3. Manufacturing Techniques for Vanadis 10 Aço estrutural
Producing Vanadis 10 requires advanced powder metallurgy processes to control carbide distribution and ensure uniform properties—critical for its performance. Aqui está o processo detalhado:
1. Produção primária
- Metalurgia em pó: High-purity iron, cromo, vanádio, and other alloy powders are mixed in precise ratios (matching Vanadis 10’s chemical composition). The mixture is compacted into green compacts under high pressure (800-1000 MPA) to form dense blanks.
- Vacuum sintering: Compacts are sintered in a vacuum furnace at 1200-1250°C for 2-4 horas. This fuses the powder particles into a solid material, eliminating porosity and ensuring uniform carbide distribution—key to Vanadis 10’s toughness.
- Forno de arco elétrico (Eaf): For small batches—scrap steel and alloying elements are melted at 1650-1750°C. Real-time sensors monitor composition to meet Vanadis 10’s standards, though powder metallurgy is preferred for premium properties.
- Remolição de arco a vácuo (NOSSO): Opcional, for ultra-pure Vanadis 10—sintered ingots are remelted in a vacuum to remove impurities (Por exemplo, oxigênio, azoto), further improving material uniformity and toughness.
2. Processamento secundário
