Abstract: PURPOSE:To make the position where the solidification of molten metal in a casting mold starts constant and to enable the control of the depth of flaws, by forming the casting mold part of a small section on the inlet side of the casting mold for horizontal and continuous casting and drawing the ingot at prescribed pitch. CONSTITUTION:A casting mold part 9 of a small section on the inlet side and a casting mold part 8 of a large section with a stepped part 7 bordering at said part are formed in a casting mold 3 into which molten metal 5 flows from a tundish 1. When an ingot 6 is drawn out by a prescribed pitch 14 upon lapse of a prescribed time after the inflow of the metal 5, the metal 5 flows freshly into the mold 3. The molten metal is cooled by a water-cooled jacket 2 and begins to solidify from the preceding end 10 of the solidified shell, thereby forming a freshly solidified shell. The next drawing is performed when the thickness of the fresh end 10' of the solidified shell is smaller than the level difference of a step part 7, thereby forming flaws smaller than the level difference at the intervals equivalent to the length of the pitch. When the freshly solidified shell extends to the part 9 beyond the part 7, the ingot 6 is drawn at the pitch larger than the length 13 of the part 9, whereby the depth of the flaws is controlled.
