Beschreibung
Zusammenfassung:	A method for horizontal type continuous casting, which comprises: withdrawing a cast strand from a mold provided horizontally at the lower part of a tundish at a prescribed withdrawing speed for a prescribed period of withdrawing time; pushing back the cast strand for a prescribed period of push-back time in the direction opposite to the direction of withdrawal; withdrawing the cast strand again from the mold at the prescribed withdrawing speed for the prescribed period of withdrawing time; and repeating the withdrawal and the pushing back, the distance of the withdrawal being longer than that of the pushing back, to thereby intermittently withdraw the cast strand from the mold. The method being characterized by comprising: limiting the prescribed period of push back time within the range of from 0.1 to 0.6 seconds, thereby preventing breakouts and cracks from occurring in a trailing end portion of a solidified shell of the cast strand in the mold.
