Abstract
Abstract A probe assembly for a converter is disclosed and has a frame and a mounting head pivotable on the frame. Mounting head rotating means are connected to the mounting head for causing relative movement between the frame and the mounting head. A boom is pivotable on the mounting head and boom rotating means are connected to the boom by causing relative rotative movement between the mounting head and the boom. A probe holder is pivotable on the free end of the boom, a probe holder rotating means is connected to the probe holder for causing relative rotative movement between the probe holder and the boom, and a probe is disposed on the probe holder. The probe holder rotating means are operable to rotate the probe holder and the probe on the boom from a probe park position adjacent the boom, away from the boom and toward the mouth to a probe mouth clearing position. The mounting head rotating means rotates the mounting head from a mounting head park position on the frame through an intermediate mounting head position to a mounting head sampling position where the mounting head is in the sampling position and where the probe can clear the mouth to move into the probe sampling position. The boom rotating means rotates the boom on the mounting head from the boom park position to the boom sampling position and the probe holder rotating means rotates the probe holder on the boom to a probe sampling position where the probe passes through the slag and into the molten metal.
