Baosteel Starts Up World's Largest Corex Ironmaking Plant – First Implementation of Corex Technology by Siemens in China
Linz/Austria, 2007-Nov-16
The Chinese steel producer Baosteel Pudong Iron and Steel Co. Ltd. (For Short Pudong steel) at Luojing, near Shanghai started up a Corex C-3000 plant, with a nominal production capacity of 1.5 million tons of hot metal per year. The project was completed under the management of Siemens Metals Technologies within only 29 months from the contract signature. Substituting coke, a wide range of coals can be directly used in the Corex Process for the smelting-reduction operations, considerably reducing raw-material costs and environmental emissions. Corex fully meets the extremely strict environmental regulations which were imposed by the municipal government as a precondition for the reconstruction of the steel works. The top gas from the Corex plant is used a combined-cycle electrical power station and also for heating purposes throughout Baosteel's steel works.
Baosteel Group Corp. is one of the largest steel producers in China. Pudong steel (the former Shanghai No.3 steel company), a subsidiary of Baosteel Group, was rebuilt at Luojing in the Baosteel industrial area on the western outskirts of Shanghai due to the relocation projects for 2010 World Expo. With consideration to the inherent economical and environmental advantages offered by the Corex process, Baosteel decided to base their iron production on this technology instead of on the conventional blast-furnace route. The tapped hot metal is comparable in quality to that produced in a blast furnace.
Siemens Metals Technologies was awarded the contract from Baosteel for the supply of the Corex facility in June 2005. The project scope included the supply of the complete process engineering, engineering of key plant areas, the engineering and supply of core equipment and components such as the coal dryers, hot-gas generator, oxygen burners, screw conveyors for the reduced iron and coal, two Gimbal-charging systems (one for the charging of burden into the reduction shaft and one for the charging of coal into the melter gasifier), the gas-cleaning equipment and recycling systems, cooling-gas compressors, gas-gate valves, electrical equipment for Level 1 and Level 2 automation and also core instrumentation. Advisory services for local manufacturing, engineering erection and plant start-up as well as training rounded off the Siemens scope of supply.
In the course of this project which lasted 29 months, over 5,000 pilings were installed and 10,200 tons of steel structure were erected – 100 tons more than the weight of the Eifel Tower. The height of the Baosteel Corex tower is 118 meters, which is 15 meters higher than the Statue of Liberty in the U.S.A. More than 4,000 on-site working personnel were involved in the construction of the Corex plant. According to Christian Böhm, Sales Manager for Smelting-Reduction and Direct-Reduction Technology, “That a project of this size and complexity could be completed within such a short time period, especially when it involves an innovative ironmaking technology, is a testimony of the outstanding efforts, coordination and the will to succeed by all parties involved.”
In the plant commissioning period the already respectable process parameters of Baosteel's Corex plant will be further optimized to maximize the economical and environmental advantages.
