A particular type of trough and launder has a channel for directing a stream of molten metal to flow from a furnace to a mold. Such a trough, which is known as a launder, is typically formed in sections that are connected end-to-end. The launder may have a cover over the channel, and may include heaters for maintaining the metal in the liquid state fully along the flow path from the furnace to the mold.
An apparatus for use with a launder shell includes a heating component. The heating component is formed of refractory material, and has a compartment configured to contain an electrical heating element. The apparatus further includes an elongated trough section configured for placement in an installed position inside the shell. The trough section has a fluid flow channel and a cavity beneath the channel. The cavity is configured to receive and support the heating component for movement into and out of the installed position together with the trough section.
Summarized differently, an apparatus includes an elongated trough section configured for placement in an installed position inside a launder shell. The trough section has a fluid flow channel, and has a convex refractory surface facing downward beneath the channel. The apparatus further includes a heating component with a compartment configured to contain an electrical heating element. The heating element component has a concave refractory surface configured to face upward toward the convex refractory surface of the trough section.
Adtech trough and launder systems provide greater flexibility in the molten metal casting process. Smooth transportation is the key to the quality of the aluminum melt, because any turbulence may cause oxides in the aluminum melt. The Adtech launder system is designed with this in mind, eliminating any form of agitation in every step. It can make the aluminum liquid transfer smoothly, without secondary pollution, and the quality is better.
