Upgrading Desheng’s blast furnace 1 boosts green standards

Baosteel Desheng Stainless Steel Co has upgraded its Blast Furnace 1 as part of the plant’s bid to improve its environmental indicators.

CISDI was the rebuild designer and supplier and the blast furnace has now been blown in.

The steelworks, based in Fuzhou City in China’s Fujian Province, is upgrading its main equipment to ultra-low emissions standards.

CISDI is tasked with rebulding blast furnace 1’s stockhouse, top, proper, tuyere platform and casthouse, slag granulating and raw gas cleaning systems, its fuel gas, water treatment and HVAC facilities, and electric and automation system.

A host of CISDI new tech and units have been applied to enhance performance and green credentials:

✔         Innovative cooling staves installed at the furnace proper and the addition of a heat load measurement system will ensure safer and longer production

✔         Rebuilding the old casthouse to flat, with taphole areas at the casthouse enclosed, creates a cleaner working environment

✔         Addition of a chimney at the slag granulating system improves the environment surrounding the slag runner

✔         A gas relief and recovery system added at the furnace top, and setting more dust collection positions, will result in greener indicators

✔         More dust collection positions set at the stockhouse will maximise dust cleaning

“We worked against a tight schedule, long-lead time for supplies and manufacture and delivery issues caused by the pandemic. Our team ensured major resources were in place and reused existing equipment to get around the fact that new items were unavailable”, said a CISDI spokesperson.

“We optimised all procurement plans and dispatched our manufacturing supervisors to workshops for schedule control.”

Desheng has praised CISDI’s relentless work over a four-month period to ensure smooth coordination between client and construction company.
