Launders often referred to as troughs, utilize gravity—occasionally assisted by a pumping system—to move molten metal through a network of specially engineered high-temperature channels from one site to another.
Launder systems integrate various elements, including hot-face refractory, backup insulation, a steel shell, and support structures, along with heated or unheated lids, dams, and other high-temperature components like thermocouples and gaskets, to facilitate the movement of molten metal. Trough systems are designed for multiple transport functions, leading to a variety of trough styles and components.
The distribution launder features a durable lining that is positioned between the casting mold plate and the integrated launder. This lining is constructed from calcium silicate boards or advanced high-silicon melting materials, offering corrosion resistance and preventing molten aluminum from sticking. Additionally, it does not contaminate the molten aluminum, making it suitable for high-value, high-tech aluminum casting applications.
Exceptional hardness and erosion resistance, along with precise geometric accuracy, result in low maintenance expenses and a smooth surface finish.
The material does not peel or contaminate molten aluminum, significantly enhancing the quality of aluminum alloys.
It offers strong thermal shock resistance, minimizing contamination of molten aluminum during corrosion-resistant casting processes.
When used in conjunction with BN, it can support 450-800 casting cycles, contributing to energy efficiency.
