Title:
CONTINUOUS CASTING METHOD AND BELT TYPE CONTINUOUS CASTING APPARATUS
Document Type and Number:
Japanese Patent JP3217638
Kind Code:
B2
Abstract:
PURPOSE: To prevent the remaining of bulging deformation of a cast slab and to enable the casting at high velocity.
CONSTITUTION: At the time of continuously casting molten steel at ≥2.5m/min casting velocity, the vertical vibration of the molten metal surface in the mold is prevented by forming the IPI' distance L between the upper and the lower support rolls 2 of plural pairs just below the mold to ≤220mm and ≤506.V-2/1 in the relation of the casting velocity V (m/min) to guide the cast slab 3. Further, in a belt type continuous casting apparatus forming the mold part with one pair of belts 52 endlessly rotated and one pair of side dams 54 interposed at both ends in the descending part, the remaining of the bulging of the cast slab 3 is prevented to support the cast slab 3 by the support rolls 2 arranging the distance between the upper and the lower rolls to ≤180mm at the lower part of the mold 51 part.
