Abstract
PURPOSE: To adjust the wall thickness at the end of pipe blank, and to prevent the increase of wall thickness, by reducing the diameter of the roll caliber of the plural rear stands after the tail end of the pipe blank goes out of the first roll stand, at manufacturing the pipe by continuously hot rolling on the mandrel inserted into the pipe blank.
CONSTITUTION: The pipe pushing bench includes the stands 1W9 and the pusher 10 for the mandrel 11. The rear stands 7, 8, 9, are the sizing stands, and the adjuster 14 for adjusting the roll caliber is connected to the controller 16 through the control pipe 15, and the detector 17 is connected to the controller 16 through the detecting cable 18. When the detector 17 detects that the tail end 19 of the pipe blank 13 goes out of the first stand, the controller 16 actuates the adjuster 14 through the control pipe 15. The adjuster 14 reduces the caliber diameter D formed by the caliber rolls 21, 22, 23, or the roll caliber adjustable rear stands 7W9.
