  • Patent number: 4508241
    Abstract: The invention relates to a slidable closure element for slide closures of metallurgical vessels, composed of a one-piece plate of heat resistant material which is engaged at its two opposite narrow edges by frame members that are drawn together by screws serving to tension them and hold them in contact with the edges of the plate.

  • Patent number: 4337897
    Abstract: An improvement in a process for forming a refractory lining on the interior walls of the metallurgical vessel which interior walls are coaxial to the principal axis of the vessel wherein a refractory mass containing a binder is centrifugally slung onto the interior walls in a direction normal thereto while the vessel is at a standstill is disclosed. According to the invention, the refractory mass is initially shaped into balls prior to being centrifugally slung and the balls are centrifugally slung in rapid succession to form a mass jet. Also disclosed, is a device for so slinging a refractory mass on the walls of a vessel comprising a slinger head having a slinger wheel and a motor and at least one supply conduit for supplying refractory mass to be slung. The slinger wheel of the slinger head is disposed on one end of a shaft which shaft is extendable into a vessel, the slinger wheel being connected to an actuatable by a slinger motor.

  • Patent number: 4039175
    Abstract: A process for removing dust produced in the lining of casting ladles wherein a slinging mass is slung between the inner walls of the ladle and an opposing template whereby a free space is defined between the ladle wall and the template which free space contains dust which process involves sucking the dust in the free space from a point near the upper edge of the template into a region behind the template; an apparatus for performing such a process comprising a template, a suction conduit inside said template having an inlet and an outlet, the inlet being in fluid communication with particles disposed near the upper edge of said template, the suction conduit including filtering means for filtering out entrained particles from air sucked therethrough, the filtering means including means for collecting filtered particles, the outlet end of the suction conduit includes means for sucking air therethrough.
