Largest integrated steel mill in ASEAN with 3-roll Reducing & Sizing Block
The Taiwanese FORMOSA
PLASTICS GROUP has contracted German company FRIEDRICH KOCKS GmbH & Co KG to
supply a 3-roll Reducing & Sizing Block in heavy duty design (RSB) for their
Vietnam based subsidiary FORMOSA HA TINH STEEL CORPORATION.
FORMOSA PLASTICS GROUP with
some 100 affiliate companies and about 100,000 employees worldwide is by now the
largest private enterprise in Taiwan.
The RSB will be installed
in the combined wire rod and bar mill of the new integrated steel mill project
in the Vung-Ang Economic Zone of the Ha Tinh Province. This is located 410 km
south of Hanoi City and 1300 km north of Ho-Chi-Minh City. With a total
production capacity of 15 million tons / year this will be the largest
integrated steel mill in the ASEAN (Association of Southeast Asian Nations).
The 370 mm heavy duty
Reducing & Sizing Block will be operated as finishing block in the new
600,000 t/a rolling mill for special bar qualities downstream the 16-stand
roughing and intermediate mill. The RSB is equipped with four stand positions
and designed for controlled rolling at low temperatures down to 750°C. The
3-roll block rolls round bar in coils within the range from 20.0 mm ? to 55.0 mm
?.
The RSB allows rolling out
of only one pass series with just 5 feeders from the roughing and intermediate
mill. Due to the “free-size” rolling capability any desired finished dimension
within the complete dimensional range can be produced in any desired sequence
with a minimum number of roll sets and just a few stand changes. The optimum
adjustment values for motor speed, rolls and guides as well as gear steps are
calculated by the bar mill configuration system BAMICON in relation to the final
product.
Besides the Reducing &
Sizing Block with the automatic quick stand changing system the scope of supply
comprises the bar mill configuration program BAMICON and the remotely controlled
adjustment of pass and guides of the 3-roll stands in the mill line as well as
the roll shop with quick roll change and CAPAS, the computer aided system for
accurate adjustment of rolls and guides in the stands. The supervision of
erection, commissioning and the training of customer personnel complete the
contract package.
Implementing the 3-roll
Heavy Duty RSB into their new wire rod and bar mill FORMOSA HA TINH STEEL
CORPORATION will have at hand the most advanced tool for a trouble-free,
economic production of top quality SBQ-bar.
