曼内斯曼兄弟于1885年发明斜轧穿孔工艺,尔后又发明了周期轧管工艺。为纪念曼内斯曼兄弟发明斜轧穿孔工艺120周年,从斜轧穿孔开始,重点回顾了无缝钢管生产在1882~1937年这55年间经典轧管工艺发明及其发展的历史过程。同时列举了20世纪下半叶无缝钢管生产工艺发展过程中的几件大事,以宏扬历史成就,期盼无缝钢管工业再创辉煌。
Mannesmann Brothers invented the process of cross-piercing and piercing in 1885, and later invented the cycle-rolling process. In order to mark the 120th anniversary of the Mansman Brothers’ invention of the cross-piercing process, the history of the classical pipe-rolling process and its development during the 55 years between 1882 and 1937 was reviewed emphatically. At the same time, several important events in the development of seamless steel pipe production process in the second half of the 20th century were listed to promote historical achievements and expect seamless steel pipe industry to create greater glories.
