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.
