ABSTRACT:
An apparatus for sealing the skirt of a converter waste gas recovery system is disclosed, which includes an annular flange that is mounted about the outside surface of the converter adjacent to its mouth at a point clear outside the reach of the molten slag and metal that might spill over the rim of the converter mouth during the process of blowing. An annular sealing band is provided at the lower peripheral portion of the skirt, which runs surrounding the mouth. The annular sealing band is divided into multiple arcuate segments of a whole bandage, each pivotally disposed on a horizontal pin and connected to a separate hydraulic cylinder through its axially movable piston rod. It is so designed that the segments of the annular sealing band are individually yet simultaneously swung about their respective pins by their hydraulic cylinders into abutting contact with the external periphery of the flange providing a tight leakproof seal. In the contacted surfaces of the annular sealing band and the flange, sealing is most unlikely impaired by clumps of solidified slag and metal spilled in molten state from the converter mouth as in the skirts of conventional waste gas recovery systems.
