建立了大方坯连铸结晶器电磁搅拌条件下电磁场及钢液流场数学模型，开发了相应的Visual Cast仿真软件，并应用软件模拟分析了大方坯连铸结晶器内磁场、电磁力分布及双侧孔浸入式水口条件下结晶器内钢液流场的分布特征。结果表明，结晶器内磁场分布均匀，并沿横断面水平旋转，电磁力的旋转周期为磁场旋转周期的一半。电磁搅拌改变了结晶器内流场形态，减小回流区和冲击深度，有利于促进钢液中非金属夹杂物上浮排除，提高大方坯洁净度。
In order to simulate the magnetic flux density, electromagnetic stirring force and fluid flow in bloom continuous casting mold, a mathematical model is set up and the software of Visual Cast has been developed. Numerical simulation results show that the rotary magnetic field in mold is uniform and its period is two times electromagnetic force. The flow pattern greatly varies and the circumfluence region as well as the jet impinging depth decreases with the effect of electromagnetic stirring, which will decrease the quantity of nonmetallic inclusion in bloom.
