Bloom Caster

Bloom casters are heavy-duty continuous casting machines designed for large cross-sections

Key Components

  • Ladle & Turret- Holds and pours molten steel from the steelmaking furnace.
  • Tundish- Acts as a buffer reservoir, ensuring a steady flow of molten steel into the mold.
  • Mold (Primary Cooling Zone)-Initiates solidification by forming a stable steel shell.
  • Cutting System-Cuts the bloom into desired lengths (typically 6–12 m).
  • Automation & Control Systems-Mold level control ,Speed regulation and Defect detection.

Overview

Bloom Caster in Metal Casting A bloom caster is a type of continuous casting machine used in steel plants to produce blooms, which are large, semi-finished steel products with a square or rectangular cross-section (typically ≥200×200 mm). Blooms are further processed into structural beams, rails, seamless tubes, and large forged components.

Advantages

  • High-quality internal structure (reduces segregation & porosity).
  • Better yield (~96–98%) compared to ingot casting.
  • Energy-efficient (continuous process reduces reheating needs).
  • Flexibility in steel grades (works with low/high-carbon, alloy, and tool steels).
