Title: Manufacture of thick steel pipe having large diameter
Inventor: KATSUMATA TAKESHIGE
IPC: B21C1/26
Filed: 1984-06-15
Abstract: PURPOSE:To straighten an uneven thickness, and to improve a yield by forming a temperature difference in the pipe peripheral direction by cooling a thin thickness side of a bottomed pipe, and thereafter, reducing the inside of a die by a mandrel. CONSTITUTION:A bottomed pipe 5 is obtained by operating a press machine 10 and pushing a piercing mandrel into a steel ingot. In this case, an uneven thickness is generated inevitably on the bottomed pipe 5. This bottomed pipe 5 generating an uneven thickness is heated to a prescribed temperature by a reheating furnace, and thereafter, a cooling water 18 is jetted to the thin thickness side of the bottomed pipe 5 from a cooling water supply pipe 17, and a temperature difference is generated in the pipe peripheral direction. When the bottomed pipe 5 is made to reduce the inside of a die 15 by a punching mandrel 14, the bottomed pipe 5 having an equalized thickness is obtained by a difference of deformation resistances of the thin part of a low temperature and the thick part of a high temperature. According to this method, the uneven thickness is straightened and also the yield is improved.
