How to gain maximum revenue at minimum cost, while simultaneously managing
risks, optimizing quality and keeping one’s customers satisfied in ways that are
environmentally sustainable? These are the questions that pulp and paper makers face
every day at the mill.Successful production at today’s mills requires the constant,
intensive use of information. Production professionals such as
operators, production managers, maintenance engineers and
development engineers work hard to attain their performance
goals. The best results are achieved when they all work together.
Modern automation makes all of this possible. Metso has built its
automation know-how on a thorough understanding of customer
processes and machinery. Metso has also been a pioneer
in developing the industry’s most comprehensive automation
offering, based on single network thinking. Metso believes that

machine controls, quality controls, drive controls, condition monitoring,
web-break analysis and inspection, and process optimization
- should be implemented in the same environment. This also
applies to the industry’s leading specialty analyzers, measurement
instruments and valves. As a result, users can collect and combine
information from different sources, using the same information
tools and engineering applications. This leads to easy decisionmaking,
since the automation system is there to serve users and
provide tangible results.
This article will present some recent cases, showing how
customers have achieved results through Metso’s technology and
automation know-how.

» A Modular Simulation System for Semiconductor Manufacturing Scheduling
|
|
Li LI  Fei QIAO
A modular simulation system (MSS) for the scheduling of semiconductor wafer fabrication facilities (fabs) is discussed. Firstly, the general
structure model (GSM) for modeling a semiconductor wafer fab, composed of a configurable definition layer, a physical layer, a process information
layer and a scheduling layer, is proposed. Secondly, a data-based dynamic modeling method is given. Thirdly, the architecture of MSS, composed of
data layer, module layer and simulation layer, is presented. Finally, a case study is used to demonstrate the effectiveness of MSS.

Słowa kluczowe: planowanie, półprzewodniki, symulacja.
Introduction
Discrete event simulation technology, imitating a real
production environment by modeling, has been applied to
semiconductor manufacturing scheduling since 1980s. For
example, Wein [1] built three kinds of HP24 simulation
models to compare various release control strategies and
scheduling rules and proved that the release control
strategies may be more important to the performance of a
semiconductor wafer fabrication facility (fab). Baudouin et
al.[2] presented an information system architecture and a
decision support tool to allow admissible scheduling
solutions in a semiconductor device manufacturing fab.
Thompson [3] developed a simulation-based finite capacity
planning and scheduling software to allow human planners
to make better decisions. This tool improved cycle time,
throughput, and equipment utilization significantly without
adding additional equipment and personnel.
Presently, discrete event [...]

|
Zhou HONGGEN Jing XUWEN Pan BAOJUN Zhang XIAOJUN
In order to satisfy new requirements for process planning and resources sharing in E-manufacturing, the structure and key technologies of
the dynamic process planning and supporting system were discussed. The results show that the methods for building and storing manufacture
model based on ontology could make the model have semantic nature. Theory studied in this paper laid a foundation for the process planning
system, which not only to grasp the dynamic resource information, but also to realize the process resources and knowledge sharing, as well as to
realize the process route optimization selection.
Streszczenie. Zaprezentowano stadium teoretyczne tworzące podłoże dla system planowania procesu które nie tylko ma pod kontrolą dynamiczne
zasoby informacji, ale także realizuje zasoby I przeprowadza optymalizację. (System planowania i wspomagania procesu przy Emanufacturing)
Keywords: e-manufacturing; process planning and supporting system; manufacturing ontology; semantic retrieval.
Słowa kluczowe: E-manufacturing, optymalizacja, planowanie..
Introduction
E-manufacturing is an online network manufacturing
which is not only driven by orders or the market forecasting
but also based on collaborative manufacturing business. It
is also an extension and expansion of network
manufacturing system. E-manufacturing has many
advantages, such as on-line, synergy, dynamic, agility and
accuracy etc [2]. Process planning support system is the link
that connects the design with production and also is the
information centre of whole manufacturing system. The
pattern of e-manufacturing requires not only the process
planning to support transaction processing in different
enterprises and within the enterprise but also optimization
of multi-process routes based on the bottom-up and
process data feedback, besides the mutual coordination
and compromise in process planning of different parts’ are
also required. Therefore, dynamic and instantly share[...]

Egbert BAAKE Bernard NACKE
A wide range of industrial metallurgical heating and melting processes are carried out using electromagnetic sources. The application of
electromagnetic processes offers many advantages from technological, ecological and economical point of view. Although the technology level of
the electro heating and melting installations and processes used in the industry today is very high, there are still potentials for improvement and
optimization. In this paper recent applications and future development trends for efficient heating by electromagnetic sources in metallurgical
processes are described along selected examples in the field of heating for forging, rolling, hardening, joining, and pressing..
Streszczenie.. Większość przemysłowych procesów metalurgicznych dotyczących nagrzewania i topienia jest przeprowadzana z wykorzystaniem
źródeł elektromagnetycznych. Zastosowanie procesów elektromagnetycznych daje możliwość uzyskania wielu korzyści z technologicznego,
ekologicznego oraz ekonomicznego punktu widzenia. Pomimo, że poziom technologiczny urządzeń stosowanych obecnie w nagrzewaniu

» Effect of the extruded blank cooling method on the mechanical properties of AZ31 alloy wires
|
|
TERESA BAJOR
AZ31 magnesium alloy wires after the isothermal extrusion process carried out by the KOBO method in two variants, namely with
additional cooling after extrusion (Variant II) and with static cooling (Variant I), were subjected to the cold multi-stage drawing process,
while applying interstage heat treatment. The wires were tested for mechanical properties in each of the states of strain under
analysis. The main purpose of the work was to determine the effect of the method of cooling after extrusion on the drawing process.
Observations of the development of material microstructure during the drawing process were also made using an optical microscope.
Druty ze stopu magnezu AZ31 po procesie izotermicznego wyciskania metodą KOBO w dwóch różnych wariantach, a mianowicie
z dodatkowym chłodzeniem po procesie wyciskania (wariant II) i chłodzeniem statycznym (wariant I), poddano procesowi ciągnienia
wielostopniowego na zimno, stosując międzyoperacyjną obróbkę cieplną. Przeprowadzono badania własności mechanicznych
drutów w każdym z analizowanych stanów odkształcenia. Głównym celem pracy było określenie wpływu sposobu chłodzenia po
wyciskaniu na przebieg procesu ciągnienia. Przeprowadzono również obserwacje rozwoju mikrostruktury materiału podczas procesu
ciągnienia za pomocą mikroskopu świetlnego.
Key words: isothermal extrusion, KOBO, drawing process, magnesium alloys, intermediate annealing
Słowa kluczowe: izotermiczne wyciskanie, KOBO, proces ciągnienia, stopy magnezu, wyżarzanie międzyoperacyjne.Introduction. Owing to their physical properties,
magnesium alloys have become an important product
that has found application in many sectors of the
economy, including the automotive, electronics, and
many other industries [1÷4]. It should also be noted
that magnesium alloys belong to a group of materials
