Abstract
PURPOSE:To make the height of a casting machine half and decrease casting defects by making the leveling internal strain rate of a slab at each leveling point of the multipoint leveling curving type continuous casting machine less than the specific value. CONSTITUTION:Casting is performed by making the leveling internal strain rate epsilonN expressed by the formula within a range of <=0.35%. The leveling points of a leveling region are 5 points P1-P5, and the curving radii R1-R5 are of respectively different values, becoming successively larger R1-R5. For example, For R1 is made 5800mm. and R5 7100mm.. Here, killed steel of 0.20% C content sizing 410X1,700mm.is cast at a speed of 0.5m/min. The frozen shell thickness at the leveling point P1 is 110mm. and the rate of freezing is in a 40-70% range, and in this case, it is about 54%. If from these conditions the leveling internal strain rate is obtained, by the formula it is 0.28%, below the specific 0.35%. The respective strain rates of P2-P5 become nearly the same values as well. The curving radii at the respective leveling points are beforehand so determined as to satisfy the formula. The height of this curving type continuous casting machine is about 6m, less than about half that of conventional types.
