Abstract

PURPOSE:To decrease the formation of the fish tails specific to rolling of slabs, etc. by broadside rolling reduction by using caliber rolls and press dies properly in each rolling pass. CONSTITUTION:A rolling mill is constituted of vertical rolls 22 having calibers 1 and press dies 21. First, a material 20 to be rolled is fed into the rolling mill and the preceding end thereof is pressed (4-a) with the dies 21. Thereafer, the dies are changed over to the rolls 1, by which the material is subjected to rolling by broadside rolling reduction (40-b) for the 1st pass. Again the rolls are changed over to the dies 21 and the succeeding end of the material 20 is pressed (4-c). Further the dies are changed over to the rolls 1 and the material is subjected to rolling by broadside reduction (4-d) for the 2nd pass. Thereafter the material is rolled by broadside rolling reduction until necessary width is obtained, and the required pressing is completed with the least times of passes.
