The role of electronic computing machines is great
in the operation of blast
furnaces at the same level, all work is highly mechanized and automated.
As we mentioned above, blast furnaces work continuously for 5-10 years. It is
natural to ask the question of how to determine when the blast furnaces will be
repaired. Usually,
the radioactive isotope
66
So is released between the rapidly
decaying areas of the blast furnace wall. Geiger counter ¥ radiation is monitored
during the operation of the furnaces. When a certain thickness of the furnace wall is
burned, a certain amount of
66
So is transferred to the cast iron.
In this case, the
radiation index ¥ decreases. Therefore, the repair time is determined by observing
the meter indicator ¥ radiation.
