Nanjing Kirin testing equipment solves steel quality problems in foundry companies
Hunan Iron and Steel Co., Ltd. has been a loyal old customer of Nanjing Kirin Instrument Group for more than ten years. Starting from the ordinary five major element analyzers , a few years ago, it introduced a set of QL-5800A direct-reading spectrometers to detect steel materials. Multiple element content. Recently purchased a metallographic microscope to detect the depth of the decarburized layer of steel bars (GB / T224-1987), grain size detection, detection of non-metallic inclusions in steel, segregation detection of chemical components in steel, etc. Ferrite, pearlite, tempered martensite should not appear on the base circle, and product quality control has been greatly improved.
Metallographic microscope is a microscope specially used to observe the metallographic structure of opaque objects such as metals and minerals. These opaque objects cannot be observed in ordinary transmitted light microscopes, so the main difference between metallographic and ordinary microscopes is that the former is illuminated by reflected light, while the latter is illuminated by transmitted light. In a metallurgical microscope, the illumination beam is emitted from the direction of the objective lens to the surface of the object under observation, reflected by the object surface, and returned to the objective lens for imaging.
Hunan Iron and Steel Co., Ltd. is a joint-stock private steel company. Its main products are high-efficiency continuous casting slabs and steel bars. It adopts refining technology outside the furnace and new high-efficiency continuous casting technology. It is equipped with Nanjing Kirin QL-5800A direct-reading spectrometer and infrared carbon and sulfur. Metallographic microscope detection equipment such as analyzers and multi-element analyzers, and production processes have achieved enterprise quality and quantity leap.
