Our scope of work

The SGS team was responsible for upgrading the stainless steel converter AOD#1 including the dedusting system. The upgrade consisted of replacing the trunion ring, including the tipping station, and all modernisation work and it was completed during a shutdown of several weeks at the end of February 2023.


New installation of stainless steel converter AOD#2 incl. dedusting system.

A new plant was installed directly next to the stainless steel converter AOD#1. In addition, a new filter system for fume extraction was installed in November 2022.

  The challenge in this project was the limited space available, as the new line AOD#2 was installed in an existing plant.

Challenges are there to be met.

In addition to the limited space available, there was a second component, time. The mechanical assembly of the plant must be completed within a six-week shutdown starting in June 2023.


The SGS team will install around 5,000 tonnes of plant components and steelwork as part of the upgrade and new construction.

Milestone reached: 14 tons assembled with millimeter precision by the #SGSteam in Belgium

A team of around 15 employees reached a milestone in the project in June 2023.

After four days of pre-assembly, the #SGSteam assembled the 14-ton section of the boiler piping in just 5 hours at the future location.


Some TIG weld seams in pre-assembly required around 12 hours of manpower.

After measuring and transport preparation by our team, the piece of pipe with a wall thickness of 20mm and 100% stress-free construction was assembled at a height of 60 meters using a 550 ton crane.
