Abstract
PURPOSE: To decrease spread and form a pointed part to the material to be rolled, in hot rolling, by changing the number of roll revolutions of the specific stands in the required position of the material to be rolled.
CONSTITUTION: When the part to be pointed of the material 1 to be rolled reaches the final-1 stand 3, the numbers of roll revolutions of the final-2 stand 2 and and the stands on the upper stream side than this are decreased at the same rate, to apply tension to the material 1 between the final-2 stand 2 and the final-1 stand 3. If at this time the width B0 of the oval section of the material 1 on the outlet side of the final-2 stand 2 is beforehand matched to the desired width B1 of the pointed part on the outlet side of the final-1 stand 3, the spread in the final-1 stand 3 may be made nearly obsolete by lowering the number of roll revolutions in the final-2 stand 2. The pointed part 1a having thickness H1 and width B1 may be formed by the stand 3.
