Shandong Steel Rizhao Meltshop’s BOF3 hot commissioned

Blast furnace three at Shandong Steel‘s Rizhao Meltshop has produced liquid steel for the first time.

The furnace was successfully hot commissioned two months ahead of schedule and has produced its first heat of qualified liquid steel to designated standards.

The meltshop has been built in two stages, with Phase One started up at the end of 2018. Four KR hot metal desulphurisation units have been installed, along with four 210-tonne BOFs, two dual-duty-position LFs and utilities.

Successful hot-commissioning of Phase Two has laid a solid foundation for a full-plant start-up of Rizhao’s prime products base.

CISDI’s construction schedule and build quality have been praised by Shandong Steel.

Fact file

CISDI has now undertaken two EPC-based projects for Shandong Steel Rizhao - its meltshop main systems and two 300,000-cubic-metre blast furnace gas holders.

To assist at Rizhao, a prime example of China’s acceleration in steel industry restructuring, CISDI calculated the optimised steel manufacturing process flow and total technology solutions. Comprehensive studies were carried out on the process route, technical specification, equipment type and sizing and general layout.

The optimised general layout delved into the mass flow, energy flow and information flow, and their tracks and regularities. This created more channels for implementing intelligent operation and control, resulting in the best economic returns and a great reduction of OPEX.
