Spark Direct Reading Spectrometer

Used in steel casting inspection and operation experience.

The pouring process is a critical stage in the production of steel castings. If not properly managed, it can lead to defects and non-compliant products. Therefore, strict adherence to established procedures during the pouring process is essential for producing high-quality steel castings.

Accurate testing equipment is vital to ensure the quality of the final product. The QL-5800 Spark Direct Reading Spectrometer is specifically designed for this purpose. It enables precise analysis of chemical elements in materials, offering both qualitative and quantitative detection in a fast and convenient manner.

This spectrometer is widely used across various industries such as metallurgy, foundry, machinery, metal processing, automotive manufacturing, non-ferrous metals, aerospace, defense, and chemicals. It plays a key role in production process control, laboratory analysis, and finished product inspection, making it an effective tool for maintaining product quality.

Steel castings account for approximately 12% of total casting output in recent years, significantly impacting the development of the entire casting industry. Proper planning and execution at every stage of production are crucial to improving the quality of steel castings and promoting the growth of the industry as a whole.

Casting Steel Casting Operation Experience

Before the pouring process begins, thorough preparation is necessary to ensure smooth operations. This includes:

• Keeping the pouring area clean to maintain safety and efficiency.
• Inspecting the ladle’s condition, its drying and preheating status, and the reliability of the transport and tilting mechanisms.
• Understanding the type of alloy being used, estimating the number of castings and the required amount of molten metal to avoid shortages.

Controlling the pouring temperature and speed is essential for achieving high-quality results. For carbon steel castings, the ideal pouring temperature typically ranges between 1540°C and 1580°C. The casting speed should be adjusted based on the solidification requirements—faster for simultaneous solidification and slower for sequential solidification.

During the pouring process, certain operational guidelines must be followed. For example, when casting large or medium-sized steel pieces, allow the molten metal to settle in the ladle for 1–2 minutes before pouring. After casting, remove any pressure iron or box cards promptly to reduce shrinkage resistance and prevent cracks in the final product.
