达尔明塞得科是阿根廷唯一的一个生产无缝管的联合企业。1970年该企业将一台方坯连铸机改造成圆坯连铸机,其目的在于确立用弧形连铸机浇铸圆坯,然后经该厂新近安装的自动穿孔机和连续轧管机轧制无缝管的可行性。试生产克服了一系列困难,取得了良好成果。因此,1976年第一台曲率半径为4米的连铸机便开始生产φ110～φ140毫米的圆坯。 1977年初,新的自动穿孔机和连续轧管机投产。于是,1978年3月,第二台曲率半径为10.5米的连铸机便正式投产,浇
Dalmine-Sedco is the only Argentinean company that produces seamless pipes. In 1970 the company transformed a billet caster into a round billet caster, the purpose of which was to establish a round billet cast with an arc-shaped continuous casting machine and then rolled by the newly installed automatic piercing mill and continuous tube rolling mill at the plant The feasibility of seamless pipe system. Trial production overcame a series of difficulties and achieved good results. Therefore, in 1976 the first continuous casting machine with a radius of curvature of 4 meters started to produce round billets of φ110 ~ φ140 mm. In early 1977, the new automatic punching machine and continuous tube rolling machine went into operation. Thus, in March 1978, the second continuous casting machine with a radius of curvature of 10.5 meters was officially put into operation
