During the construction of Hansteel New Area Project, CERI adhered to the advanced construction philosophy of a new generation of integrated iron and steel enterprise featuring "high-end, green and intelligence". It adopted advanced metallurgical process integration theory and method, applied dynamic precision design and process interface technology, and fully utilized existing equipment and sites, successfully building an ultra “compact" long-process steel manufacturing base. 

Project highlights 

In the scheme demonstration stage of the Project, CERI made more than 100 adjustments to the general layout plan with the objectives of being compact, continuous, optimal, and efficient. Through repeated study and optimization, CERI comprehensively integrated the process layout and fully utilized the existing equipment, greatly reducing construction costs. Hansteel New Area Project realized an equipment reuse rate of about 65%, setting one of the highest records in the history of metallurgical relocation projects. In the construction drawing design stage, CERI actively implemented the work requirements of the State Council on energy conservation and carbon reduction. It adopted a "straight line" layout for main production facilities and made clear functional zoning and compact logistics arrangements according to topography, transportation, energy, and other conditions, realizing a balanced, orderly, and efficient flow of material, energy, personnel, and information across the plant. The land occupation per ton of steel in the plant is only 0.42 m², the lowest figure for steel mill construction in recent years, reflecting an industry-leading standard. 

At the same time, layout optimization is more conducive to realizing the ultimate efficiency of steel production. The interface distance between iron and steel in the Project is only 260m, which contributes to the control of hot metal temperature drop within 60~70°C and the turnover rate of hot metal ladles reaching 6 times/day. The hot delivery and hot charging conditions of steel rolling raw materials are further optimized, realizing direct rolling of bars, a hot charging rate of over 80%, and a hot charging temperature of some steel grades of over 850°C. The above interface technology application and layout optimization contribute to a great reduction of energy media consumption. All energy efficiency indicators are better than those of the original production line and reach the leading level in China. 

CERI helps Hansteel New Area to build a "whole-process CSP iron and steel enterprise" with ultimate energy efficiency. 

CERI has made systematic innovations in source emission reduction, process control, end treatment, and comprehensive utilization. It has maximized energy efficiency during production, fully implemented the concept of green development, and given better play to the economic, social and ecological benefits of energy conservation and carbon reduction. It has implemented dozens of "ultimate energy efficiency" measures and the first front-end treatment technology for energy conservation and emission reduction in China's metallurgical industry in Hansteel New Area, jointly building a Grade A environmental protection performance enterprise. 

Intelligence for technology empowerment and digital intelligent future. CERI has adopted hundreds of advanced cutting-edge iron and steel technologies in the construction of Hansteel New Area, realizing intelligent control of hundreds of processes and helping Hansteel New Area to build an intelligent steel plant.
