The CISDI-built blast furnace 1 for Ningbo Steel has started up smoothly. CISDI is playing an important part in building a green and intelligent Ningbo Steel, and undertook the furnace project to an EPC basis.

The relocation of blast furnace 1 creates an environmental and technological upgrade and is an important step in Ningbo Steel’s aim to improve production capacity and quality.

The furnace has been moved to a reserved site at the existing ironmaking plant. Its volume is unchanged at 2,500 cubic metres and it will continue to tap 2.13 million tonnes of hot metal a year.

CISDI’s patented top serial hopper, top gas dedusting and bleeding, top equalised gas recovery, top-combustion stove and intelligent slag removal technologies have been successfully applied to the blast furnace.

They contribute to energy conservation and environmental protection at the ironmaking plant.

The relocation posed great challenges for CISDI. There was limited space for construction work to be carried out, civil work was problematic, foundations needed treatment and it was important the production was not affected.

But CISDI’s team tackled the obstacles and fulfilled the project on schedule.
