PURPOSE: A tuyere assembly is provided with a design that protects against a gas flow or molten metal when molten metal is manufactured. CONSTITUTION: A tuyere assembly comprises a tuyere(10), an oxygen intake pipe(20), and a nitrogen intake pipe(30). The tuyere has an opening. The oxygen intake pipe is installed in the opening of the tuyere and constitutes a partition surface and a separation space. The oxygen intake pipe blows gas with oxygen into the tuyere and has multiple support units which fix the oxygen intake pipe to the inside the separation space. The nitrogen intake pipe blows nitrogen gas to the tuyere through the separation space.
