摘要
描述了自行设计的电磁软接触圆坯连铸结晶器,给出了相应的三维圆坯连铸结晶器电磁软接触电磁场的数学模型.采用有限元方法对数学模型进行数值求解,在对数值计算结果进行实验验证后,系统地研究三维圆坯连铸结晶器内磁场分布.数值解与实验结果误差小于5%.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.
A very close to realistic production soft-contact EMCC （electromagnetic continuous casting） round billet mold was introduced, and the corresponding three dimensional mathematical model for electromagnetic fields was developed. The mathematical model was numerically solved using finite element method under well-posed conditions. After the validation of numerical results by experiments, the three dimensional distributions of magnetic flux density in the soft-contacting EMCC mold were systematically investigated. The errors between numerical and experimental values are less than 5 percent. The relations between magnetic flux density and all structural and operational parameters are obtained quantitatively, which will provide a theoretical quidance to the design and operation of soft-contacting EMCC round billet mold.
