DEVICE AND METHOD FOR MONITORING MANUFACTURING STATUS OF SEAMLESS PIPE AND SEAMLESS PIPE MANUFACTURING FACILITY

摘要

It is an object of the present invention to provide a monitoring apparatus and the like of seamless pipe or tube production conditions which enable to quickly correct production conditions during operating the manufacturing facilities of a seamless pipe or tube. The monitoring apparatus 20 of production conditions according to the present invention comprises an ultrasonic thickness meter 4 which is installed on the exit side of a piercing-rolling mill 10 piercing and rolling a billet B to produce a pipe S and measures a thickness of the pipe S produced by the piercing-rolling mill 10, a thermometer 5 which is installed on the exit side of the piercing-rolling mill 10 and measures a surface temperature of the pipe S produced by the piercing-rolling mill 10, and a computing and displaying device 6 which displays a thickness distribution in a circumferential direction of the pipe S and a surface temperature distribution in a circumferential direction of the pipe S based on the thickness of the pipe S measured by the ultrasonic thickness meter 4 and the surface temperature of the pipe S measured by the thermometer 5.
