ABSTRACT:
A sliding gate valve arrangement is provided with a molten metal vessel having an outlet and guide tracks secured to the vessel extending transverse to the outlet. The housing frame is slidably mountable on the guide tracks. The housing frame has a refractory base plate and a slider unit therein and a plurality of spring elements. The slider unit includes a refractory sliding plate that can be sealingly pressed into engagement with the refractory base plate with the spring elements. A drive element is connectable with the slider unit for moving the slider unit back and forth. The guide tracks are of a predetermined length such that the housing frame, when disposed on the guide tracks, is slidable over a predetermined distance between a first position in which the housing frame positions the refractory base plate and the slider unit below the outlet of the molten metal vessel and a second position in which the housing frame is released from the guide tracks and the molten metal vessel. A coupling is provided on the housing frame for engagement with the manipulator. The manipulator is used to move the housing frame and the guide tracks between the first and second positions for removing and installing the housing frame on the vessel.
