Cultivation special steel bar production line technological transformation project completion
Recently, the nanjing integrated iron and steel co., LTD. Enterprise bloom continuous caster reconstruction project and medium-sized factory 850 mm rolling mill rolling bar and finishing testing production line successively completed the technological transformation, and successfully put into production. The electric furnace, medium special steel bar production line technological transformation project, is the cultivation in order to further enhance the competitiveness of bar products, to build the second after plate efficiency point of the important measures, for the cultivation of special steel bar production equipment upgrade, technical documents, the variety development and market development has laid a solid foundation.
Cultivation enterprise bloom continuous caster reconstruction project is in the original scrap field rebuilding a annual capacity of 600000 tons, using international advanced technology of bloom under light pressure (320 x 480) continuous casting machine, at the same time to build a new full steel structure factory building covers an area of 14500 square meters. The project to complete on July 4, 2008 hot test, the main equipment is completed, cultivation form of electric furnace, refining, bloom continuous casting of special steel casting billet production process.
Medium-sized factory half 850 rolling mill and rolling bar project is composed of steel rolling line and finishing inspection line, adopted the advanced and mature production technology, technology and equipment. Steel rolling system is composed of 11 aircraft rolling mill, adopts flat vertical alternate rolling technology, and matches by the walking beam furnace and step cooling conveyor, etc.; Finishing detection system by blasting, skinning, acid pickling and flaw detection. The project in June this year across the heat load of steel.
