In the fast-paced modern world of metallurgy, the use of stirrers for electromagnetic stirrer (EMS) enhances the quality of steel, productivity, and reduces overall production costs. At Steelopedia, the importance of Industry 4.0 electromagnetically stirring, a revolutionary technology in the continuous casting of alloys, is analyzed. 

 

What is an Electromagnetic Stirrer? 

An electromagnetic stirrer (EMS) is an advanced piece of equipment that has a defined purpose in the casting of metals, more specifically, during the continuous casting of steel, copper, and aluminum alloys. They consist of induction coils, which are static and can produce a rotating alternating magnetic field. Such fields interact mechanically with the superheated conductive alloys of metal. The effects from the EMS apparatus result in the propitious smooth temperature equilibrium across the portion of the molten alloy, its solidification, and further metal structure refinement along with improved overall characteristics. 

How Does Electromagnetic Stirring Operate?  

The main principle behind the operation of EMS is the Lorentz force, which results from applying an induced magnetic field to a conductive fluid that is already in motion. The electromagnetic force instills a sulging movement onto the bath of liquid alloy, which allows for equalization to take place, ensuring that the temperature and composition become consistent.

Installing the EMS system can be done at various points in the process of casting:  

• M-EMS (Mould Electromagnetic Stirrers) mitigates coarse blow holes and inclusions on the surface whilst increasing cross-sectional integrity by augmenting reinforcements electromagnetically in the mould region.  

• S-EMS (Secondary Cooling Zone EMS) improves the grain structure while diminishing internal quality deficiencies such as centre porosity and segregation over internal pores.  

• F-EMS (Final Electromagnetic Stirrers) are used on high-carbon steels and alloy steels in the solidification closeout zone to eliminate centre shrinkage and centre cracking.  

Electromagnetic Stirrers Within The Industry  

Electromagnetic stirrers are critical in the following metallurgical processes:  

• Manufacture of continuous cast billets, blooms, and slabs.  

• Steel, Copper, and Aluminium alloy steel grain refinement.  

• Increase the equiaxed grain formation rate and reduce the centreline segregation.  

• Improvement of casting and surface flaw imperfections.

 

Advantages of Electromagnetic Stirrers for Steel Production

           1. Aspects of the steel production processes are capable of being modernized with EMS systems. Here’s how electromagnetic stirrers benefit the steelmaking process:

           2. Enhanced Product Quality: Dispersion of voids, blowholes, and shrinkage porosity while achieving a more homogeneous metal structure.

           3. Improved Yield: Wastage minimization and output maximization.

           4. Faster Startup & Payback: Reduction in energy expenditures and processing time. Faster EMS systems optimization results in faster stirring.  

           5. Surface Finish Improvement: Reduction of grinding surfacing requirements and the elimination of oscillation mark residuals.

           6. Process Stability: Control of molten steel flow and stable maintenance of a meniscus.

 

Why EMS is the Future of Metallurgy  

Steel manufacturers face growing competition in the global market, thus, the constant demand for high-performance steels and quality drives innovation. Electromagnetic stirrers become the optimal solution for the modernization of casting machines.
