Water-Cooled Refractory Shapes For Harsh Forehearth Superstructure Applications

Glass furnace forehearths superstructures can be environments of rather harsh conditions. This paper will serve to illustrate that water-cooled refractory shapes are a viable and cost-effective solution for previously unmanageable problem areas requiring innovative refractory techniques. This approach is a joint effort between Special Shapes refractory Co, and an end-user to resist the deleterious effects of sodium borate attack, thermal cycling, hazardous environments, and loss of production.
