A tundish cover of a continuous casting machine is provided to control the inside oxygen of the tundish less than 0.6ppm, thereby preventing the formation of inclusion in the tundish. A tundish cover of a continuous casting machine comprises a main body(110) shielding the top of a tundish, an inert gas supply pipe(120) installed on the bottom surface of the main body facing the inside of the tundish, and an injection nozzle(130) installed on the inert gas supply pipe. The main body has a molten steel inlet(112) in which a shroud nozzle is inserted and a tip(114) in which a preheating burner is inserted. The inert gas supply pipe is arranged around the molten steel inlet and the tip.
