  • Device for piercing an obstruction in a well-block opening of a ladle for transporting molten steel
    Patent number: 5167902
    Abstract: A dart-assembly for piercing open a blockage in the opening of a ladle for holding and transporting molten steel is mounted in the outlet bore of a slide-gate associated with the ladle opening. The assembly has an outer steel housing; mounted within the housing is a dart-member having an elongated rod, which rod has a lower threaded end for receiving a threaded nut. The upper end of the rod is provided with a dart-like head-portion which actually contacts and pierces through the blockage in the opening of the ladle when the dart-member is fired. A compression spring is telescopingly mounted about most of the length of the elongated rod of the dart-member, between the enlarged dart-like head-portion and the upper, flat-surface of a stop member.
