| 摘要 |
The invention relates to a process and to a device for purifying molten metallurgical silicon, which is obtained from quartz and coal in a reduction furnace (1). For this purpose, reactive gases are introduced into the molten silicon still in the reduction furnace (1) via channels (13, 14) in the bottom region of the electric arc furnace (1), so that an additional final purification apparatus is unnecessary. <IMAGE>
