China new steel holding group co., LTD is one of the largest iron and steel production and trade enterprises in China, and there are six subordinate factories by holding and joint venture, seven affiliated trade enterprises. Currently our all factory employs 35, 000 people, including 730 inspection personnels, our plant has the Japan physical X-ray fluorescence spectrometer, Swizerland ARL direct reading spectrometer, microcomputer control electro-hydraulic servo universal testing machine, etc, which can be used in inspection and testing of iron, billet steel and rolled steel 40 kinds of chemical composition, mechanical property, and surface quality. Our factory adopts the advanced H-type steel complete production equipment from Italy Danieli company, the first-stage project production capability is up to 5.6 million tons, already formed the scale of 2.4 million tons and 900 thousand tons H-type steel. The leading product H-type steel includes HW, HM, HN series, which dimension is H100mm-H350mm. As a economical cross-section steel, H-type steel is widely used in industrial and civil building, railway and bridge construction, municipal construction, nuke industry, shipbuilding industry, aerospace industry, petro chemistry and expressway and so on. Otherwise our sintering plant can produce 35 million tons of sinter, 3.5 million tons of pellets every year. Our ironworks annual output of 19 million tons of hot metal. Blast furnace equipment all used PW bell-less top, Blast furnace used the hydraulic machines of clay gun in the same side and hydraulic opening machines, Axial fan with the compressor. Pulverized coal injection system used a production capacity of 33 tons/hour of the five-speed grinding, tons of pulverized coal injection amounted to 500kg of iron. Billet steel plant can produce 15 million tons, in addition to the production of ordinary carbon steel, quality carbon steel, low alloy high strength steel, but also the production of low carbon steel, X65 pipeline steel and weathering steel below. H plant has a H beam steel production line there, it can produce HW, HM, HN specifications of the three series of 19 H-beam steel and 2.8 million tons of flange beam, of which H192x198 light-gauge steel section. Our steel bar factory has a production line, spiral plate production line, can produce the national standard, Japanese standard, British standard Φ12-40mm and with ribbed steel barΦ16-50mm of the 3.3 million tons, and production of high-intensity three threads steel. And our high speed wire rod plant with high-speed wire production line, can produceΦ5.5-16mm smooth wire, Φ6.0-14mm rebar 9 million tons of steel to carbon steel, quality carbon structural steel, low alloy steel, cold heading steel, welding steel, spring steel, alloy steel and finished products are a direct rolling. Our strip plant has a 1580mm hot rolled steel production line, can produce a width of 700-1430mm, thickness 1.2-16mm of coil 6 million tons. Steel grade of plank stuff is main based on ordinary carbon steel plate structural steel, quality carbon structural steel, low alloy high strength steel.In addition, there are granulated blast furnace slag six production lines in our plant, which adopts the imported LM56.3+3S of large-scale slag roller-style mill equipment. The Six lines planed annual production capability is 7.2 million tons, with the product fineness of 450m2/kg and the granulated blast furnace slag according to GB/T18046-2008 of S75, S95.S105 standard and the BS6699 standard. CNNS takes "Maximization of Resources, service for construction" as core idea, "technological innovation" "great building internationalization" "talents enhance the quality of enterprise" as strategy, is one of the largest comprehensive building material industry group integrating scientific research, manufacture, logistics. Upon the end of 2009 group total assets had been over 6 billion US dollars.
