【摘要】 本文阐述了对结晶器电磁搅拌(M-EMS)最佳运行工作参数的调控,通过测试结晶器铜管中不同频率下的扭矩值确定最佳频率;通过控制保护浇注时弯月面附近的磁感应强度来确定工作电流。结合首钢小方坯连铸结晶器电磁搅拌技术的生产应用情况,阐述了M-EMS对铸坯质量的作用机理,分析了铸坯表面质量与内部质量的提高。更多还原

【Abstract】 The rules of controlling the best running parameters of Mould Electromagnetic (M-EMS) have been expounded. The best running frequency has been decided through testing the torque in the copper mould under different frequency. The running currents have been established by controlling the magnetic induction intensity nearby the meniscus when protection casting. The mechanism of M-EMS effecting on the strand quality has been expounded. According to the M-EMS practice of Shougang, it has analyzed the improvement of strand surface and inner quality.更多还原
