And 0.4~0.6 respectively for the induction coil with round crosssection and rectangular cross-section; The magnetic flux density of coil made with round pipe was nonuniform, especially near the inner wall of coil turns that caused a fluctuation of electromagnetic pressure on the surface of liquid metal and had a bad effect for forming a sample with uniform cross-section and smooth surface; The system of screen and restraint magnetic field not only had an efficient effect on restraining the electromagnetic stirring and stablizing meniscus, also caused the conecial periphery of melt to be vertical; The position of top and S/L interface of melt had a direct effect on the meniscus shape. The meniscus profile varied from cone-shaped through column to cucurbituceous shape with the increase of top height or decrease of S/L interface.
对圆形截面、矩形截面感应圈来说D/H分别取0.7~1.1,0.4~0.6较为理想;对多匝感应圈来说,在匝间处存在漏磁,易引起熔体表面起伏不平,这种现象在用圆铜管绕制的感应圈中较为明显;屏蔽—抑流系统的加入可以消除电磁搅拌,使熔体稳定性增强,同时可使形态呈锥形的熔体侧面变得垂直成为理想形态;熔体上液面、固/液界面的选位直接影响成型形态,上液面升高,熔体形态经历锥形→柱形→葫芦形的转化,固/液界面下降则经历锥形→葫芦形的转变。
