Trough Dams

Overview

Trough dams are inserted inside the launder cross section to block molten metal from moving past. 

Pyrotek Offerings

Pyrotek offers trough dams that are pre-cut, moulded or cast pieces of board or refractory that fit snugly inside the launder cross section and block molten metal from moving past. Trough dams can have an automatic lift system that provides the capability of a hands-free automated cast start. Pyrotek trough dams can have a dam gasket wrapped around the outside to ensure a better seal against the refractory, or they can be inserted into a groove and compressed against the refractory lining.
