南钢在“七五”期间要立足于继续挖潜、改造,建成生产钢、铁、材各60万吨的综合生产能力。调整后的轧钢产品,除生产中小型材、薄板外,建设一套年产20万吨的高速线材轧机,产品规格为Φ5.5—13毫米的线材。也可对现有650×3轧机进行技术改造,适当增加设备后可以生产一种高效的经济断面的H型钢。在1990年以后,可把南钢建设成年产100万吨钢的规模,拟建第二炼钢系统,即走海绵铁—电炉炼钢—连铸—1200热轧带钢轧机的道路。把南钢建成既有转炉系统,又有电炉系统,具有一定装备水平的中型钢铁联合企业。
During the “Seventh Five-Year Plan” period, Nangang will continue to tap the potential and transform itself into an integrated production capacity of 600,000 tons of steel, iron and steel products each. The adjusted rolling products, in addition to the production of small and medium-sized sheet, sheet, the construction of an annual output of 200,000 tons of high-speed wire rod mill, product specifications Φ5.5-13 mm wire. It is also possible to retrofit the existing 650 × 3 mill with the addition of equipment to produce a highly efficient H-section of economical section. After 1990, it is possible to build Nangang Steel into a scale of 1 million tons of steel per annum and construct a second steelmaking system, namely, the road of sponge iron-electric furnace steelmaking-continuous casting-1200 hot strip mill. The steel built into the existing converter system, there are electric furnace system, with a certain level of equipment, medium-sized iron and steel enterprises.
