A steel making assembly comprising a metal, refractory lined vessel having a side wall with a taphole therein and a metal plug placed within the taphole. The metal plug comprises a frustoconical body having a side conical wall, a closed small end and an open large end thereof defining an essentially empty interior space. The side conical wall of the frustoconical body of the plug includes at least one diagonal compression slit. The at least one diagonal compression slit extends from the open large end of the frustoconical body and extends toward the closed small end of the frustoconical body. The conical wall has a center axis, with the at least one diagonal compression slit being non-parallel to the center axis.
