板製品のための圧延方法およびそれに関する圧延ライン

Japanese Patent JP5674929

B2

Rolling method for the production of flat products, such as metal strip, which provides a production step of a thin slab with a thickness comprised between 30 and 90 mm, preferably between 35 and 70 mm, a temperature maintenance and/or possible heating step of the slab to be sent for rolling, and a rolling step with multiple passes performed in a reversing rolling mill (14) comprising at least a reversing rolling stand (15), in which at least a winding reel furnace (16a) is also present upstream of the stand (15) and a winding reel furnace (16b) downstream of the stand (15), a winding step also being provided downstream of the rolling in at least a coiler (19a, 19b) to form a relative coil of strip of a defined weight, comprised between 20 and 30 tons, and a cooling step of the strip being provided between the reversing rolling mill (14) and said at least one coiler (19a, 19b). The method provides that the thin slab is disposed, for example, sheared to size, upstream of the maintenance and/or possible heating step in order to form a segment of slab having a length equivalent, in weight, greater than that of a coil, and that, already after the first rolling pass in the reversing rolling mill (14), the thickness of the segment of slab is reduced to a value in the range of 20-25 mm so as to render it windable on the reel furnace (16b) downstream of the stand (15).
