CISDI has received high praise from Rizhao Steel after delivering a high-performance BOF steelmaking plant.

Rizhao Steel is China’s large private steel group. In addition to its skills in sintering, ironmaking, steelmaking, pickling, plating and tubular rolling, it is an enterprising producer of optimum-quality strip which accounts for over 70 per cent of China’s rolled products output.

Rizhao Steel projects are critical to the transformation of China’s steel production and CISDI has been involved in a number of highly advanced technological upgrades for the company.

CISDI was an active player in the construction of the world’s most advanced ESP lines at Rizhao, which are able to produce ultra-thin sheets to a specification of 0.8-6mm x 900-1,600mm, filling the gap in Chinese endless strip rolling and production.

It was also involved in the modernisation of the main BOF steelmaking plant and two 300,000m³ blast furnace gas holders, both on an EPC basis, winning Rizhao’s praise for its expertise and its painstaking attention at every stage of the process - from general layout to process route, technical proposal and equipment selection.

CISDI had carried out an in-depth analysis of the BOF plant’s mass flow, energy flow, information flow and movement track prior to creating the most optimal production process.

The general layout and transport system was optimised to achieve the maximum benefit. High-tech design tools and innovation solutions were used in the design process  and a full intelligent operation and management system was implemented. As a result, production and management costs have been reduced.

The BOF steelmaking plant was successfully hot commissioned despite multiple challenges posed by the weather and the financial markets. It was ramped up within a month of hot commissioning.
