PURPOSE:To prevent the penetration of a molten metal into the pore of a mold and to prevent a crack being caused on the mold by specifying the max. diame ter of the pore of the face coming into contact with the molten metal of a mold and the pore rate of a carbon mold. CONSTITUTION:In the carbon mold 1 used in case of manufacturing a metal or alloy by a continuous casting method, the pore rate of the carbon mold 1 is taken at 10%max. and the max. diameter of the pore of the face coming into contact with the molten metal 5 of the mold 1 in 0.2mm max. Both an ingot piece 6 and the mold 1 can thus be held in a good state even for use, ever along period. |
