    Abstract: 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.

    Abstract: The present invention provides continuous casting-milling equipment and method capable of switching between continuous and batch milling, which increase the process yield rate by reducing the portion which is unavoidably processed as scrap, when switching casting or at an initial stage. The continuous casting-milling equipment comprises: a casting unit; at least two rolling units; and a coil box arranged between the rolling units. The continuous casting-milling method comprises: a casting step for producing a slab; a first rolling step which reduces the thickness of the slab; a cutting step of cutting a predetermined distance from a front end portion of the slab at the initial stage of casting; a passing step of passing the continuously supplied slab through the coil box; and a second rolling step which reduces the thickness of the passed slab.
