Numerical simulation of electromagnetic braking device for FTSC thin slab mold
In order to study the main factors affecting electromagnetic field distribution of FTSC thin slab funnel mold,by measuring the electromagnetic field pattern distribution of funnel mold,a mathematical model of electro-magnetic field inverse problem of funnel mold electromagnetic braking was constructed,which is based on the elec-tromagnetic theory,and then the electromagnetic braking technology was studied in detail,and the effect of cooling water medium in copper plate water channels on the magnetic induction intensity of the funnel mold was investigated for the first time.The results show that the five pairs of magnetic poles form a geometric magnetic field distribu-tion,which similar to the shape of"ω"on the wide surface of the mold.When the magnetic pole current intensity increases from 300-200 A to 1 100-800 A,the maximum magnetic induction intensity in the mold increases from approximately 70 mT to 200 mT;under the same coil current intensity,the larger the coil turns,the stronger the magnetic field generated;the cooling water medium in the copper plate water channels,which has little influence on the electromagnetic field in the mold.
