Title: Rolling plug for seamless tube and manufacture of seamless tube
Inventor: YORIFUJI AKIRA
IPC: B21B25/00
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a plug with much more improved life time than in the conventional are under a severe condition of being constantly exposed to high temperature and high load by changing a part of plug located at the outermost surface of plug with ceramics. SOLUTION: At the time a piercer plug is used as an elongator plug or reeler plug, only so long as, e.g. a part of the latter half of working part 11 to reeling part 12 a part of reeling part to parallel part 13 or the like is changed with ceramics, a life time nearly equal to that of a plug wholly made of ceramics is expected. Consequently, as long as the joining strength between ceramics and other material is maintained above the allowable level according to the condition of using plug, it will do as well to have a part of plug itself which is naturally foreseen to be most severely worn out in the outermost surface of plug, as necessary, made of ceramics and to change the other part with the other material such as steel, carbon steel or the like.
