Abstract

PURPOSE:To make it possible to continuously cast slabs of different compositions from molten steel of one heat by adding at least one kind of alloy elements to the molten steel in a tundish, in a continuous casting of steel. CONSTITUTION:Molten steel is supplied into a tundish 3 via a nozzle 2 from a ladle 1. When the molten steel level 5 in the tundish becomes steady, pure metals or alloy iron of C, Si, Mn and Ni, for example, high-carbon ferromaganeses of <=2mm., are added continuously thereto from an alloy adding device 4. During this time, joint working of a sequence block method being a conventional method is done, thence the whole strand is steadily cast. When the casting is finished, the slabs I-IV of the compositions different from those of the molten steel in the ladle are obtained from the molten steel of one heat. In order to prevent slag from entering the alloy-added portions, partitioning the tundish into two or more blocks A-C by refractory materials 9 having holes 10 and performing the addition of alloys in the B block are sometimes practiced.
