Slabs

Slabs

Slabs are broad, flat steel pieces with a rectangular cross-section, typically 230 mm thick and up to 1500-2500 mm wide, with lengths ranging from 6 to 12 meters. They are produced through continuous casting or rolling from ingots and are primarily used to produce flat-rolled products.

• Dimensions: Thickness (50-300 mm), Width (1000-2600 mm), Length (up to 12 meters)
• Chemical Composition: Varies based on the intended application, typically including elements like carbon, manganese, silicon, sulfur, and phosphorus.

Applications

1. Hot-Rolled and Cold-Rolled Coils:
   • These are processed into hot-rolled coils through reheating and rolling, further processed into cold-rolled coils for automotive and appliance manufacturing.
2. Plates:
   • Used to produce heavy steel plates for shipbuilding, construction, and pressure vessels.
3. Pipes and Tubes:
   • Slabs are transformed into pipes and tubes used in the oil and gas industry, water supply systems, and structural applications.

Manufacturing Process

• Continuous Casting: Molten steel is poured into a continuous casting machine, solidifying it into slabs.
• Reheating: Slabs are reheated in a furnace before being rolled into various shapes and sizes.

Advantages

• Versatility: Can be processed into a wide range of products.
• Efficiency: Continuous casting is a cost-effective and efficient production method.
• Quality: Produces high-quality steel with consistent properties.
