the
the burning-through of the furnace wall and the leakage of
iron liquid, which means a serious accident. The adoption
of isotopic tracing technology can reduce the shutdown period
of the furnace and guarantee its safety operation. Likewise,
knowing well the movement and distribution of the gas current
the in the shaft furnace is of extreme importance to/reinforcement of the shaft furnace and to/improvement of the smelting
targets. An analysis of the movement pattern of the inner-
furnace gas flow would help achieve such a goal. Some of
China's steel works, since adopting the technique of sliding
gate casting of aluminium-killed high-carbon and medium-
carbon steel, have frequently suffered from slag-bonding at
the sliding gate. And it is by means of the tracer atom
(calcium-45) that it is found that the main cause is the too-
high calcium content in the liquid steel; hence strict
measures are taken to limit the calcium content in silicon
iron. As a result, the said bottleneck problem is basically
solved so that the quantity and quality situation has been
substantially improved and the cost has been reduced.
Tracer Sand and Tracer Water
By proper means, tracer atoms can be infiltrated into
the sand and water, thus forming the tracer sand and tracer
water. These two tracer agents play an extremely important
role in water conservancy, hydrological engineering and civil
engineering.
