Zusammenfassung:A structure of burners and holes for tundish preheating is provided to reduce heat loss generated when flame of burners emits through preheating holes when performing preheating operation within a tundish. In a structure of burners and holes for tundish preheating in which burner bodies(11) of tundish preheating burners are inserted into preheating holes of a tundish cover to eject flame, the structure is characterized in that the tundish preheating burners comprise: an upper plate(21) which has a diameter larger than that of the preheating holes and is formed on an outer circumferential surface of the burner bodies to cover the preheating holes; a lower plate(31) that is separably connected to a lower portion of the upper plate and has size and shape corresponding to those of the upper plate; and a first flame barrier(33) installed on a lower portion of the lower plate and inserted into the preheating hole to seal the preheating hole.
