Patent number: 6619619Abstract: 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.Type: GrantFiled: September 3, 2002Date of Patent: September 16, 2003Assignee: Vesuvius Crucible CompanyInventors: Vincent Boisdequin, Philippe Mutsaarts
