High-quality steel production for Peru

Corporación Aceros Arequipa SA (CAASA), based in Lima, Peru, has awarded SMS group, a systems supply contract encompassing the delivery of a new vacuum tank degasser for its Pisco site. The degasser will be integrated into the already delivered SMS group meltshop and enable CAASA to widen their production in terms of quantity and quality.

The 120-ton twin tank vacuum degasser is equipped with movable cover and mechanical vacuum pumps. Innovative robotics (TS-Pro Sampler) are installed on the cover for quick and repeatable sampling. Refining by wire feeding ensures that at the end of the treatment the heat has reached exactly the desired chemistry before the delivery of the steel to the continuous casting plant. As timing is essential the vacuum generation system has been selected with a view to rapid and consistent pump-down time, stable process behavior below 1 mbar and powerful control in case of unexpected overpressure. To protect the mechanical pumps (precisely machined roots blowers and screw compressors), a dedicated inert-type baghouse filter will be installed on the suction line between the main valve and the pump inlets.
