Linear sliding gate valve for a metallurgical vessel

A linear sliding gate valve for a metallurgical vessel, comprising:

• a slide plate having a first orifice;
• a fixed plate having a second orifice;
• a slideable tray comprising a rotatable slide plate support for supporting said slide plate such that said slide plate is rotatable relative to said slideable tray, said slideable tray being arranged to slide said slide plate relative to said fixed plate for controlling an outflow of a metallurgical vessel by the relative position of said first and second orifices;
• and
• a ratchet mechanism for rotating said slide plate relative to said slideable tray and providing defined angular positions of said slide plate;
• and
• a clamping ring mounted on said rotatable slide plate support for fastening said slide plate, said clamping ring comprising a plurality of resilient fastening members for resiliently fastening said slide plate to said clamping ring.
