Less than nine months from signature to caster start-up – New billet caster concept from Siemens shortens project time

A new billet caster concept with a designed throughput rate of maximum 400,000 t/a was developed by Siemens VAI that enables quality products to be cast with economy billet casters commensurate with local market conditions.

capacity of 200,000 t/a

On the basis of a reengineered plant design, complimented by an extended logistics and sourcing network, billet casting projects can be completed more quickly, efficiently and at lower costs in comparison with conventional engineering and plant-building concepts.

The availability of different caster machine variants in combination with modular plant expandability allows producers to tailor their plants to current and future market requirements.

The highly compact plant design with a bow radius of six meters foresees the installation of one to four billet strands, each with an annual casting capacity of approximately 100,000 tons of carbon steel grades. Operation of the individual strands can be carried out independently of each other, thus assuring optimum caster utilization in accordance with the availability of liquid steel. Strand formats range from 100x100 mm to 200x200 mm. The cast products will be typically rolled to bars and wires for infrastructural applications.

All construction elements, machine components and systems are modularly designed and preassembled in the workshop to the greatest extent possible. Installation of equipment and technological packages is based on the Siemens VAI Connect & Cast principle, ensuring that plant functions and systems are fully operational from the first heat on. In this way, erection, start-up and commissioning can be completed within several weeks. Caster upgrading and expansion is carried out in steps depending on customer and market requirements. The extensive worldwide network of Siemens workshop and service centers, supported by regional manufacturing resources, ensures that equipment and components can be quickly delivered to the plant site. This new generation of economy billet casters with notably short installation periods allows local and emerging companies to quickly respond to rapidly changing market demands for steel.
