【発明の名称】熱間ストリップタンデム圧延ライン
Document Type and Number:
Japanese Patent JP2583481
Kind Code:
B2
Abstract:
A metallic strip is hot-rolled in a succession of roll stands arranged in a row by passing the strip longitudinally in a travel direction through the stands. The strip is then compressed in the upstream stands to substantially reduce its thickness measured perpendicular to the travel direction and parallel to the strip while substantially increasing its width measured perpendicular to the travel direction and transverse to the strip. Then in the downstream stands it is compressed and tensioned without substantially increasing its width to level it and stretch it longitudinally in the travel direction. With standard steel strip this critical thickness is about 12 mm. The local band thickness is measured downstream of the upstream roll stands and the furthest downstream stand of the upstream stands is operated to eliminate any nonuniformities in thickness thus detected. The nonuniformities are detected by comparing the local band thicknesses detected with standard set-point thicknesses.
