one&time period Configuration&colon

Electromagnetic Stirrer &lparEMS&rpar is frequently utilised on CCM&lparcontinuous casting machine of bloom&solbillet&rpar&comma installed in the mould&comma strand or last&time period Most EMS are mounted outside or inside of the mould&comma which depends on the conditions of your casters&period of time CZPTerized adjustment that you can use Mould-EMS &plus Closing EMS jointly to accomplish a greater metallurgical consequences&time period

two&time period Doing work Basic principle&colon

An inductive Electromagnetic Stirrer is the stator of an asynchronous motor&comma the rotor of which is the liquid main of the continuously solid merchandise in CCM&period of time This stator produces possibly a rotating or a touring magnetic induction subject&comma which induces eddy recent perpendicular to magnetic subject&period of time The stirrer creates mobile magnetic fields&comma which penetrate into the liquid metal&comma and results in eddy current&time period The magnetic induction subject and the eddy recent combine to produce an electro-magnetic power&comma which triggers the stirring motion in the liquid steel&interval

Throughout cooling and solidification of liquid metal&comma columnar dendrites are formed which are oriented together the route of temperature gradient&time period This causes central segregation and inter-columnar cracking when the solid shell is subjected to tensile strains during solidification&time period Electromagnetic stirring of liquid steel facilitates a lot quicker dissipation of superheat and the formation of an equi-axed framework in the forged merchandise&period

Stirring of liquid pool will enhance the inside framework due to much better heat transfer in between solidification front and liquid metal pool&period The equi-axed zone in the forged solution will boost whilst the central segregation will lessen&period of time It will also help in reduction of breakouts during procedure of CCM due to greater dissipation of warmth&time period

There are three varieties of EMS in accordance to installation placement&colon
–Mould Electromagnetic Stirrer&colon M-EMS
–Strand Electromagnetic Stirrer&colon S-EMS
–Closing Electromagnetic Stirrer&colon F-EMS
