| 摘 要： | 用数学模拟对马钢一钢厂圆坯连铸结晶器(断面尺寸为φ450mm)电磁搅拌过程进行了研究,找出变化规律,确定合理的工艺参数,优化结晶器流场.电磁搅拌过程的计算结果表明:磁场强度随搅拌频率减小、搅拌电流增大而增大;电流强度不改变磁场分布;在结晶器高度方向上磁场分布呈现中间大两端小的特征,流场在搅拌力作用下更趋于合理.最佳搅拌工艺参数为:搅拌电流350A,频率2Hz. |

| Abstract: | Electromagnetic stirring process for the round billet mould(450 mm in diameter)in No.1 Steelmaking Plant of Maanshan Steel in China was analyzed by using mathematical simulation.Orderliness was found out in order to optimize flow path in the round billet mould and make certain reasonable casting parameters.Computational results of electromagnetic stirring process indicated that the magnetic field in- tensity increases with the stirring frequency decreased and the stirring electric current increased.The elec- tric current intensity does not change magnetic field distribution.The characteristic of magnetic field along the mould vertical direction is strong in the middle and weak at the end of the mould.The optimized pro- cessing parameters are the stirring electric current of 350 A and the stirring frequency of 2 Hz. |
