  • Patent number: 6533147
    Abstract: The present invention concerns a pouring tube of refractory material comprised of a tubular element and equipped at its upper end with a plane plate, the side faces and lower face of the said plate and the upper end of the tubular part being protected by a metallic case, said plate being reinforced in its lower face by mechanical means that increase its stiffness that is characterized in that these stiffening means are comprised of a plurality of U-shaped metallic pieces located on either side of the tube and attached fixedly to the part of the metal case protecting the lower face of the plate. These tubes present a greater resistance to the formation of cracks than conventional tubes.

  • Publication number: 20030038268
    Abstract: The object of the present invention is a clamp for clamping device for a refractory plate in a seating of a slide valve in a casting installation, the said clamp having on one hand a thrust zone whereon it can receive a clamping force tending to push the clamp against a refractory plate located in the seating and, on the other hand, two ends of which each is capable of being applied against one edge of the refractory plate. The clamp is characterised in that it is capable of being elastically deformed in that each of its two ends is conformed such that it bears against the corresponding edge of the refractory plate when a clamping force is applied to the clamp also bears against the wall of the seating under the effect of expansion of the plate or a greater clamping force.

  • Publication number: 20020189676
    Abstract: The invention relates to a refractory plate (1) for a slide gate valve, having a pouring hole (3), circumscribed by a circle C of center (4), at least a portion of the edges (15, 16, 17, 18) of the plate (1) are angularly oriented so as to focus the clamping forces optimally in the throttling area and around the pouring hole.
