What did we do?

PERMANENT SUPPLY OF INDUSTRY EXPERTISE, PROBLEM SOLVING COMPETENCE AND PROACTIVITY

In detail we provided expertise through more than 80 specialists for a duration of seven years for areas such as the site’s port, coke plant, sinter plant, blast furnace including host blast system, granulation, gas cleaning and dedusting and steel mill (melt shop, caster and slab yard) along with the plant’s piping and conveying.

What did we supply?

• Refractory design and erection supervision,
• Design of erection sequences,
• Degrees of preassembly,
• Erection studies,
• QA/QU,
• Progress control
• Site management
• Warehousing and logistics design along with supervision of partially more than 110 transports per ten hour shift
• OPIs of more than 350000 tons
• Commercial and process control of slab yard piling and crane utilization

Extract of problems and our solutions

At that time, experienced welders were a scarce resource. To solve this problem, we supplied 40 highly skilled welders for 24 months and developed an on site training center educating welder on the basis of ASME that finally welded the blast furnace steel jacket and the hot stove, for example.

Further, our colleagues developed the entire blast furnace erection concept by means of the degree of preassembly, weights, dimensions, load cases and erection methodologies. Without any progress on site, we had to develop a transportation and lifting concept incorporating crane positions for the entire project duration – especially important since the vulnerable ground conditions had to be supported by intensive piling activities that were defined on the basis of the resulting pressures as a result of lifting and transportation.
