At 9:25 AM on September 25, 2015, when Baosteel celebrated its 30^th anniversary of blast furnace startup, the No.1 blast furnace at Baosteel Zhanjiang Steel Base was held the blow-in ceremony. The kindling fetched from the No.4 BF at Baosteel Shanghai ironmaking plant lit up the torch at 10:12 AM and the hearth of No.1 BF was immediately ignited by that torch, hot air blown in.

 

The No.1 BF at Zhanjiang Steel Base was designed by CISDI with 5,050m³ volume, expecting for serving one campaign of 22 years and producing hot metal of 4.115Mt/a. It was involved in partial procurement by CISDI, maximizing the self-relied design and integration of ironmaking process, equipment and technology.

Aiming for building it a world’s representative mega blast furnace, high-quality and -efficiency, long campaign, environmental-protection, energy and cost saving, CISDI brained out of the over-30-year experience and innovatively arranged the two sets of stockhouse, water pumps and central control rooms for both No.1 and 2 BFs in their respective buildings in centralized way, minimizing the space coverage among the same volume level of BFs. CISDI made multiple optimizations of general layout to match the afore-said centralized arrangements. CISDI was encouraged to use the home-made BCQ top, blower, TRT unit and cast-iron cooling staves for the first time for the 5,000m³-level BF, and deliver the top-combustion stoves and gas cleaning system on EP basis for the first time for the 5,000m³-level BF. CISDI paid much attention to the energy efficiency and environmental protection aspects and hereby carried out the most-demanding design and equipment in terms of relevant criteria.

 

The Zhanjiang No.1 BF was started piling in May 2013 and all-round construction in that September; during the two years of frontline struggles, CISDI engineers specialized in ironmaking, thermal power, power supply & distribution, civil, water supply & drainage had stationed long at site. They are heroes overcoming difficulties in climate and geology, tight schedule, hard construction and long-distance equipment delivery. Efforts repay! The high-quality technology and services and the spirit of CISDI light up the No.1 BF and win the praise from the client and partners.
