PURPOSE:To eliminate the trouble occuring in the deformation of a stationary mold wall, sticking to a billet, generating of excessive sliding resistance, etc. with a continuous casting device for a thin plate using a rotary casting mold by pressing the non-cooled stationary casting mold to the outside circumferences in the projecting parts at both ends of the rotary casting mold. CONSTITUTION:The molten metal 2 poured into the molding space enclosed of the four sides, i.e., a cylindrical part 3a and projecting parts 3b of a rotary casting mold 3 and a stationary casting mold 5b is cooled and solidified by the above-mentioned walls then the molten metal is drawn out as a billet 1 by pinch rolls 6a, 7a. The mold 5b is not cooled and particularly in the stage of casting a material having a high solidifying point, heating elements 4f are embedded in a base 4e to heat positively the mold 5b to prevent solidification of the molten metal 2 from the side of said mold. then the billet 1 begins to grow from the mold 3 side and the growth arrives at the mold 5b wall in the area near the outlet of the mold 5b. The need for a mold belt is thus eliminated and the trouble occuring in the deformation of the stationary mold walls, sticking to the billet, generation of excessive sliding resistance, etc. is eliminated. |
