摘要
An existing basic oxygen type top-blown steel converter vessel is transformed into a bottom-blown type where gases and finely divided materials may be blown into the vessel through tuyeres in its side wall and in its bottom. The existing trunnion shafts on which the existing vessel is supported for tilting are bored at the installation site to provide a plurality of passageways for conducting finely divided materials, gases and cooling water to the various tuyeres and to the trunnion ring which supports the vessel, respectively. Special multipurpose rotary joints are used to connect the tiltable vessel to sources of the gases and finely divided materials.
