Abstract
Disclosed is a valve and refractory construction in which the stationary plate and the sliding gate are of a bandless refractory. Similarly the lower nozzle, and collector nozzle are also bandless, along with the optional collector tip. Various refractory shapes are contemplated, but primarily a shape with a tapered face on the edge of the refractories, and which are engaged by clamps having a mating tapered face. The refractory can also be made in a single form for both the stationary plate and the sliding gate. All of the refractories are clamped in place by clamping members having tapered faces which engage the tapered faces or edges of the refractory. The nozzles are similarly engaged, but by an encircling support and clamp.
Claims23
A refractory plate for use with a sliding gate valve comprising
- a refractory slab having opposite faces,
- one face being a sliding face and one face being a mounting face,
- said slab having edge portions between the opposite faces,
- at least two opposed edge portions being tapered,
- said slab width and length enlarging progressively from the sliding face towards the mounting face along substantially the entire extent of the tapered edge portions,
- said taper permitting central and mounting compressive forces on the edges when engaged by a clamp having a mating tapered face.
A refractory plate for use in a sliding gate valve comprising
- a refractory slab having opposed edge ends and edge sides and a sliding face and a mounting face,
- one edge side having a tapered portion,
- one end edge having a tapered portion,
- said slab width and length enlarging progressively from the sliding face towards the mounting face along substantially the entire extent of the tapered edge portions,
- the angle of each face permitting an opposed clamping member to exert both central and downward pressure components,
- the downward component being directed against a support for the refractory.
The method of mounting refractory plates having a parallel sliding face and mounting face and tapered edge portions, said plates width and length enlarging progressively from the sliding face towards the mounting face along substantially the entire extent of the tapered edge portions, in a sliding gate valve comprising the steps of
- tapering opposed edges of the refractory plates,
- clamping the tapered edges of the refractory plates with central and mounting pressure components,
- positioning said plates within a clamping peripheral engagement.
A sliding gate valve for use with a bandless refractory, said valve having a stationary plate and a sliding gate, a carrier for moving the sliding gate, a frame for receiving the carrier, means for driving the carrier, and yieldable means for urging the sliding plate in pressure face-to-face relationship with the stationary plate, said stationary plate and sliding gate each having opposite faces, one face being a sliding face and one face being a mounting face, said plates having edge portions, at least two edge portions being tapered, said plates having a width and length enlarging progressively from the tapered edge portions in the direction of the mounting face and away from the sliding face along substantially the entire extent of the tapered edge portions, characterized by
- tapered clamping means for engaging said tapered edge portions of said plates,
- means for engaging said clamping means and urging the same in a direction opposite from the sliding face,
- whereby a central compressive force component and a clamping component are developed as the engaging means engage the clamping means.
