Date Feb. 13, 1986.In continuous casting of a non-ferrous metal melt by a gas-pressure impartation method, the cast skin of a large size ingot is usually impaired by the chilling effect of a mold, and it is difficult to stably produce a large size ingot. This difficulty is overcome by controlling the quantity of gas inflow in accordance with the quantity of the light emitted from a light source provided below a mold and laterally to an ingot, which light reaches a separate chamber for gas-pressure impartation. |
