Title:
ストリップを圧延するための方法
Document Type and Number:
Japanese Patent JP4602489
Kind Code:
B2
Abstract:
The method concerns production of a rolled strip either in a rolling section with at least two roll stands with horizontally adjustable upper and lower working rolls (which act alone or are supported directly or via intermediate rolls on support rolls), or in a reversing stand with at least two passes. At least in one region of the strip the target nonplanarity profile is predetermined over the strip width and compared with the measured nonplanarity form. The resultant difference is calculated. The available mechanically or physically acting control elements are employed to minimise this difference as far as possible. Also claimed is the apparatus comprising at least two of the following control elements: (a) movable working rolls (10, 11) or their bending units (13); (b) means for pair-wise crossing of the working rolls and the support rolls (9); (c) zone cooling (15) of the working rolls; (d) thermal covers (18) for working rolls; (e) strip edge heaters (14); (f) strip edge coolers (16); and (g) strip edge lubricators (17).
