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.
