摘 要:The voltage was recorded to investigate the influence of the static magnetic field on droplet evolution during the magnetically controlled electroslag remelting(MC-ESR) process. MC-ESR experiments were carried out under different remelting current, and transverse static magnetic fields(TSMF) of 85 mT, 130 mT and 160 mT were superimposed.Statistical work was performed to obtain the quantitative data of the droplets. The ASPEX Explorer was utilized to investigate the inclusions evolution of GCr15 ingots. The number of the droplets was 31 in 20 s during the traditional ESR process and reached 50 and 51 under the MC-ESR process with the TSMF of 85 mT and 130 mT, respectively. When compared the traditional ESR process with the MC-ESR process, the inclusions amount reduced 67%.
