Billet Caster
Billet casters are designed for high-efficiency, continuous production of steel billets with consistent quality.
Key Components
- Tundish – Acts as a reservoir for molten steel, ensuring a steady flow into the mold.
- Mold (Copper Mold) – A water-cooled copper mold where molten steel begins to solidify into a shell.
- Oscillation Mechanism – Prevents sticking by oscillating the mold up and down.
- Secondary Cooling Zone – Water sprays further cool and solidify the steel strand.
- Withdrawal and Straightening Unit – Pulls and straightens the solidified billet.
- Cutting Torch or Shear – Cuts the continuous strand into desired lengths.
Overview
A billet caster is a type of continuous casting machine used in steel plants to produce billets, which are semi-finished steel products with a square or rectangular cross-section (typically ranging from 50mm x 50mm to 200mm x 200mm). These billets are later rolled into bars, rods, or other finished steel products in rolling mills.
Advantages
- Higher yield compared to ingot casting
- Better internal quality (fewer defects)
- Energy and cost-efficient
- Continuous production process
