The utility model discloses an embedded swing nozzle prefabricated part, which comprises a prefabricated part main body, wherein the shape of the end surface of the prefabricated part main body is of an arc shape corresponding to a swing nozzle. One end surface of the prefabricated part main body protrudes outwards from the bottom of the arc to form a step. The height of the step is one second of the bottom height of the prefabricated part main body. Two grooves which penetrate through the two side end surfaces are arranged on the bottom surface of the prefabricated part main body. The shape of the grooves is triangular. In the utility model, the swing nozzle prefabricated part which is high-temperature sintered is embedded into the swing nozzle part, then castables is poured at the periphery thereof to make the swing nozzle to form a composite structure, while the step at one end surface of the prefabricated part main body, which is formed at the bottom of the arc, is poured and covered by the castables, so the prefabricated part and the swing nozzle are integrated into a whole body. The utility model has the advantages of energy conservation, durability and convenient maintenance.
