Japanese Patent JP6668567
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tundish capable of suppressing variation in molten steel temperatures among respective strands in a tundish.SOLUTION: A tundish 1 comprises: right/left/upward runners 9a, 9b; horizontal or downward runners 9c; and a strand chamber 5 with a bottom part arranged below a lower end of outlets 10c of runners 9c; and satisfies relational expressions, d≤0.3,D≤0.3,x≥0.1z+D/2,θ≤60,ztanθ-0.1z/cosθ≥H/3,ztanθ+D+0.1z/cosθ≤H,x≥0.1(z+z)+(d+D)/2 (where d: a runner 9c longitudinal diameter; d: runner 9c lateral diameter; D: runner 9a. 9b longitudinal diameter; D: runner 9a, 9b lateral diameter; x: distance from intersection between runners 9a, 9b and front surface wall 7 to intersection between extension line of casting mold injection hole 6 axis center near partition bank 8 and front surface wall 7; θ: horizontal angle at intersection between runners 9a, 9b and front surface wall 7 on strand chamber 5 lateral center side; θ: upward angle of runners 9a, 9b)SELECTED DRAWING: Figure 2A
