CISDI’s latest success at Rizhao

CISDI’s latest success at Rizhao

Shandong Steel’s Rizhao steelmaking plant has announced the successful hot commissioning of its hot metal KR-process desulphurisation system 4.

All major production facilities at the plant are now operational.

CISDI is the plant’s main contractor. Its unique purging de-slagging development has been applied to the four KR de-S systems. Key features are a very simple structure, easy maintenance, facilitated slag skimming, more efficient desulphurising and a shorter treatment cycle. 

The last two de-S systems were constructed while four BOF were in operation.

CISDI faced numerous difficulties. The project team had to work to a challenging time schedule to avoid any interference with production at the plant, and assembly of reusable devices had to be done in situ.

But thanks to the team’s well-organised management and experiences learned during construction of the first two KR de-S systems, difficulties were overcome and project targets were achieved.
