Dragons special steel bar production line technological transformation project completion
Recently, Nanjing Iron & Steel United Co., Ltd. Furnace bloom caster reconstruction project as well as medium-sized factory 850 mm semi-continuous bar rolling mill and finishing production lines have been completed testing the technological transformation, and smooth operation. The furnace - medium-sized steel bar production line technological transformation project is the Dragons to further improve the competitiveness of bar products, to build a second plate after benefits anchor an important measure for the Dragons steel bar production equipment upgrades, to mention technology, product development and market development has laid a solid foundation.
Dragons Furnace bloom caster reconstruction project is rebuilt in the original site scrap an annual production capacity of 600,000 tons, using international advanced soft reduction bloom (320 × 480) continuous casting machine, while an area of 14,500 new meters of all-steel plant. The project to July 4, 2008 to complete the main heat test equipment, after the completion of the formation of an electric furnace Dragons - Refining - bloom continuous casting of steel billet production process.
850 medium-sized plant engineering from the bar rolling mill semi-rolling production line testing and finishing production line components, the use of today's advanced and mature production process, technology and equipment. Rolling mill system consists of 11 components, the use of alternating vertical flat rolling process, and with a walking beam furnace and cooling bed step-like; finishing inspection system by the blasting, stripping, pickling, testing and other processes composition . The project in June this year, the full range of thermal overload steel.
