Mega-blast furnaces at Baosteel’s Zhanjiang plant have been officially recognised as reaching world-leading levels.

The evaluation comes from the Chinese Society for Metals, who carried out an evaluation forum at the plant and examined the scientific and technological benefits achieved by the application of CISDI’s mega-blast furnace no-bell top key technology and equipment.

After investigating Zhanjiang’s blast furnace 1 and 2 central control buildings, casthouses and command centres and examining all the documentation, the reviewers came to a consensus that the applications had reached world-leading levels.

All key technologies and equipment were solely developed by CISDI and have been granted 55 patents, including 21 patents of invention and four overseas patents.

In addition to Zhanjiang’s two blast furnaces, CISDI’s no-bell key technology and equipment have been successfully incorporated into over 10 mega-blast furnaces, including those at Baosteel Shanghai, POSCO and Formosa Ha Tinh. Strong social and economic benefits have been praised by CISDI’s clients.

Key innovations of CISDI’s no-bell blast furnace top:

<!--[if !supportLists]-->●       <!--[endif]-->The BCQ (Baosteel, CISDI and Qinye) top distributor at the core of the patented technologies and equipment has a simple structure, works reliably, gives an extended service life and withstands high pressure and high temperature. This contributes to higher-precision production

<!--[if !supportLists]-->●       <!--[endif]-->Self-reliant top equipment and facility enables the blast furnace to run smoothly, operate more efficiently and consume less energy, ensuring an overall enhancement of the blast furnace’s production indicators and stable operation
