Product Description
Refractory Launder Systems for Multi-Crystallizer Distribution
Aluminum Melt Distribution in Multi-Crystallizer Billet Casting

During aluminum billet casting, molten aluminum passes through launders, diversion channels, distribution disks, and casting pipes before entering the individual crystallizers. The aluminum melt distribution system is therefore an important part of a hot top aluminum billet casting platform.

The hot top casting platform integrates the crystallizer system, aluminum melt distribution system, cooling-water distribution system, and billet guiding system. For multi-crystallizer aluminum billet production, launder configuration, refractory material properties, and positioning are important parts of the overall equipment design.

Refractory Launder System Components
Launders & Diversion Channels

Upper casting platform components create the flow path for molten aluminum from distribution area to individual crystallizers.

Distribution Disks & Casting Pipes

Designed to distribute molten aluminum uniformly into crystallizers while reducing temperature loss during transfer.

Refractory Materials Specification

The launders and related distribution components use refractory materials engineered to:

  • Avoid chemical reaction with molten aluminum
  • Resist aluminum adhesion
  • Provide high strength and abrasion resistance
Thermal Management & Positioning

Vertical and pressure plates are arranged outside the launder system, with insulation material placed between the launders and vertical plates. This structure provides launder positioning while helping reduce molten aluminum temperature loss during transfer.

Baffle structures are also provided for emergency aluminum drainage, forming part of the supporting structure around the molten aluminum distribution area.

System Integration

The aluminum melt distribution system integrates with crystallizers featuring a two-piece water-curtain structure, forged from 6061 aluminum rod and processed through rough machining, CNC drilling and milling, and precision machining.

The platform also includes a cooling-water distribution system and water tank designed to support water distribution among crystallizers and avoid water-pressure imbalance at the inlets.

For a hot top aluminum billet casting machine, the launder system, refractory materials, crystallizers, and cooling-water system should be considered together during technical configuration and equipment selection.
