The laboratory has spark direct reading spectrometers such as Thermo Fisher ARL8860, Hitachi 0E750, Italian GNR S3, and German Spike SPECTRO MAXx. The ARL8860 equipment detector uses photomultiplier tubes for photoelectric signal conversion and is equipped with multiple channels, which have the characteristics of stability, high accuracy, and a wide range of measurement contents. The Hitachi 0E750, Italian GNR S3, and German Spike SPECTRO MAXx models all use CCD detectors, which have full spectrum detection capabilities, multiple types of testing elements, fast speed, and easy maintenance. The above equipment uses standard samples that match our company's product matrix to draw a large number of working curves before leaving the factory and during installation, covering the entire range of product element content to ensure the accuracy of pre furnace sample and finished product element analysis.
The oxygen and nitrogen content in heat resistant alloys has a critical impact on their performance. These elements can cause defects in steel, such as shrinkage cavities, blowholes, porosity, pinhole segregation, and cracks, while also exerting their unique influences on the material's properties. Therefore, measuring oxygen and nitrogen gases is of great significance. The oxygen, nitrogen, and hydrogen analyzer is a specialized instrument for detecting gas content in steel. Utilizing pulse heating and infrared-thermal conductivity detection technology, it enables the rapid and accurate determination of oxygen, nitrogen, and hydrogen elements in steel, metal powders, non-ferrous metals, and other materials.
The carbon and sulfur content in heat resistant alloys has a critical impact on their mechanical and processing properties. Therefore, determining the carbon and sulfur content in alloy materials is of great significance. The high-frequency infrared carbon-sulfur analyzer and high-speed carbon-sulfur analyzer used by our company can accurately measure the carbon and sulfur content in various alloy materials, with detection limits reaching the PPM level. During routine analysis and testing, the carbon and sulfur detection data from spark direct reading spectrometers can also be calibrated according to analysis standards. This ensures rapid and accurate acquisition of data for routine ladle carbon-sulfur analysis and finished product carbon-sulfur analysis, thereby supporting efficient and high-quality production processes.
