NOVELTY - The electromagnetic casting apparatus has a connecting element (15) which is connected to the heat-resisting element (7). The silicon ingot (6) is produced by using a transportable plasma arc torch (10) as an auxiliary heat source when silicon raw material (5) is supplied from raw material input hole in upper portion of chamber (1). The electrode (20) of the transfer plasma arc torch is connected to the heat-resisting element. The heat-resisting element is downwardly moved when the silicon ingot is grown.    USE - Electromagnetic casting apparatus for producing silicon ingot used for silicon wafer of solar cell.    ADVANTAGE - The direct contact of electrode of the transfer plasma arc torch with silicon ingot can be prevented so that the crack and contamination of the silicon ingot can be prevented efficiently. Hence, high quality silicon ingot can be ensured. The investment cost of the silicon ingot can be reduced.    DETAILED DESCRIPTION - The heat-resisting element and fetch unit (18) are connected with the connecting element for moving the heat-resisting element to top and bottom. The insulating layer (19) is positioned between the heat-resisting element and connecting element for electrical insulation. The connecting element is provided with two connecting portions connected to the heat-resisting element. A cooling unit is equipped in the connecting element for cooling the connecting element. The height (h) of the heat-resisting element is set to 300 to 2000 mm. The heat-resisting element is provided with the heat resistance base metal portion whose top surface is contacted with the silicon ingot, and refractory metal portion linked with heat resistance base metal portion. The electrode of the transfer plasma arc torch is connected to the heat resistance base metal portion and refractory metal portion. The heat resistance base metal portion is formed of carbon or graphite. The refractory metal portion is formed of molybdenum, tungsten or stainless steel.
