DAYE Special Steel Co Ltd, part of
the Chinese CITIC Pacific Steel
Group, will install a medium section
mill in Huangshi, southeast of Hubei
province, approximately 150km
southwest of Wuhan.
The order for the finishing mill, a
3-roll reducing and sizing block
(RSB), was placed with the German
company Friedrich Kocks.
The decision in favour of this
machinery was highly influenced by
the performance and the trouble-free
operation of the RSB in Daye’s
existing speciality bar mill.
Daye is one of the largest special
steel producers in the country. The
products are widely recognised and
accepted by both domestic and
international companies and are used
in nearly all fields of application.
The heavy duty reducing and sizing
block is equipped with four stand
positions and is designed for
controlled rolling at low
temperatures. With a nominal roll
diameter of 500mm this is so far the
biggest 3-roll RSB.
It will be operated as finishing block
in the 900,000t/a medium section mill
downstream the 16-stand 2-high
roughing and intermediate mill.
The RSB rolls round bar in special
bar qualities within the range of
50mmØ to 130mmØ in straight
lengths onto the cooling bed.
The reducing and sizing block allows
rolling out of only one pass series
from the roughing and intermediate
mill and significantly reduces the
number of required feeders down to
only five.
The RSB can produce any required
finished dimension of the complete
dimensional range in any desired
sequence with a minimum number of
roll sets and just a few stand
changes.
The scope of supply comprises the
3-roll reducing and sizing block with
automatic quick stand changing
system, the roll shop with quick roll
change, the mill configuration
program Bamicon, the inline remotely
controlled pass and guide adjustment
and Capas, the computer-aided
system for accurate adjustment of
rolls and guides of the 3-roll stands in
the roll shop.
Supervision of erection, comm-
issioning and training of customer
personnel are also Kocks’ resp-
onsibility.
The start-up of the new medium
section mill incorporating the 3-roll
reducing and sizing block will enable
Daye to meet the set target of
becoming the most competitive
future-orientated special steel
company in its market.
