继韶钢转炉炼钢厂2号连铸机高效化改造成功之后,1999年元月30日1号连铸机高效化改造又获得成功。在改造2号机取得经验基础上,1号机从元月21日停机,30日投入运行,仅仅用10天时间,比2号机又缩短了3天。1号机的施工、安装、调试和试运转都比2号机顺利得多,因此,一次开浇成功。目前该机运行平稳,钢坯平均拉速在2.5m/min左右,最高拉速接近3m/min,自动配水仍然良好,钢坯质量、节能降耗、中间包寿命、产量(日、班)等主要技术经济指标比改造前有很大提高。
Following the success of Shaoxing No.2 continuous casting machine at Shaoguan Iron and Steel Co., Ltd., the high-efficiency continuous casting machine No.1 was successfully rebuilt on January 30, 1999. On the basis of experience gained from the transformation of PM 2, PM 1 stopped from January 21 and was put into operation on the 30th. It took only 10 days and was 3 days shorter than that of PM 2. The construction, installation, commissioning and commissioning of Unit 1 were much smoother than Unit 2, so a pouring was successful. At present, the machine runs smoothly, the average pulling speed of billet is about 2.5m / min, the maximum pulling speed is close to 3m / min, automatic water distribution is still good, the quality of billets, energy saving, tundish life, Economic indicators than before the transformation has greatly improved.
