500A Current Rotating Magnetic Field Inner Mold Installation Position For Steel Billet

High Quality of Mould Electromagnetic Stirrer for Steel Billet

Configuration:

Electromagnetic Stirrer (EMS) is regularly used on CCM(continuous casting machine of bloom/billet), installed in the mould, strand or final. Most EMS are installed outside or inside the mould, which depends on the conditions of your casters. Customerized adjustment that you can use Mould-EMS + Final EMS together to achieve a better metallurgical effects.

Working Principle:

An inductive Electromagnetic Stirrer is the stator of an asynchronous motor, the rotor of which is the liquid core of the continuously cast product in CCM. This stator produces either a rotating or a traveling magnetic induction field, which induces eddy current perpendicular to magnetic field. The stirrer creates mobile magnetic fields, which penetrate into the liquid steel, and creates eddy current. The magnetic induction field and the eddy current combine to create an electro-magnetic force, which causes the stirring motion in the liquid steel. During cooling and solidification of liquid steel, columnar dendrites are formed which are oriented along the direction of temperature gradient. This causes central segregation and inter-columnar cracking when the solid shell is subjected to tensile strains during solidification. Electro magnetic stirring of liquid steel facilitates quicker dissipation of superheat and the formation of an equi-axed structure in the cast product. Stirring of liquid pool will improve the internal structure due to better heat transfer between solidification front and liquid metal pool. The equi-axed zone in the cast product will increase whereas the central segregation will reduce. It will also help in reduction of breakouts during operation of CCM due to better dissipation of heat.

Consist:

EMS consists of coil, electric controller and cooling water system. Electrica l controller consists of remote IPC, local control cabinet (PLC/IPC) and frequency inverter cabinet.

Final Electromagnetic Stirring(FEMS):

It is installed at the freezing terminal of the continuous casting machine and adopt the type of rotating magnetic field. It can choose the low frequency and power frequency to exciting according to the casting blank.

Technical Data:

About Inquiry:

I. There are three kinds of EMS according to installation position:
1. Mold Electromagnetic Stirrer: M-EMS
2. Strand Electromagnetic Stirrer: S-EMS
3. Final Electromagnetic Stirrer: F-EMS

II.Do you need built-in type electromagnetic stirrer or built-out type electromagnetic stirrer?
Mold electromagnetic stirrer(M-EMS) is divided into built-in and built-out type according to its relative position with crystallizer/casting mold.

IV.Do you need purchase complete equipment or only need stirrer?
complete equipment is including stirrer and control part equipment.
