Die steel is a steel type used for manufacturing cold die, hot forging die, die and other dies. Moulds are the main processing tools for the production of parts in industrial sectors such as machinery manufacturing, radios, motors, electrical products, etc. The quality of the mold directly affects the quality of the stamping processing technology, the accuracy of the product and the production cost, but in addition to relying on reasonable structural design and processing accuracy, the quality and life of the mold are also mainly affected by the mold material and heat treatment. The processing materials of the mold need to be verified by X-ray fluorescence analysis handheld X-ray Orientation Analyzer.

Material composition identification (PMI) plays an important role in manufacturing, petrochemical and consumer product manufacturing industries. In the manufacturing process, not only must the correct metals and alloys be used in appropriate locations, but also to ensure that the material composition is not biased, such as no heavy metal pollution. X-ray fluorescence (XRF) analysis is highly efficient for identifying component components. A simple method helps to confirm whether the metals and alloys used are correct.

Handheld spectrometer X-ray Orientation Analyzer is a portable instrument that only needs to prepare a small amount of samples to quickly provide test results. The identification of alloy composition is one of the most common XRF applications: X-ray Orientation Analyzer using a hand-held beam splitter can usually identify alloy varieties in a short time of 1 second to 2 seconds. When using a handheld X-ray fluorescence spectrometer (X-ray Orientation Analyzer) to determine the composition of materials, the three important factors to be considered are as follows

01 Material composition

The handheld spectrometer X-ray Orientation Analyzer can quantitatively analyze more than 90% of the elements in the periodic table: from magnesium to heavier elements. These measurable elements cover most of the elements used in commercial alloys. Figure 1 shows a representative 1 detection limit for commonly used alloying elements. Based on the obtained material composition information, the XRF analyzer's detection capability can obtain aluminum alloy, stainless steel, chromium-molybdenum alloy, multi-pipe and flange materials, really? ? Many so-called "superalloys" based on alloys, bronze alloys, various other copper alloys, solder, titanium alloys, tool steels, nickel and cobalt elements can be brand matched.

The handheld spectrometer X-ray Orientation Analyzer cannot directly detect elements lighter than magnesium. Undetectable elements include alloying elements such as lithium, beryllium, and carbon. These elements include different applications.

The operation scheme of the handheld spectrometer X-ray Orientation Analyzer includes: (1) X-ray emission; (2) X-ray return to the detector; X-ray fluorescence is a surface detection technology. In some light alloys, such as aluminum alloys, XRF technology can only detect a depth of hundreds of microns below the sample surface. Some major metals, such as iron, copper or XRF technology, can detect samples with a depth of no more than 100 μm. For dense materials, such as gold and lead, only a depth of tens of microns below the sample surface can be detected. This means that in the case of inspection using x-ray fluorescence technology, if the surface of the material does not correctly represent the composition of the entire material, reliable inspection data cannot be obtained. Surface contamination, such as paint, protective layer, coating, analysis results may be greatly distorted. Similarly, the materials and dirt remaining on the surface after sandblasting, sandblasting, and grinding may affect the judgment result of the material composition. Therefore, be sure to clean the sample before using XRF technology to check the sample.

The handheld spectrometer X-ray Orientation Analyzer uses a low-power x-ray tube. The emitted x-rays and returned x-rays are of low power, and the analyzer must be brought close to the sample when measuring. Ideally, the sample directly contacts the measuring window of the analyzer. If the sample has a complex geometry, it is difficult to detect, but the main body of the analyzer is narrow and can be as close as possible to the bevel sample. For example, flanges welded to pipes at 90 degrees.

03X-ray Orientation Analyzer sample surface temperature

The physical properties of x-rays used in XRF analysis techniques hardly change with changes in sample temperature. In addition, the design goal of the analysis device is not to be affected by changes in environmental conditions, and always exert reliable measurement performance. When the analyzer is operated in the temperature range of -10 ° C to 50 ° C, thermal drift and performance degradation will not occur.

The X-ray Orientation Analyzer analyzer is not modified, and the sample can be measured normally when the sample temperature reaches about 100 ° C. When the temperature is exceeded, the polypropylene fiber film that is part of the analyzer window is easily damaged. Provide users with high-temperature washers that can be used in high-temperature inspections. The high-temperature gasket contains a polyimide window, and the analyzer can measure samples up to 315 ° C.
