Wire & Cable ASIA – July/August 2013
The Taiwanese Formosa Plastics Group has contracted
German company Friedrich Kocks to supply a 3-roll
reducing and sizing block in heavy duty design (RSB) for
its Vietnam based subsidiary Formosa Ha Tinh Steel
Corporation.
Formosa Plastics Group, with some 100 affiliate
companies and about 100,000 employees worldwide, is
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 410km south of Hanoi City and 1,300km
north of Ho-Chi-Minh City. With a total production capacity
of 15 million tons per year year this will be the largest
integrated steel mill in the ASEAN (Association of
Southeast Asian Nations).
The 370mm heavy duty reducing and sizing block will be
operated as finishing block in the new 600,000t/a rolling
mill for special bar qualities downstream the 16-stand
roughing and intermediate mill.
The RSB is equipped with four stand positions and is
designed for controlled rolling at low temperatures down to
750°C. The 3-roll block rolls round bar in coils within the
range from 20mm Ø to 55mm Ø.
The RSB allows rolling out of only one pass series with just
five 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 required 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 and 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 its new wire
rod and bar mill, Formosa Ha Tinh Steel will have at hand
the most advanced tool for a trouble-free, economic
production of top quality SBQ bar.
