在可实现振动、水冷及拉坯的连铸模拟装置上，采用双条型磁极，分别用低熔点Pb-Sn-Bi合金和硅油模拟钢液和保护渣，对连铸结晶器内的液态金属的流动特性进行了实验研究．研究结果表明：双条型磁极的作用使连铸结晶器内的液态金属中产生了环形电流，能有效地抑制水口出流速度，消除和削弱水口出流对初生坯壳的冲刷；能够有效地抑制弯月面波动．但当磁场强度增大到一定程度时，磁场的作用效果增加不明显．
In the continuous casting simulation device that can realize vibration, water cooling and casting, the double-type magnetic pole is used to simulate molten steel and mold flux with low-melting point Pb-Sn-Bi alloy and silicone oil respectively, The flow characteristics of the experimental study. The results show that the effect of the double-pole magnetic pole produces a ring current in the liquid metal in the continuous casting mold, which can effectively restrain the outflow velocity of the nozzle and eliminate or weaken the outflow of the nozzle to the primary blank shell. Suppress meniscus fluctuations. However, when the magnetic field strength increases to a certain extent, the effect of the magnetic field increases little.
