Moulds for Continuous Casting Machines
Exima PRO supplies moulds for all types of continuous casting machines—slab, bloom and billet—and provides comprehensive engineering solutions, from custom design to components and complete continuous-casting lines.
Applications:
Continuous casting machines.
Vacuum arc remelting furnaces.
Operating Principle:
1. Metal pouring: a starter bar forms the base for the first metal charge.
2. Strand formation: after solidification, the starter bar withdraws the strand while liquid metal continues to enter.
3. Secondary cooling: the strand fully solidifies downstream of the mould.
4. Electromagnetic field: a controlled field promotes uniform crystal structure and minimizes defects.

- High-conductivity copper walls for efficient cooling.
- Vacuum-remelting system for VAR furnaces:
- Sealed vacuum chamber.
- Water-cooled mould.
- Power-supply and vacuum-pump systems.
Design Features:
- The mould is the key element of a continuous casting machine, where liquid steel enters a water-cooled form and solidifies at the surface to create a stable shell while the core remains liquid. This process produces continuously cast billets with a uniform structure.
- Technology Benefits:
- • 15–25% lower trimming losses compared with ingot casting
- • Uniform billet structure along the entire length
- • Continuous production of billets in virtually unlimited lengths
