CISDI wins second blast furnace revamp at Maanshan Steel

CISDI has won the contract to modernise Baowu Maanshan Steel’s blast furnace B.

The furnace will shut down in September for a 3.5-month conversion to safer, greener and smarter operations.

BF ‘B’ had its first blow-in in 2007.

CISDI carried out the feasibility study report for the rebuild, focussing on creating favourable conditions for applying fast revamp expertise and the offline assembly of a new dry dust collection system.

A highlight of the general layout solution is the relocation of the casthouse’s elevated passage and optimising existing water pump houses by creating a centralised arrangement.

Advanced tech and equipment has been designed for achieving transformative targets:

✔         Optimised blast furnace profile

✔         Upgrading the existing casthouse to a flat casthouse

✔         Installing a smart slag collection unit which will operate without manpower

✔         Installing ultra-low emissions systems.

Blast furnace A at Maanshan Steel, supplied by CISDI, was blown in at the end of 2021.

It has achieved an average daily output of 10,488 tonnes of pig iron, featuring a productivity of 2.622t/(m³•d).

Additional advanced indicators are being achieved during operation - a fuel ratio of 500kg/t, composed of 340kg/t of coke and 160kg-plus/t of coal, and an enrichment ratio of 5 per cent.

CISDI’s leading technology and fulfilment skills gained praise from Maanshan Steel, who had no hesitation in entrusting CISDI with the contract for its furnace B.
