| Abstract |
| In integrated steel plants of India, steel ignots are heated to a maximum
temperature of 1300°C in soaking pits for rolling as blooms or
slabs. The conventional sand seal between the pit cover and pit wall
is not very effective and results in poor life of cover structure and its
castings apart from large energy loss. With an objective of effective
sealing and to eliminate the associated problems, RDCIS in association
with Bokaro Steel Plant has developed the design of ceramic
fibre sealing system and installed the same in one of the Bokaro
soaking pits in August 1984. The paper outlines as to how efficiently
ceramic fibre seal could be used as a measure for eliminating problems
associated with conventional sand seal. The studies have revealed
that there is a minimum saving of energy to the tune of 9-10%
and 0.2 to 0.5% improvement in the slab yield with the new ceramic
fibre seal apart from generating an effective seal. |
