PURPOSE:To prevent the development of solidified shell on a short side mold by arranging projection having shape along a long side mold at the short side mold position near the part brought the short side mold into contact with the long side mold. CONSTITUTION:In the continuous casting mold, the projection 4 having the shape along the long side mold 5 at the short side mold position near the part brought the short side mold 1 into contact with the long side mold 5 is arranged. This projection 4 is projected in high temp. molten metal 12 having at least the solidified temp. or higher of the molten metal 12 and three directions around the projection is surrounded with this high temp. molten metal 12. Further, the volume of the projection 4 is far small as compared with the molten metal 12 around the projection 4. Therefore, at the time of pouring the molten metal 12 around the projection 4, the projection instantly comes to the same temp. as the molten metal 12 and hot spot having the same temp. as the molten metal 12 is formed on the short side mold 1. As the temp. of this projection 4 raises, it has effect, which cooling from the long side mold 5 as cooling body is reduced. In this result, the development of the solidified shell on the surface part of the short side mold 1 is surely prevented. |
