Complete EMS System Configuration

Complete EMS System Configuration
　　EMS consists of coil, electric controller and cooling water system. Electrical controller consists of remote IPC, local control cabinet (PLC/IPC) and frequency inverter cabinet.

　　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 different freq and current. So the best freq 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.
　　Freq arrange shall be widened to choose the best freq.
　　Put EMS lower properly to make magnetic field around meniscus as little as possible to ensure strong magnetic field.
　　1.EMS for Bloom (Round)
　　There are three kinds of EMS according to installation position:
　　·Mould Electromagnetic Stirrer: M-EMS
　　·Strand Electromagnetic Stirrer: S-EMS
　　·Final Electromagnetic Stirrer: F-EMS
　　So far, most of steel plant use M-EMS or M+F-EMS

　　2. Features of EMS for Bloom (Round)
　　一、Mould EMS (M-EMS)
　　EMS inside mould using mould water: EMS is installed inside the mould and uses cooling water system of the mould. It can be operated conveniently with low cost. Stirring freq: 2-8Hz (Refer to Fig.l)
　　EMS inside mould using clean water: EMS is installed inside water jacket of the mould and uses a separate cooling water system. Structure is compact and life is long. Stirring freq: 2-8Hz (Refer to Fig.2)
　　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 sections. Stirring freq:2一5Hz.(Refer to Fig.3)

　　Inner cooling type ems: can be installed inside or out the mould. cramer windings are adopted, which has even magnetic field without polarization. But magnetic leakage is too much with electromagnetic pollution cooling water quality has to be very strict and operation cost is higher. Stirring freq is 1—6Hz
