Spark Direct Reading Spectrometer Used in steel casting inspection and operation experience During the pouring process, which is a critical stage in the production of steel castings, proper execution is essential to ensure the quality of the final product. If the process is not carefully managed, it can lead to defects or even failed castings. To maintain high-quality standards, accurate testing equipment is crucial. The QL-5800 Spark Direct Reading Spectrometer from Nanjing Kirin Scientific Instrument Group is specifically designed for this purpose. This advanced device enables precise chemical element analysis in materials, offering both qualitative and quantitative detection with speed and convenience. It's widely used across various industries such as metallurgy, foundry, machinery, automotive, aerospace, and more for process control and finished product inspection. Steel castings make up approximately 12% of total casting output in recent years, playing a significant role in the development of the entire casting industry. Proper planning and execution in the production of steel castings are essential to improve overall quality and drive industry growth. Before pouring, companies must carry out thorough preparations to ensure smooth operations. This includes cleaning the site, checking the ladle condition, and understanding the alloy type and required metal weight to avoid shortages. Controlling the pouring temperature and speed is vital. For carbon steel, a typical range is between 1540°C and 1580°C. The casting speed should be adjusted based on the solidification requirements—faster for simultaneous solidification, slower for sequential solidification. Pouring procedures also require strict adherence. For large and medium-sized castings, molten steel should be allowed to settle in the ladle for 1–2 minutes before pouring. After casting, pressure iron and box cards should be removed promptly to reduce shrinkage resistance and prevent cracks.
