| The furnace bottom is compacted in one
operation, from the furnace deck, using a vibrator plate equipped
with two pneumatic eccentric vibrators. The vibrator plate, custom
designed to fit within one inch (25 mm) of the floor diameter ensuring
even and full vibration, is lowered by hoist. Floor vibration is accomplished
in about 12 minutes with no worker entering the confined space of
the furnace and risking exposure to hazardous dust.
 Conventional
vibration requires workers to enter the furnace and can take more
than one hour, depending on the size of the furnace.
