잉곳 제조용 MCZ 초전도자석
Superconducting Magnet for MCZ Growing
DRY Type (1,600mm)
Overview
This is the magnet required to produce ingots, a key material in making silicon wafers. It can implement a magnetic Horizontal Field, which is necessary to grow large-diameter Ingot uniformly.
In addition, the maintenance and management costs are less than 1/50 compared to existing phase conduction magnets. And also, the existing silicon wafer production facilities have been improved more effectively, reducing the production cost of lngots in large diameters.
