1983年年初日本住友公司在海南厂新建的114mm限动芯棒连轧管机组配备了一台锥形辊穿孔机,年生产能力达到50万吨以上。这一套由美国Aetna standard公司设计、日本住友重机制造的连轧管机组具有很多特点,其中锥形辊穿孔机(见图1的示意图)是最引人注目的。其实,锥形辊穿孔机(也称菌式穿孔机)早在本世纪初就已经出现了。
Early in 1983, Sumitomo Corporation in Hainan plant new 114mm limited mandrel mill equipped with a cone roll piercing machine, the annual production capacity of 500,000 tons or more. This set of design by the United States Aetna standard company, Japan’s Sumitomo heavy machinery manufacturing pipe rolling unit has many features, including the cone roller piercer (see the schematic diagram of Figure 1) is the most striking. In fact, tapered roller piercing machine (also known as bacterial piercing machine) as early as the beginning of this century has emerged.
