Abstract

PURPOSE: To manufacture the exact annular sheet with a specified inner radius and uniform thickness, by executing the hot rolling pass to obtain the steel strip whose thickness is gradually tapered to one side edge, and also, by employing the core metal with radius slightly larger than the inner radius of the annular sheet to be manufactured.
CONSTITUTION: The steel strip 1, whose one face is tapered 7 to one side edge 1a, is manufactured by the hot rolling pass; this strip 1 is continuously supplied to the spiral sheet winding pass, and is bent into spiral form taking the thinner side edge 1a as the inner diameter side and taking the thicker side edge 1b as the outer diameter side. The thickness in the direction of breadth of thus obtained spiral sheet 3 is uniformized in every part. The radius R of the core metal 2 to be used in the winding pass is settled at a radius whose circumference is longer to the extent of the weld margin to be lost at the flush butt welding than the circumference of the inner radius (r) of the aim annular sheet, and the part equivalent to the weld margin is cut away forming the flat plane 8. Hereby, since the part 8' corresponding to the plane 8 is flattened, the middle part of the part 8' is cut off and is welded into an annular form.
