1.前言三明钢铁厂小轧钢车间,于1980年搬迁投产后,技术上年年有进步。1981年生产φ8、φ10mm盘条15493t,1985年已增长到43136t。为了用60mm方坯轧制φ6.5mm线材,生产适销对路的产品,厂领导决定进行适当改造,以提高经济效益,进一步增强企业活力。 2.改造方案经对几种设想方案的分析比较,决定将原φ315mm二连轧改为四连轧,即K_7～K_(10)连轧。改造前后的机列布置如图1所示。 2.1 方案的优缺点
1. Introduction Sanming Iron and Steel Plant, a small rolling workshop, moved to production in 1980, the technical progress over the years. In 1981 the production of φ8, φ10mm wire rod 15493t, 1985 has grown to 43136t. In order to use 60mm billet rolling φ6.5mm wire, produce marketable products, the factory leadership decided to make appropriate changes in order to improve economic efficiency and further enhance the vitality of enterprises. 2. Reform program After several scenarios for the analysis and comparison, the decision to the original φ315mm two continuous rolling into four continuous rolling, that K_7 ~ K_ (10) continuous rolling. Before and after the transformation of the machine layout shown in Figure 1. 2.1 program advantages and disadvantages
