Graphite Launder

Manufactured from specially formulated, fine-grained, high-strength graphite with an extremely low coefficient of thermal expansion. Combined with an optimized structural design, it withstands repeated thermal shocks from room temperature to over 800°C, minimizing cracking and ensuring safe, continuous operation.

High-density graphite is non-wetting to most molten metals (especially aluminum). We provide a high-precision machined surface, ensuring smooth, unrestricted metal flow. This significantly reduces metal residue and oxide dross formation, improving metal yield.

The material's strength increases at elevated temperatures. The high density provides outstanding resistance to erosion and abrasion, maintaining precise geometry and dimensional stability even during prolonged high-temperature service.

We offer launders impregnated with an optional anti-oxidation protective coating. This coating forms a dense protective layer on the graphite surface, effectively raising the oxidation onset temperature by 200-400°C, significantly extending product life in oxidative environments.

We provide fully customized design and machining based on your furnace type, flow rate, installation space, and angle. This ensures perfect flange mating, precise tilt angles.
