The growth plan will
have new facilities at all the stages of production, i.e., coke making,
sinter making, blast furnace and steel making facilities. The 1.0 mtpa
expansion programme included up-gradation of existing ‘G’ blast furnace
hot metal capacity from 1.0 mtpa to 1.80 mtpa and a sinter plant. Thus
the sinter plant No. 3 (SP#3) along with a bedding and blending facility
RMBB (N) has been commissioned. The plant and machineries have been
supplied by M/s Lurgi, Germany. M/s L&T is their Indian counterpart and
a partner in erection of the plant. It has a 6.0 mtpa raw materials
bedding facility (keeping in view the requirements of SP#4) and a 2.0
mtpa state-of-the-art sinter making facility possessing all most all the
recently developed features in the area of sinter making technology. The
plant has a provision of second sinter machine and the RMBB(N) can be
made to 6.0 mtpa.
The First Plant
The first plant (SP#1)
is a 1.20 mtpa capacity plant. It was designed and supplied by M/s Lurgi,
West Germany. This was commissioned in March 1959. It has two machines
each having 75 m2 sintering area. The details of sinter plant#1 are
presented in Table 1. The plant was designed to produce acid sinters
which were converted to basic sinter making in the late years of
sixties. Today the plant is performing comparable to any modern plant at
1.60 mtpa.
The Second Plant
As the production and
quality of sinter from first sinter plant improved the percentage of
sinter in blast furnace burden increased. During eighties it was at a
level of 40+ percent. This resulted in lower coke rates, lower hot metal
silicon and higher blast furnace productivity. Encouraged with these
highly desirable benefits in line with global observation, it was felt
beneficial to further increase the proportion of sinter in blast furnace
feed. Accordingly a 1.37 mtpa state-of-the-art sinter plant with raw
materials bedding and blending facility, the bedding blending & sinter
plant # 2 (BB&SP#2 in short, SP#2 hereafter) was commissioned under the
second phase of the modernisation programme in 1989. The plant comprises
two units: (a) bedding and blending plant and (b) sinter plant # 2. The
equipments have been supplied by Lurgi, Germany. The bedding and
blending plant has a 3.0 mtpa capacit
