关于鼓形穿孔机和锥形穿孔机的讨论

从锥形穿孔机的发展历史出发,比较了鼓形和锥形穿孔机的变形特点、主要工艺技术指标、投资和生产成本。强调指出:锥形穿孔机和鼓形穿孔机不是彼此淘汰的关系;穿孔机机型选择要综合考虑供坯条件、工艺要求和经济等因素,不能一概而论;配有鼓形穿孔机或锥形穿孔机的无缝钢管生产机组,都不是生产高合金钢管的最佳选择。

Discussion on Drum-type and Cone-type Piercing Mills

Based on a review of the evolution of the cone-type piercer, a comparison is conducted between the drum-type piercer and the cone-type piercer in terms of the deformation features, main technological indexes, investment and production cost.As a result, it is pointed out that neither of the two different types of piercers is the substitution for each other.Choice of the proper piercing mill depends on all the elements involved such as billet supply conditions, technological requirements and relevant economic...
