How Does Continuous Casting Aluminum Work?
Continuous casting aluminum starts by melting raw stock in furnaces at around 660°C, then refining the molten flow through degassing to remove impurities. You transfer it to a tundish, pouring steadily into a water-cooled mold where outer layers solidify first, forming a shell while the core remains liquid. Rollers guide the strand forward at controlled speeds, with secondary sprays ensuring full hardening. Ready for the good part? This mechanism yields dense microstructures, vital for your structural parts. In practice, a billet exits at 4-6 mm thickness, cut to length via saws—perfect for extrusion feeds. Temperature management hovers at 700-750°C during pour, preventing cracks through precise cooling gradients. For B2B efficiency, automation syncs withdrawal with pour rates, minimizing downtime. One automotive supplier integrated this, achieving 50 tons daily without interruptions. Variations like vertical or horizontal setups adapt to your facility layout, optimizing space. Ultimately, this workflow delivers near-net shapes, cutting secondary operations and enhancing your throughput.
| Process Step | Temperature Range | Duration | |
|---|---|---|---|
| Melting | 660°C | 1-2 hours | |
| Pouring & Solidification | 700-750°C | Continuous | |
| Cooling & Withdrawal | Ambient to 100°C | 5-10 minutes per meter |
Materials Used in Continuous Casting Aluminum
Continuous casting aluminum thrives with alloys exhibiting good fluidity and narrow freezing ranges, primarily 1xxx, 3xxx, and 5xxx series for their compatibility. You select based on end-use—pure aluminum for conductivity in wiring, or Al-Mg blends for corrosion resistance in marine parts. What’s the real story? Impurities like hydrogen demand rigorous filtration, as even trace amounts cause porosity in your high-stakes components. Common choices include 3003 (Al-Mn) for general fabrication, offering 1-2% manganese to enhance strength without brittleness. Silicon additions in 4xxx series improve castability, though limited to 1% to avoid cracking. For B2B versatility, these materials support recycling, with up to 95% scrap reuse aligning with sustainability goals. A packaging firm using 5182 alloy saw 15% better formability post-casting. Degassing units and ceramic filters ensure purity, directly safeguarding your product integrity. This selection process not only matches mechanical needs but also optimizes costs, as low-alloy feeds reduce setup complexities in your lines.
| Alloy Series | Key Elements | Typical Applications | |
|---|---|---|---|
| 1xxx | Pure Al | Electrical conductors | |
| 3xxx | Mn (1-2%) | Beverage cans, sheets | |
| 5xxx | Mg (2-3%) | Marine hulls, automotive |
