A converter oxygen lance nozzle

Abstract

This utility model relates to a converter oxygen lance nozzle, including a nozzle crown, an oxygen spray pipe, an oxygen distribution plate, a baffle plate, an outer connecting pipe, an intermediate connecting pipe, and an inner connecting pipe. The annular channel between the inner and intermediate connecting pipes serves as the water inlet passage, and the annular channel between the intermediate and outer connecting pipes serves as the water return passage. One end of the baffle plate's outlet has a convex structure, and an arc-shaped transition section is provided between the convex structure and the baffle plate body. The side of the arc-shaped transition section facing the nozzle crown has a concave water inlet vortex, and the other side has a water return vortex. Using a baffle plate with both water inlet and return vortexes effectively increases the cooling water flow rate, enabling faster removal of heat from the nozzle tip, thereby improving the nozzle's cooling effect, extending its service life, and ensuring the converter's smelting effect and production safety.
