OREANDA-NEWS. July 01, 2011. The COREX Smelting Reduction Device Shaft Furnace Emptying Technology Method, submitted by the Fourth Overhauling Branch of MCC Baosteel Technology Services Co., Ltd. (MCCBTS), bagged the golden medal in the 23th Excellent Invention Qualification Trials at Shanghai. Meanwhile, this technology also filled the domestic gap in shaft furnace emptying technology, reported the press-centre of MCC Limited.

This Excellent Invention Qualification Trials at Shanghai, started from June 2009 and themed with Post Innovation, Energy Conservation and Emission Reduction and Promoting Development, selected 97 prized items from several thousands declared items of different industries for 2 years through media publicity, concentrated exhibition, vote online, interview reply, etc. The technology method as declared by MCCBTS was formed through summarizing the successful experiences of 7 times of the shaft furnace emptying of the furnace #1 of Baosteel Luojing Branch – the currently largest smelting reduction fining furnace – from its operation in 2006, and comprehensively considering the equipment characteristics and combining the guidance opinions from overseas experts.

It was dangerous for the emptying operation of the shaft furnace of the smelting reduction fining furnace and it was strictly required for each procedure, and any accidents may easily cause furnace internal collapse or flare up or explosion. The shaft furnace emptying technology and a series of special tools as originated by MCCBTS could minimize the danger of such task while ensuring the construction progress and construction quality. This technology not only filled the domestic shaft furnace emptying technology gap but also realized certain optimization as compared with the worldwide currently shaft furnace emptying technology. Through long term application and practices, this technology was recognized by Baosteel Luojing Branch and overseas experts.
