Siemens VAI Metals Technologies has started up the LD (BOF) converter and continuous slab caster of the second production line of the ThyssenKrupp CSA Siderùrgica do Atlântico steel mill.

The first slab was cast on the first line in September. The steel works is designed to produce some 5Mt/y of slab.

Siemens VAI supplied two basic oxygen furnace plants, secondary metallurgical facilities, primary and secondary dust-cleaning systems, two continuous slab casters, and the associated electrical and automation equipment.

The steel mill is located in Sepetiba in state of Rio de Janeiro and steel is produced in two 330-ton LD (BOF) converters.

Slabs with widths of 800mm to 2000mm, thicknesses of 200mm to 260mm and lengths from 6 to 12m can be cast on the slab casters.
