摘要： A method and apparatus in a hot multi-stand tube mill for producing a thin metallic tube having end portions which corresponds to the wall thickness and diameter of the rest of the rolled tube or alternately, tapered ends. Each stand is provided with a set of three cooperating rolls arranged to form a roll pass opening. According to the tube's positioning in the mill, an appropriate additional adjustment of the rolls to decrease or enlarge the roll pass diameter is made in one or all of the last three stands. Both an initial roll setting varying means and an additional roll setting varying means cause movement of wedges abutting the roll chocks thereby causing movement of the rolls.
