Overview: Electromagnetic Stirring Equipment for Continuous Casting (EMS) is an advanced technology used to improve the solidification structure of metals during the continuous casting process. By applying electromagnetic forces to the molten metal, the stirring promotes uniform mixing, thereby enhancing the internal quality and mechanical properties of the cast products. Key Functions of Electromagnetic Stirring: 1. Improvement of Solidification Structure: EMS can break down coarse dendrites, refine grain structures, and homogenize the distribution of alloy elements. 2. Reduction of Macrosegregation: The stirring action effectively reduces the compositional segregation within the cast billets, leading to higher quality end products. 3. Reduction of Non-Metallic Inclusions: EMS helps non-metallic inclusions float to the surface, decreasing the content of inclusions in the cast products. 4. Reduction of Internal Defects: By promoting better mixing, EMS reduces porosity and looseness, increasing the density and mechanical properties of the cast products. Components of Electromagnetic Stirring Equipment: 1. Electromagnetic Stirrer: Comprising electromagnetic coils and a power supply system, it generates an alternating magnetic field to stir the molten metal. 2. Power Control System: Controls the current and frequency supplied to the electromagnetic stirrer to adjust the stirring intensity and pattern. 3. Cooling System: Cools the electromagnetic coils to prevent overheating during operation. 4. Mounting Brackets: Secure the EMS equipment in the correct position to ensure effective stirring. Major Application Areas: - Steel Industry: Used for electromagnetic stirring in the continuous casting of steel to improve the quality of steel billets. - Non-Ferrous Metals: Applied in the continuous casting processes of aluminum, copper, and other non-ferrous metals to enhance the properties of the cast products. - Foundry Industry: Utilized in sand casting, continuous casting, and other processes to improve the quality of castings. Selection and Usage Considerations: 1. Stirring Frequency and Intensity: Select appropriate stirring frequency and intensity based on the casting process and metal type to achieve optimal stirring effects. 2. Equipment Installation Location: Choose and install the EMS equipment in a location that ensures the electromagnetic field effectively acts on the molten metal. 3. Cooling System Maintenance: Regularly check and maintain the cooling system to ensure the electromagnetic coils do not overheat during operation. 4. Power Control System: Ensure the power control system operates reliably, providing consistent current and frequency. Summary:The introduction and application of continuous casting electromagnetic stirring equipment not only improves the quality of steel, but also promotes the modernization of iron and steel metallurgy process. It is an indispensable advanced technology and equipment in modern casting industry. Disclaimer
