CCM Upgrade @ ArcelorMittal Olaberria, Spain

CCM Upgrade @ ArcelorMittal Olaberria, Spain

Sarralle was selected to upgrade the BBL Continuous Casting Machine at ArcelorMittal Olaberria. The project scope included the design and supply of two new Tundish Cars, new Tundishes and an additional straightening unit in each strand.

Tundish Car:

Two new tundish cars have been supplied with lifting/lowering capability to allow it to work with a minimum distance between tundish and mould.


The new tundishes are designed with an increased liquid steel bath height guaranteeing consistent steel casting speeds and uniform temperature in each strand.
Straightening units:

The two existing straightening units in each strand have also been upgraded with an additional third unit without changing the oscillators nor caster pass-line radius. The machine is now capable of progressive straightening which contributes to improvements in the quality of the cast billet.
