revised to consider a new distribution of responsibilities.
In addition to the delivery of new furnaces,
new technologies developed by Drever
International have been applied to existing
lines resulting in improved performances. For
example, our advanced mathematical model
has been successfully commissioned on all
new lines, but has also been implemented
on older lines, resulting in a high level
of customer satisfaction. Drever’s direct
hydrogen injection system is now supplied on
all new ultra-fast gas jet cooling systems, but
has also been applied to existing rapid cooling
installations resulting in higher cooling rates,
and a corresponding higher productivity and
signi# cantly lower electrical consumption.

ISSUE 7 MAY 2012
Grand Ceremony for the Start-Up of 600,000 t/y Annealing and Pickling
Line Held at Zhenshi Group Easter Special Steel Co., Ltd.
The combined Hot and Cold Stainless Steel Annealing and Pickling Line has successfully started production in
September 2011. The line has a designed annual capacity of 600,000 tons and is more dedicated to special steel
products such as Duplex, heat-resistant and super stainless steel grades (Refer to DOL N°4). The construction
involves renowned suppliers from both international and domestic like DMS, Drever, DISA, Guild, PPH and
Aritime.
After the ceremony which was held in Jiaxing on November 8th, we had
an exclusive interview with Mr. Gu Pei Song, the Technical Leader of the
project and here are the discussions.
What is your feeling after having reached the goal
to start the production?
To manage such a big project where most of the equipments are coming
from the local market is not an easy job. It is really a huge work to coordinate
all parties and have all the equipments erected and commissioned on time.
It was tough but now we can see the result of all parties’ efforts. I would like
to express my gratitude to all the suppliers involved in this project.
What about the product quality?
As a privately owned stainless producer, the start up of this line has a big
influence in China. Immediately after the coming out of the first coil, I got
the congratulations from many key players on the Chinese steel market.
At the beginning of the production, we reached the quality level of the
top Chinese producers and we even increased our prices on the market
by 300CNY/ton. This is really a miracle to reach such a quality level after
only a few weeks of production. There are still some tunings to be done
but we are gradually stepping up to higher grades and we are already
able to process 2205 material which is produced only by very few Chinese
producers.
How do you explain this success?
From the beginning of the project, our management realized the
importance of the technology and the use of top quality talents. We also
invested a lot in research and development to be able to produce these
special grades. After this success, I still believe that Drever was the best
choice and is the best furnace supplier. Even with the young operators
team, we reached the quality and the productivity of the best steel
producers in China. It is really out of my expectation that everything
started so smoothly.
What do you think about the ceramic " ber furnace
insulation?
Fiber insulation proves it is indeed an ideal solution for APL furnace. I had
experience before with many brick wall furnaces and operating with fiber
lining is quite different. It has the benefits of fast responding and better
flexibility. Besides the erection time was greatly reduced.

Largest Privately Owned Steel Producer Goes for Value Added Cold Rolled Products.
Zhangjiagang Yangzi River Cold Rolling Co., Ltd., a newly founded subsidiary of Jiangsu Shagang Group has o$ cially launched 1420
mm cold rolling project on December 8th,2011, symbolizing the implementation of the group’s developing strategy, to optimize products
structure, further extend business area and emphasize on value added cold rolled strip production.
Inauguration of a pilot plant for a Roll Regenerative Furnace :
an achievement of a successfull collaboration between Drever and IVK.
Headquartered in Yangtze River delta’s Zhangjiagang City Shagang Group
is the largest private steel enterprise in China. Once a small steel work
founded in 1975 Shagang is now among top 5 gigantic Chinese steel
complexes with annual output of 31 million tons. Their products include
heavy plate, hot rolled coil, bar, high speed wire & rod, stainless hot and
cold rolled strips. The techno-economic level of Shagang Group remains
at the highest in the industry. In 2006 Drever International built a large
production stainless HAPL in its joint-venture ZPSS.
The new 2.6 million t/y cold rolling plant will cover mostly valued added
products on the market such as tin-plate, cold rolled coil, galvanized and
galvalumed strip as well as NGO silicon steel sheet. The total investment
is about 4.3 billion RMB and the project construction expects to complete
in 2 years. On October 29th, a plain signing ceremony was held between
Shagang Group and members of SMS Siemag Group for the three major
processing lines of the cold rolling mill.
Thermal process engineering for electrical steel strip.
ArcelorMittal orders Drever furnace for annealing and coating line.
With a new annealing and coating line, ArcelorMittal St-Chély d`Apcher, France, is drastically increasing its production capacity of high-
grade non-grain-oriented electrical steel strip (NGO). The order to supply the horizontal furnace for the new line was awarded to Drever
International on 13 May 2011. The line is scheduled to be commissioned already in December 2012.
Non-Grain-Oriented Electrical Steel Strip
Due to its electrical and magnetic properties, non-grain-oriented
electrical steel strip (also referred to as silicon steel strip) is predominantly
used in electrical engineering for the manufacture of cores for electrical
machines. Since the orientation of the ferrite grains (texture) is randomly
distributed, the material has largely isotropic mechanical and magnetic
properties and is used chiefly in rotary machines with alternating field
orientation. The material produced on the new line can also be used in
hybrid or full electrical vehicles.
Annealing and Coating Line
In the annealing and
coating line, the internal
microstructure of the 0.18 to
1.5 mm thick strip is adjusted
during the annealing process.
The material, of a width
between 800 and 1,350 mm,
is then provided with an
insulating layer depending on
requirements. The new line
will be the third annealing
and coating line in the
ArcelorMittal works at St-
Chély d`Apcher.
> Fig. 2: The strip is cooled down in a controlled manner in the cooling tube section> Fig. 1: Horizontal furnace in an annealing and coating line for NGO electrical sheet
Horizontal Annealing Furnace
In the horizontal annealing furnace the strip is heated > 1000°C, with the
thermal energy being introduced by means of inductors and electrical
heating elements. The furnace atmosphere comprises a nitrogen-
hydrogen mix.. This is a new ACL furnace that can be operated with a very
high hydrogen content This reducing atmosphere enables a particularly
oxide-free and clean strip surface to be achieved, which is important for a
high-quality material grade.
Furthermore, a careful and slow cooling of the material is important
for the microstructure. For this reason, the strip is first cooled down at
very accurate cooling rate in the slow-cooling section and then in the
quick-cooling section. A particular feature is the heat-recovery system in
the cooling section, which makes it possible to utilize the heat at other
locations in the works. The remaining heat, though, is also intended for
other purposes, for example for heating the local swimming pool by
means of distance heating.
> Earlier this year, representatives of Regional Authorities and SMS Siemag A.G. took part in the inauguration ceremony of a pilot plant for a Roll Regenerative Furnace
in the von Karman Institute for Fluid Dynamics. Drever International S.A. collaborates with this Research Center for several other research projects, under the leadership
