摘要： A method and device for rolling tube to a smaller diameter, with which at least one area of the outside of the tube is brought into contact with at least one roll rotatable around its axis, whereby this roll and the tube are brought into a relative movement with respect to each other. The contact surface of the roll and tube, considered between two planes spaced in a longitudinal direction of the tube, lies at an angle to the longitudinal axis of the tube.The contact surfaces of the rotatable rolls with the deformed tube follow one or more spaced spirals with conically rolled tube or one or more helical lines with cylindrical rolled tube. The position of the effective roll surfaces is adjustable with respect to the longitudinal axis and the transverse axis of the tube, and the contact area with the one or more rolls is heated to the roll temperature before the rolling.
