Abstract: PURPOSE:To prevent the generation of the transverse crack of an ingot in the stage of casting continuously a molten steel by supplying gaseous hydrocarbon to the spacing between the inside wall of a casting mold and solidified shell. CONSTITUTION:A path 4 for supplying gaseous hydrocarbon is formed to the inside of the wall surface of the casting mold and is communicated with many small hole-like blow-off ports 5 opened to the inside surface of the mold 1. The ports 5 are formed in the position lower than the molten metal surface position 9 of the molten metal 8 to be poured into the mold 1 via an immersion nozzle 7 from a tundish, more preferably in the position of about 20-250mm below the molten metal surface over the entire circumference of the mold 1. The gaseous hydrocarbon such as propane or butane is supplied from a gas supply source through a piping 6 and a supply part 4 to the spacing 13 between the solidified shell 11 of the ingot 10 and the inside surface 12 of the casting mold from the ports 5. The gas is cracked by the heat from the shell 11 side and the cooling effect of the shell 11 is increased by not only the sensible heat of the gas but also the heat absorption by the cracking thereof. The resistance of the heat extraction and the fluctuation thereof are decreased in the view point of the mold side and since the cooling of the initial shell 11 is thereby made uniform, the transverse crack of the ingot is effectively prevented.
