Molten Aluminum Launder Transition Ring High Density Calcium Silicate Launder Connector

Our launder transition ring is a high-density calcium silicate refractory preform, with its inner surface coated by spraying boron nitride (BN) to prevent aluminum adhesion. It is designed to serve as an intermediate connection component among the aluminum launder, in-line degassing unit, and molten aluminum filter box, ensuring a smooth transition of the molten aluminum melt, minimizing flow turbulence, and reducing dross entrainment. Custom dimensions are available to accommodate various aluminum casting working conditions.

FAQ

Q1: What is the function of launder transition ring? A1: It acts as transition joint between different molten aluminum processing equipment, makes aluminum liquid flow smoothly, reduces turbulence and slag.

Q2: Why apply BN coating on inner surface? A2: BN coating is non‑wetting with molten aluminum, avoids aluminum sticking and slag accumulation on refractory surface, simplifies daily maintenance.

Q3: Can you produce non‑standard sizes? A3: Yes. We support custom machining as per your dimension drawings for existing launder & equipment retrofitting.

Q4: Which aluminum processing equipment can this ring match? A4: It is widely matched with aluminum launder, tilting in‑line degassing unit and molten aluminum filter box in aluminum foundry plants.
