A metallurgical apparatus for cutting a nozzle for cutting a flame, characterized in that the preheated oxygen passage is an inverted cone and the gas passages inside the cutting nozzle are not in communication with each other, The annular cavity at the nozzle outlet. The utility model has the advantages of simple structure, safe operation and convenient operation, avoiding the flame cutting of the hot continuous casting billet, splashing the slagging and cutting the nozzle outlet gas (or preheating the oxygen) channel, preheating the oxygen back to the gas pipeline and tempering; To overcome the phenomenon of metal slab cutting, reducing the consumption of metal blanks.
