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.
