Short-flow rolling device and method for seamless pipe

Abstract

The present invention provides a short-flow rolling device and method for a seamless pipe. The device includes a rolling mill, a transport table and an inner and outer wall cooling unit. In the present invention, by arranging the inner and outer wall cooling unit, a seamless pipe is obtained after being rolled by the rolling mill, and when the rolled pipe enters the transport table and one end of the pipe is aligned with a spray ring, the transport table stops transporting the pipe to keep the pipe still. At this time, a motor I drives a rocker I to rotate, and a telescopic rod II coincides with an axis of the pipe; and telescopic rods I and the telescopic rod II extend synchronously, and spray heads I and spray heads II simultaneously cool an outer wall and an inner wall of the pipe.
