Electromagnetic Stirring for metal casting process

Annulus EMS For semisolid molding Application

1. Experimental stirring of aluminum and magnesium alloys

2. Semi-solid forming study

3. Experimental research of crystallization process

4. Die Casting

5. Metal foam molding

6. Metal purification stirring
Advanced Feature of Continuous semi-solid casting process for

aluminum alloy


1. Electromagnetic stirring do not pollute the liquid aluminum as no physically direct contact. It benefit for melting high purity aluminum and aluminum alloy.

2. It solved the uniformity problem of alloy composition, can get good effect compare with artificial stirring.

3. It don’t destroy oxide layer mixing, reducing new oxide residue producing, reducing the burning rate.

4. Stirring directions and stirring intensity can be adjusted.

5. One-time investment, lower cost, save energy, improved production efficiency.

6. Easy operation, convenient maintenance


Electromagnetic Stirring result


1. Reduced content of slag

2. Reduced central shrinkage

3. Eliminating macro segregation

4. Increased equiaxed crystal ratio

5. Improved solidification structure
