Aceros Arequipa orders vacuum tank degasser

Corporación Aceros Arequipa, based in Lima, Peru, has awarded SMS 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 meltshop and enable CAASA to widen their production in terms of quantity and quality.

The degassing process aims at reaching the lowest possible level of hydrogen content in the steel, which is a necessary precondition for CAASA to produce top-quality high-carbon grades for grinding balls. Nitrogen removal and oxygen control are other very important factors for the production of further SBQ grades.

The full integration of the new vacuum degasser into the electric steelmaking route will set a new benchmark in South American steelmaking: for the very first time, both high productivity and high quality come together in a compact and optimized layout.

Commissioning of the degasser is scheduled for early 2022.
