Abstract:
1. A process for the continuous casting of flat metal products, comprising: pouring a molten metal into a mold; continuously extracting and guiding an externally solidified cast product from the mold using a battery of support rolls in a secondary cooling zone downstream of the mold; and subjecting the cast product extracted from said mold to an electromagnetic stirring by a travelling magnetic field acting in a segment zero of said secondary cooling zone by at least two stirrer-rolls that are present at least within said battery of support rolls and that generate magnetic fields travelling in a same direction, to obtain the cast product having a solidification structure predominantly of the equiaxed type, wherein the diameter “D” of said stirrer-rolls approximately satisfies the equation: 2D+e=3d+2e, with “d” being a diameter of said support rolls and “e” being a free space between two consecutive rolls, and in which said segment zero is configured to insert, into the battery of support rolls, four rolls of said diameter “D”, including at least two stirrer-rolls and two dummy rolls, said four rolls being placed in a group at a same level, two on each broad face of the cast product.
