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).

摘要： Rolling method in a rolling line (10), to produce strip with a thickness varying from 0.7 mm to 20 mm, for all qualities of steel which can be cast in the form of thin slabs with a thickness comprised from 30 mm to 140 mm, the line (10) comprising at least: a continuous casting device (1 1); a tunnel furnace (15) for maintenance/equalization and possible heating; a rolling train consisting of a roughing train comprising from 1 to 4 rolling stands (18a, 18b, 18c) and a finishing train comprising from 3 to 7 stands (21a-21e); a rapid heating unit (20), with elements able to be selectively activated, interposed between the roughing train and the finishing train. For each lay-out of the rolling line (10), the position of the rapid heating unit (20) which defines the number of stands (18a, 18b, 18c) which form the roughing train, disposed upstream of the unit (20), and the number of stands (21a-21e) which form the finishing train, disposed downstream of the unit (20), is calculated as a function of the product of the thickness and speed of the thin slab. The product is in turn a function of the hourly productivity in tons/hour desired to be obtained, and is made to work either in coil-to-coil mode, or in semi-endless mode or in endless mode. One of the three modes of the rolling process is selected according to the quality of the steel produced, to the maximum casting speed possible for the quality of steel, to the final thickness of the strip and to the production cost.

摘要： Multifunctional rolling stand (10) and relative method of use, suitable for rolling /forging large plates, large blooms, large round pieces and other large-size semi-worked products, for example ingots or similar products. The compression force can reach up to about 6000 tonnes in the case of ingots, depending on the type of product being worked and on the reduction ratio to be obtained. Thanks to these high forces in play, which allow to obtain compressions comprised between 100 and 150 mm, the rolling stand (10) according to the present invention is similar to a forge so that the internal porosities of the product are eliminated.
