Mould Electromagnet Stirrer for Billet

Technical Features of KEMEIDA EMS

A new algorithm has been developed by KEMEIDA and GL electromagnetic field software Co., names AGILD EM stirring algorithm, which uses new strip magnetic field differential integral equation.
This software can design electromagnetic parameters optimized. EMS shall be with high magnetic induction and stirring force. So stirring effect shall be great.
Stirring force can be calculated by this software according to different frequency and current. So the best frequency and current can be provided for user.
Optimized design shall be done for L/D. Iron core length shall be increased properly. So stirring effect shall be improved.
Kemeida has also other software for designing F-EMS to calculate best position of F-EMS.
Kemeida EMS uses low voltage and large current, which can avoid damage of peak voltage to insulation. It shall make reduce current leakage and prolong EMS life.
Frequency arrange shall be widened to choose the best frequency.
Put EMS lower properly to make magnetic field around meniscus as little as possible to ensure strong magnetic field.

The way of installation of M-EMS
 

ccording the different mould structures and requirements, we have three the way of installation as following:

1) EMS inside mould using mould water: EMS is installed inside the mould and uses cooling water system of the mould. If can be operated conveniently with low cost.

2) EMS inside mould using clean water: EMS is installed water jacket of the mould and uses a separate cooling water system. Structure is compact and life is long.

3) EMS outside mould:

EMS is installed outside the mould with separate cooling water system. It is simple to change copper tube, EMS can be used for wide range of section.
