Abstract
PURPOSE:To partially apply the drawing work to the rod material traveling in the rolling line, by fixing the caliber of special shape and size to the drum of the rolling roll being built in the frame movable perpendicularly to the rod material, and by controlling the frame speed, etc. CONSTITUTION:The rod material 1 produced from the rolling mill travels passing the center line 2 of the pass. The drawing apparatus 3 is moved synchronously with the movement of the material 1; at the moment of the start of the drawing work, the moving speed and timing of movement of the apparatus 3, and the mutually reverse rotational speeds and phases of the rolling rolls 4, 5, are controlled so as to locate the entrances 15, 16, of the calibers 11, 12, at the shape's transition zone 19. The calibers 11, 12, possess the mutually reverse twisting angle and the circumferential length equal to the length l2 to be subjected to the drawing work. At the end point of the drawing work, the material 1 possesses the form being drawn from the diameter d1 to diameter d2 over the length l2. During this period of drawing work, the center of the material 1 makes no transverse shift.
