| Popis: | The Superconducting Electromagnetic Iron Separator (SEIS) based on paraffin wax vacuum pressure impregnation (VPI) technology was developed to remove magnetic impurities from coal. The superconducting coil was wound by Cu/NbTi wires. The inner and outer diameter of the coil are 928 mm and 1022 mm respectively. The height of the coil is 355 mm. The magnet generates a 3 T central field at 165 A of operating current. There are three SEIS devices that have been manufactured and tested. All the design requirements are achieved by the first device. However, the others can’t be charged to the design current in 20 min, which is a requirement of coal handing port. This paper presents the details of the VPI process and the charging tests. The excitation characteristics of three SEIS devices are shown in the results. |
