3 Method summary

The drill cuttings form a block-shaped sample was pressed by high frequency fusion machine with argon protection device will melt, and after centrifugal casting, rapid release To the aqueous medium to be cooled to achieve white pig iron phase change transition, milled or car prepared as a sample for analysis. Application of photoemission spectroscopy measurements.

4 Equipment

4.1 Optical Emission Spectrometer. task analysis should be used to meet the required high-precision instruments. 4.2 Pressure junction devices. 4.3 with argon gas protection devices and temperature probe high-frequency fusion machine. 4.4 Sample processing equipment. lathe or milling machine.

5 treated sample

5.1 Preparation of the sample According to GB/T 20066-2006 in 8.3.2 performed. 5.2 Preparation and processing of samples Weigh 30g ~ 40g by 5.1 Preparation of the sample, the pressure junction device (4.2) after pressure form pieces into the crucible, and set the high frequency fusion machine (4.3) of the parameters (see Appendix A) and melt, after casting is completed as soon as the sample was cast molded into an aqueous medium quenching to white Port of. Ensure sample homogeneity, no shrinkage and cracks. In principle, the use of photoemission spectroscopy analysis of the sample, must be able to ensure that the sample excitation excitation aperture table completely covered in order to ensure ......
