The site for Use Case 1: Plant Lubrication was the LKAB
pelletizing plant KK4 in Kiruna, Sweden.
At the pelletizing plant a mixture of ground up iron ore and
additives is rolled into small balls which are then heated to
become pellets.
Use Case 1 consisted of
replacing the traditional control
system of the grate lubrication
system with an IMC-AESOP
architecture.
Several SOA based components
were developed to achieve a
smoother integration.

Illustrated above is one of the two lubrication circuits
for the Grate. Each lubrication circuit consists of one
air-pressure-controlled pump supplying the lubrication
fluid to distributor valves, alternatingly through Line A
and Line B.
The Mediator
provides a runtime
system for
monitoring and
control of process
facilities by
integrating both
legacy as well as
SOA-based
technologies.
The Distributed Service
Bus provides an
additional integration of
heterogeneous systems
supporting various
communication media,
protocols, and data
models. The integration
is enabled through loose
coupling-based protocol
connectors.
The core components of the Grate
lubrication are the magnetic valves
which control the lubrication pump and
the change over valve.
The distribution valves are operated
through the alternating pressure in the
distribution lines Line A and Line B. As
the pressure is rising in one of the
distribution lines a set amount of
lubrication fluid is distributed to a
number of lubrication points, in this
case on one of the Grate Support
Shafts.
The position of the distribution valve is
detected by an AS-i Pressure Switch,
which is supervised by the control
system.

Mulle devices were used as I/O nodes connecting
lubrication pressure switches, air pressure switches,
pump valves, change over valves, and indication lights.
