Induction furnace for high temperature operation

摘要

An induction furnace capable of operation at temperatures of over 3100° C. has a cooling assembly (60), which is selectively mounted to an upper end of the furnace wall (76). The cooling assembly includes a dome and a lifting mechanism (80), mounted to the dome, which raises a cap (16) of the furnace slightly, allowing hot gases from the hot zone to mix with cooler gas in the dome.
