到目前为止,在用现有工艺连续铸造铸锭时,还不能消除铸锭表面缺陷和组织不均匀性。高质量表面和组织均匀的铸锭可以采用原理上新的连续铸造方法,即在电磁场中使铸锭成型的连铸方法来生产。电磁力作用在位于感应圈交变磁场中的液体金属上。电磁力是由于金属中诱起的涡流与感应器磁场相互作用而产生的。磁场强度的轴向分力同液体金属中的感应电流相互作用,形成向着与液体金属表面垂直的任一点上的力。这个力系所造成的电磁压
Until now, continuous casting of ingots with existing processes has not been able to eliminate ingot surface defects and structural inhomogeneities. High-quality surface and homogenous ingots can be produced using a new continuous casting method, a continuous casting method of forming ingots in an electromagnetic field. Electromagnetic force is applied to the liquid metal in the alternating magnetic field of the induction coil. Electromagnetic force is due to metal induced vortex and inductor magnetic field interaction arising. The axial component of the magnetic field strength interacts with the induced current in the liquid metal to form a force at any point perpendicular to the liquid metal surface. This force is caused by the electromagnetic pressure
