江西洪都钢厂与东北工学院共同承担的江西省重点科研项目“不对称3辊异径轧机热连轧薄带钢新技术”研究成果,于1991年12月25日通过专家鉴定。 洪都钢厂利用该技术取得了降低轧制压力49％～62％,提高轧薄能力和产品精度(最小轧薄厚度由原来2辊同径轧机时的2.75mm减薄到了1.5mm) Jiangxi Hongdu Steel and Northeast Institute of Technology shared the key research project in Jiangxi Province “Asymmetric 3-roll reducer hot strip thin steel new technology” research results, in December 25, 1991 through expert identification. Hongdu Steel made use of the technology to reduce the rolling pressure by 49% ~ 62%, improve the thinning ability and product accuracy (minimum thinning thickness from the original 2-roll same diameter rolling mill when the 2.75mm thinning to 1.5mm)
