Title: Method for preventing wall-thickness deviation of steel pipe in hot stage
Inventor: IWANAGA YOSHIO
IPC: B21C37/083
Filed: 1984-08-15
Abstract: PURPOSE:To reduce the variation of wall thickness in the pipe peripheral direction by performing a draw-rolling while locally force-cooling a thicker part of the wall thickness of pipe in its peripheral direction at the 1st half side of a group of rolling rolls, in case of drawing the outer diameter of a hot steel pipe into a prescribed one by a group of rolling rolls. CONSTITUTION:A skelp (a) is heated in a heating furnace 6, and is formed into a semicircular shape by forming rolls 1 after turning its edge-part upward. Next, it is forge-welded by forge-welding rolls 2, draw-formed into a tubular shape by drawing rolls 3 and locally cooled in the pipe peripheral direction by a forced- cooling device 7 in sequence, and is further drawn by drawing rolls 4 and then draw-rolled into a prescribed pipe diameter by drawing rolls 5. In case of cooling the pipe-shaped material by the cooling device 7, the quantity of cooling water from plural nozzle headers provided to the device 7 is adjusted in accordance with the difference between the minimum wall thickness and an actual one based on said minimum wall thickness in the pipe peripheral direction, to draw the material by the rolls 4 located behind the device 7 and succeeding rolls so as to obtain the uniform wall thickness.
