结合软接触结晶器连铸过程的准三维电磁场数值模拟和实验室中锡等金属的软接触结晶器连铸实验,研究了电磁场频率、铸坯电物性、感应圈电流等对铸坯电磁力和表面电磁压力的作用关系,给出了部分理论计算和实验室连铸实验所得的数学模型- 研究表明,软接触结晶器连铸中,铸坯表面的电磁力与电磁场频率成对数抛物型函数关系,与感应圈电流成抛物型函数关系,铸坯表面的振痕深度为普通连铸的10 % ,并磁感应强度越高则振痕越浅,其无量纲平均深度与无量纲磁感应强度成误差补函数关系
Combined with the quasi-three-dimensional electromagnetic field numerical simulation of soft contact mold continuous casting process and the continuous casting experiment of soft contact mold of tin and other metals in the laboratory, the effects of electromagnetic field frequency, electrical properties of billet, Surface electromagnetic pressure of the relationship between the role of some theoretical calculations and laboratory continuous casting experiments obtained mathematical model - studies have shown that the soft contact mold continuous casting, slab surface electromagnetic force and electromagnetic field frequency parabolic function Relationship, and the induction coil current into a parabolic function, the surface of the slab vibration mark depth of 10% of the ordinary continuous casting, and the higher the magnetic induction intensity, the shallower the indentation, the dimensionless average depth and the dimensionless magnetic induction error Correction function
