Title: Production of stainless seamless steel tube
Inventor: ANRAKU TOSHIRO
IPC: B21B3/02
Filed: 1994-09-26
Abstract: PURPOSE: To prevent curburizing of tube inner surface by heating while filling the inside of tube with gas containing water vapor at the time of reheating of tube stock after mandrel rolling or at the time of auxiliary heating for solution heat treatment of tube after finish rolling not through reheating. CONSTITUTION: When a hollow tube stock 4a of stainless steel is produced to a seamless steel tube with use of a lubricant containing carbon by a mandrel mill 5, before a tube stock 4a after mandrel rolling is subjected to finish rolling while the inside of the tube is filled with the gas containing 10vol.% water vapor, the tube is subjected to reheating/rolling and then solution heat treatment. Further, when a rolled tube stock is subjected to finish rolling without reheating, the inside of the tube is subjected auxiliary heating while filling the inside of the tube with the gas containing 10% vol water vapor. By this method, the lubricant stuck to the inner surface of tube is reacted with water vapor to be decomposed, thus, carburizing is prevented.
