THE ECHO - Ferrostaal

of the water treatment system, installation of various electrical
buildings and pipework and the assembly of numerous components.
The largest crane, with a hoisting capacity of 600 tons, was
brought in from Trinidad. After erecting the last heavy components
to a height of over 100 m (including the blast furnace
gas valves, valve platform and the highest component of the main
conveyer belt, which weighed in at 100 tons), the crane was
dismantled and shipped to the next construction site. After the
most important equipment and piping were installed by
THE ECHO 1/2006 31
April/Mai 2006, electrification of the facility was successfully
completed with the special involvement of the ALSTOM.
The test series of the individual components and areas of the
facility are currently being conducted as sequence tests. Cold
commissioning and handover of the entire furnace is scheduled
for July 2006.
