摘　　要：为了研究影响FTSC薄板坯漏斗形结晶器内电磁场分布的主要因素,通过实测结晶器电磁场场型分布,基于电磁理论构建了漏斗形结晶器电磁制动电磁场反问题数学模型,进而对电磁制动技术进行了详细的研究,并首次研究了铜板水缝内冷却水介质对结晶器内电磁场的影响。结果表明,5对磁极在结晶器内宽面上形成类似于“ω”字形状的几何磁场分布;线圈电流强度从200~300 A增加到800~1100 A时,结晶器内磁感应强度最大值从70 mT增加到200 mT;线圈电流强度相同条件下,线圈匝数越大,产生的磁场越强;铜板水缝内冷却水介质对结晶器内电磁场影响较小。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 electromagnetic field inverse problem of funnel mold electromagnetic braking was constructed,which is based on the electromagnetic 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 distribution,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 1100-800 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.
