我厂两台 R5-150×1050毫米板坯连铸机,于1970年初由西安重型机械研究所完成了设备设计,由北京钢铁设计研究总院、上海冶金设计院、上海工学院及上钢一厂完成了各种配套工程设计,1972年开始试生产。初期浇铸的板坯,表面有纵向裂纹,设备上也存在一些问题,严重阻碍着连铸新技术在我厂生产中的应用。1973年初,治金部、一机部联合组织攻关组,试验改进了部分设备,采用了新的工艺措施,解决了技术难关,试浇新钢种取得成功。1974年11月,两部又在上海联合主持召开鉴定会,之后该两台连铸机投入了正常生产。1978年,我厂又自行改进仿制了第三台。十多年来,三台连铸机在我厂生产中发挥了很大的威力,也可以说是连铸技术的应用,收到了突出的经济实效。具体有:
I plant two R5-150 × 1050 mm slab caster, in early 1970 by the Xi’an Institute of Heavy Machinery completed the equipment design, the Beijing Iron and Steel Design and Research Institute, Shanghai Metallurgical Design Institute, Shanghai Institute of Technology and a steel Factory completed a variety of supporting engineering design, 1972 trial production. The initial casting slab, the surface longitudinal cracks, there are also some problems on the device, seriously hindered the continuous casting of new technologies in our plant production applications. At the beginning of 1973, the Ministry of Governance and the Ministry of Machinery jointly organized the research group to improve some of the equipment and adopted new technological measures to solve the technical difficulties and to test the success of the new steels. In November 1974, the two companies jointly held an appraisal meeting in Shanghai, after which the two caster machines were put into normal production. In 1978, our factory also improved its own imitation of the third. For more than a decade, three continuous casting machines have played a great role in the production of our plant. It can also be said that the application of continuous casting technology has received outstanding economic results. Specifically:
