<p><P>PROBLEM TO BE SOLVED: To provide a monitoring apparatus etc. of manufacturing conditions for seamless pipes which enables quick correction of manufacturing conditions during operation of seamless pipe manufacturing equipment. <P>SOLUTION: The manufacturing condition monitoring apparatus 20 for seamless pipes is characterized in that it comprises an ultrasonic thickness gage 4 installed at a delivery side of a piercing unit that manufactures a pipe S by piercing and rolling a billet B, and measures thickness of the pipe S manufactured through the piercing unit, a thermometer 5 installed at the delivery side of the piercing unit and measures surface temperature of the pipe S manufactured through the piercing unit, and an arithmetic processing display means 6 which displays thickness distribution in the circumferential direction of the pipe S and surface temperature distribution in the circumferential direction of the pipe S, based on the thickness of the pipe S measured by the ultrasonic thickness gage 4 and the surface temperature of the pipe S measured by the thermometer 5. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
