PURPOSE:To make the entire quantity of production of the cast slabs per unit time substantially constant and make the supply capacity for molten steel and the rate of casting equal by combining and casting simultaneously the ingots cast in the directions of decreasing or increasing ingot widths. CONSTITUTION:The 1st mold casts ingots in the direction from narrow widths to broad widths and the 2nd molds in the direction from broad widths to narrow widths, that is, the entire part of the ingot width (1,2,3,-2n) requested in process rolling is bisected, and 1,2,3-n are cast with the 1st mold B, and 2n, 2n-1- n+1 are cast with the 2nd mold C by reversing the order of A. Hence, while the total ingot width of the ingots cast from both molds is maintained always constant, the ingots are cast in combination. Thereby, the supply capacity of molten steel and the rate of casting are made always substantially equal, and the maintenance of the overall quantity of production to a max. extent is made possible. |
