PURPOSE:To prevent the disturbance of molten surface and the entrapment of oxide film and to obtain the titled pouring apparatus improving the product quality by forming a molten metal basin on the way of a slit nozzle attached to a tundish and making smoothness of the suitable molten metal in the above molten metal basin to directly pour the molten metal into a pool in weirs. CONSTITUTION:At the time of supplying the molten metal in a ladle 9 into the tundish 1, the molten metal in the tundish 1 is flowed into a slit 4 of the slit nozzle 3 through each pouring hole 2. And, the molten metal flowing in the slit 4 from each hole 2 as line-state, is stored in the molten metal basin 6 and the line-state molten metal flowing is perfectly lined up toward width direction and after buffering and uniformizing the direction and velocity of flowing, the molten metal is smoothly flowed into the pool 8 in the weirs above the cooling rolls 7, 7 from the slit 4 below the molten metal basin 6. In this case, as the lower part of the nozzle 3 is dipped in the pool 8, the molten metal flowed out from the slit 4 is directly flowed in the pool 8 and the molten surface is not disturbed and the molten surface in the pool 8 is stabilized and also the flow of molten metal is stabilized and the quality of the product is improved.
