ABSTRACT:
A guide trough for molten products comprising an elongated body made of monolithic refractory material. A runway for conducting molten products is formed in the top surface of the elongated body, and a pair of reinforcing beams are embedded within the elongated body extending longitudinally thereof on opposite sides of the runway and proximate the top surface in which the runway is formed. Cross-members are spaced apart longitudinally of the elongated body and extend across the bottom thereof for interconnecting the reinforcing beam. Recesses in the elongated body expose portions of the reinforcing beams to render accessible portions of the reinforcing beams to allow them to be engaged, in use, by hooks for lifting the guide trough.
