| 摘要 |
The invention relates to a process comprising the cooling and comminuting of molten calcium carbide, wherein a molten stream of calcium carbide is tapped off from a furnace at 1900 DEG to 2100 DEG C., cooled and comminuted. More particularly, the molten calcium carbide is initially comminuted into droplets and the droplets are cooled to less than 200 DEG C. The process can be carried out with the aid of an apparatus comprised of a heatable or coolable feed duct, a nozzle for comminuting the molten stream, and a series of fluidized bed cooling zones. |
