The structure of the oxygen passage in a supporting trunnion (41) of a steel converter vessel (1) comprises a hollow chamber (46) provided where a trunnion shaft (42) projects from a trunnion ring. In the hollow chamber (46) is inserted a hermetic manifold (47) to which a horizontal pipe (52) communicating with a rotary joint (9) and a vertical pipe (53) communicating with an oxygen tuyere in the bottom of the converter vessel (1) are welded. Inside the manifold (47) there is fitted a communicating member (59) containing a bend-like passage through which the horizontal and vertical pipes (52, 53) communicate with each other. This structure of the oxygen passage prevents the danger of an oxygen-induced combustion. |
