板坯Slab is primary semi-finished steel product with a large, flat rectangular shape, designed as the key feedstock for rolling into flat steel products.
Slab is primary semi-finished steel product with a large, flat rectangular shape, designed as the key feedstock for rolling into flat steel products (e.g., hot-rolled coils, heavy plates, cold-rolled sheets). Distinguished from other semi-finished steels (e.g., blooms for sections, billets for bars/wire rods), slabs have characteristic dimensions: typically 150–300 mm thick, 1,000–3,200 mm wide, and 2–12 m long (varies by mill capacity). Its flat geometry enables efficient conversion into wide, thin steel products critical for construction, automotive, and industrial sectors.
钢坯Billet is key semi-finished steel product with a small, uniform cross-section.
Billet is key semi-finished steel product with a small, uniform cross-section—typically square (100–200 mm side length) or round (100–200 mm diameter)—and a length of 3–12 meters. Unlike slabs (flat, for flat steel) or blooms (larger cross-sections, for structural sections), billets are specifically designed as feedstock for rolling into long steel products (e.g., bars, wire rods, seamless tubes) or for forging into precision mechanical parts. Its compact, regular cross-section enables efficient deformation into narrow, elongated finished goods critical for construction, automotive, and machinery industries.
Bloom/ CC 轮Blooms are large semi-finished steel products with a rectangular or square cross-section.
Blooms are large semi-finished steel products with a rectangular or square cross-section, typically used as feedstock for further hot rolling into intermediate or finished steel products. They are a key intermediate in the steel manufacturing chain, bridging primary steelmaking (e.g., BOF, EAF) and downstream processing.
生铁Pig iron is a primary iron-carbon alloy produced by smelting iron ore in a blast furnace.
Pig iron is a primary iron-carbon alloy produced by smelting iron ore in a blast furnace. It serves as the foundational raw material for steelmaking and cast iron production. The name originates from historical casting practices, where molten iron was poured into sand molds arranged in a “sow-and-pig” pattern (a large central mold “sow” feeding smaller “pig” molds), forming ingots resembling small pigs.
