Launder System for Aluminium Casting with Anti‑Stick Fused Silica

Product Overview： 

Our advanced Molten Aluminum Launders (Transfer Launders) are built for modern aluminum casthouses, foundry operations, and alloy melting shops. Featuring specialized high-alumina/calcium-silicate refractory linings paired with a rugged steel exterior structure, these launders ensure smooth, turbulence-free flow during aluminum transfer from melting furnaces to holding furnaces, degassing units, or casting machines (DC casting & continuous casting).

The high-contrast blue/white functional refractory lining shown in the system provides superior corrosion resistance against aggressive molten aluminum and magnesium-containing alloys, ensuring pure melt output and minimal maintenance downtime.

Key Advantages & Features：

1. Superior Non-Wetting Refractory Lining

Anti-Stick Surface: Specially formulated refractory lining with anti-wetting agents ensures molten aluminum slides smoothly without adhesion.

Easy Slag Removal: Dross and residual aluminum are extremely easy to clean after casting operations, preventing structural clogging.

2. High Thermal Efficiency & Energy Savings

Low Thermal Conductivity: Multi-layer insulation structure reduces radiant and conductive heat loss dramatically during transfer.

Process Stability: Maintains steady molten metal temperatures, reducing the need for superheating in the furnace and cutting electricity/gas costs.

3. Precision Engineering & Modular Design：

Custom Routing: Available in straight lines, 90° elbows, T-branches, and Y-divides (as shown in the product image) for flexible factory layout integration.

Seamless Joints: Engineered inter-segment sealing prevents aluminum leakage and cold-lap thermal bridges.

4. Structural Durability & Safety

Heavy-Duty Casing: Structural steel frame with integrated lifting lugs and alignment pins ensures easy installation, maintenance, and crane repositioning.

Thermal Shock Resistance: Designed to handle severe temperature gradients during preheating and molten metal introduction without cracking.

Why Choose Us / Quality Assurance:

Custom Tailoring: Every launder design is customized based on your flow rate (t/h), temperature requirements, and factory floor plan (CAD drawings provided).

Pre-Dryed & Ready to Preheat: Linings are thermally cured prior to shipment to eliminate moisture risks and speed up on-site commissioning.

Global Delivery & Installation Support: Expert engineering assistance available for installation guidance, sealing setup, and pre-heating protocols.

FAQ Section: 

Q1: How do you prevent molten aluminum leakage between launder joints?

We utilize high-temperature ceramic fiber gaskets and interlocking mechanical flange connectors to form a leak-proof, expansion-resistant joint between sections.

Q2: Can we request custom shapes like T-junctions or flow control dams?

Yes! As shown in our product showcase, we specialize in T-sections, flow dividers, dam slots, filter box connectors, and automated flow control gate integrations.

Q3: What is the typical lifespan of the refractory lining?

Depending on melt volume, alloy composition, and maintenance practices, our linings typically achieve 12 to 36 months of continuous operation.
