摘 要:

以經(jīng)典電磁場理論為依據(jù),利用有限元軟件ANSYS建立了電磁軟接觸連鑄高頻磁場計算的數(shù)學物理模型。用小線圈法實測了線圈內(nèi)磁感應(yīng)強度的分布,并將實測值與計算值進行比較,驗證了模型的有效性。通過計算,分析了割縫結(jié)晶器內(nèi)磁感應(yīng)強度分布的不均勻性以及感應(yīng)線圈匝間距對結(jié)晶器內(nèi)磁感應(yīng)強度分布的影響。結(jié)果表明:切縫對結(jié)晶器中半徑小于25 mm范圍的影響很小,使接近結(jié)晶器壁處圓周上磁感應(yīng)強度分布的不均勻性較大;減小線圈匝間距可以提高結(jié)晶器內(nèi)磁感應(yīng)強度,線圈匝間距以5~10 mm為宜。

Abstract:Based on electromagnetism theory, a physical and mathematical model of electromagnetic continuous casting was developed through ANSYS software. The distribution of magnetic induction density (B) in the coil was measured through the little coil method. By comparing the measured value with the calculated results, the validity of calculating the electromagnetic field through the model was proved. The ununiformity of B distribution in slit mould was analyzed. The results show that the effect of slit on the B distribution in the area with radius smaller than 25 mm is unconspicuous, and the ununiformity of B distribution in the area close to the mould wall is much remarkable. The effect of distance between coil circles on the B distribution was also studied. The results show that the magnetic induction density increases by decreasing the distance between coil circles, and the better distance between cow circles is 5−10 mm.
