【摘要】 电磁软接触是电磁连铸技术的关键环节之一。本文在实验结果验证的基础上,用数值模拟方法系统地研究了三维圆坯连铸结晶器内磁场分布,分别考察了结晶器结构参数,钢液液面高度,电流强度等参数对结晶器内磁场分布的影响。定量地得到了结晶器内磁感应强度随各种结构参数和操作参数变化的规律。为电磁软接触连铸圆坯结晶器的设计和实际操作提供了理论依据。
【Abstract】 The soft—contact electromagnetic continuous casting is one of the key techniques in continuous casting.Based on the software validation by experimental results,the three dimensional distributions of magnetic flux density in soft-contacting electromagnetic continuous casting(EMCC) are systematically investigated numerically.Influences of many factors on magnetic flux density,such as the structure parameters of mold,free surface heights of liquid steel,electrical current densities,are considered. Relations between magnetic flux density and all parameters are obtained quantitatively.All these results can act as theoretical quid to the designing of the mold and its practical operating.
