1. What is a steel billet?

Steel billet is a semi-finished product in the steel industry, typically a square or rectangular cross-section of steel that is hot rolled or forged. It is produced through a process of casting molten steel, then allowing it to solidify into a rectangular shape. Billets serve as raw material for further processing into finished steel products such as bars, rods, and structural shapes.

Key characteristics of steel billets include:

1. Shape and Size: Billets are generally square or rectangular in cross-section with dimensions typically ranging from 100×100 mm to 200×200 mm or larger, depending on the intended use and manufacturing process.
2. Composition: They are made primarily from carbon steel, though alloy steels and stainless steels can also be cast into billets depending on the desired end product.
3. Production: Billets are often produced through continuous casting, where molten steel is poured into a water-cooled mold, solidifying into the desired shape. They can also be produced through ingot casting followed by hot rolling or forging.
4. Uses: Billets serve as feedstock for further processing in rolling mills or forging operations to produce final products such as bars, rods, wires, structural sections, and seamless tubes.
5. Quality Control: The quality of billets is crucial as it directly affects the quality of the final steel product. Quality control measures include ensuring uniform composition, absence of defects, and precise dimensions.

In summary, steel billets are intermediate products in the steel manufacturing process, essential for producing a wide range of finished steel products used in construction, manufacturing, infrastructure, and various industrial applications.

2. What are the technologies used in steel billet production?

Steel billet production involves several technologies and processes to transform raw materials into semi-finished products that can be further processed into final steel products. Here are the primary technologies and processes used in steel billet production:

1. Electric Arc Furnace (EAF)

• Process: Scrap steel or direct reduced iron (DRI) is melted in an electric arc furnace. The furnace uses electric arcs from electrodes to generate the heat required to melt the raw materials.
• Advantages: EAF is flexible in terms of raw materials and energy efficiency. It is suitable for recycling scrap steel.

2. Basic Oxygen Furnace (BOF)

• Process: In the BOF process, molten iron from a blast furnace is mixed with scrap steel. Oxygen is blown into the mixture at high speeds, reducing carbon content and converting it into steel.
• Advantages: BOF is efficient for large-scale production and can produce steel with low impurity levels.
