according to the set procedure; After adding treatment, carry out the content detection of element components at different levels. According to the principle of standard sample determination and statistical methods, the element content value of the successful control sample is calibrated. By this method, the martensitic steel DIN1.4122 spectrometer is used to ensure the control sample. The need for elemental analysis of steelmaking can improve the measurement accuracy of the chemical composition of DIN1.4122 steel. |
