The launder dam is designed to work in conjunction with the launder. It is constructed from advanced NR-80 technical calcium silicate material, specifically for controlling the flow of molten aluminum. This product is resistant to corrosion and does not contaminate the molten aluminum, making it suitable for high-value, high-tech aluminum casting applications.
Trough and launder systems facilitate the movement of molten alloys from one site to another using gravity. These systems generally comprise a hot-face refractory lining, backup insulation, structural steel components, dams, and various high-temperature apparatus, including thermocouples and gaskets. They are primarily employed to transfer metal from a melting furnace to a holding furnace, from a holding furnace to a casting station, or to direct metal to inline degassing and filtration systems. Well-designed trough systems are crucial for maintaining the temperature of the metal and minimizing oxide formation. In foundries, troughs are commonly utilized for transporting metals from melting furnaces to holding furnaces. The configuration and size of trough systems can differ, but they typically feature a refractory hot-face lining and insulation encased within a steel shell. Trough designs must consider factors such as metal flow rate, temperature at the casting station (including heat loss over distance), the specific alloys being cast, and other relevant variables.
