Abstract
PURPOSE: To diminish the edge drop and to improve the product quality, by installing at least a couple of vertical rolls on the inlet side of the finishing mill, and by rolling the material with vertical rolls according to the specified mathod, at hot rolling the material.
CONSTITUTION: The vertical reducing rolls 3a, 3b, for rolling the material 4 in the direction of breadth, and the work rolls 2a, 2b, of the finishing mill for rolling the material in the horizontal direction just following to the vertical rolls 3a, 3b, are arranged; hereupon, rolls 3a, 3b, are previously adjusted so as to make their rolling reduction to be 1/2 or less of thickness of material 4 on the inlet side. Hereby, the material 4 with the sectional profile like as the full line A, is rolled in the direction of breadth; and the both edges of material 4 are protruded upward and downward as shown by the full line B; and then, the material 4 is rolled with the work rolls 2a, 2b, into the product with good parallelism as shown by the chain line C. As a result, the finished product of excellent quality with extremely small edge drop can be obtained.
